Description

Field of the invention

The present invention relates, inter alia, to an apparatus having means for controlling the use of energy provided by one or more power generators in a home network.

Background of the invention

Home control systems are known in the art, such as the RWE SmartHome home control system offered by the assignee. Such home control systems, for example, with the help of Zwischensteckervorrichtungen, which are (remote) controllable from a central home control device, the switching on and off of energy consumers in a home network, such as household appliances.

Summary of some exemplary embodiments of the invention

If home control devices are used in households where there are also one or more power generators, such as photovoltaic systems, household appliances could be switched on and / or off by programming the home controller such that they run, for example, when the power generators usually provide sufficient power provides for the operation of household appliances, for example at noon in the case of a photovoltaic system. Domestic appliances, for example, to run only once for a certain period of time in the course of a day, such as a dishwasher, could thus use the power usually provided by photovoltaic systems at noon, so that the operation of household appliances usually no energy from a public energy network in the home network must be fed. Also, such home appliances could be turned on primarily at night when the demand for power in the public power grid is usually low.

However, such control of the energy consumers in the home network by the home controller then allowed only a very inflexible and ultimately inefficient control of the use of energy provided by one or more power generators in a home network.

An automatic adaptation of the control, for example to an unusual weather situation (eg a longer bad weather period in the summer), an unusual energy requirement (eg repeated washing / drying after a vacation) or an unusual demand for services, would not be possible instead the timing of a situation (ie, if necessary) by a user of the home control device (re) programmed.

It is an object of the invention, inter alia, to provide improved control over the use of energy provided by one or more power generators in a home network.

This object is achieved inter alia by a device comprising means for controlling the use of energy provided by one or more power generators in a home network and / or for a home network. Controlling the use of at least a function of a forecast in the future of the energy producers provided energy and / or a forecast of future energy needs of one or more energy consumers in the home network.

Furthermore, the object is achieved inter alia by a method comprising controlling the use of energy provided by one or more power generators in a home network and / or for a home network. The control takes place at least as a function of a prognosis in the future of the energy producers provided energy and / or a forecast of future energy needs of one or more energy consumers in the house network. Furthermore, the object is achieved inter alia by a computer program comprising program instructions, wherein the program instructions cause a processor to execute the method according to the invention when the computer program is executed by the processor; The energy provided by one or more power generators in the home network and / or via the home network is, for example, electrical energy, thermal energy and / or gas energy. The one or more power generators are connected, for example, to the home network, for example by an inverter. The energy producers are, for example, a photovoltaic and / or solar thermal plant, a wind power plant, a combined heat and power plant, a biogas plant and / or a geothermal plant.

The home network is preferably the energy distribution network for a household, for example the energy distribution network in a building, in particular in a residential building, for example in a single or multiple dwelling. For example, the domestic network is a hot water pipe system of a heater or an electrical pipe system of a House power supply. The home network is connected, for example, to a public energy network, such as a local or district heating network or a public power grid, and can be fed by it. The energy that is provided by one or more energy producers in the home network, for example, from the home network in the public energy grid can be fed. An energy producer or an energy consumer in the household network is to be understood as meaning, for example, an energy producer or energy consumer connected to the household network. The one or more energy producers are, for example, all energy producers connected to the household network, or only some of the energy producers connected to the household network.

One or more energy consumers can be connected to the household network, which can cover their energy needs at least partially (or completely) with the help of the energy distributed through the household network. The energy consumers, for example, with a home control system wirelessly or wired connected and controlled by a central home control device (remote). The one or more energy consumers are, for example, all energy consumers connected to the household network, or only some of the energy consumers connected to the household network.

Under an energy consumer to be understood, for example, an energy converter, the z. B. electrical energy and / or heat energy in kinetic energy, light energy and / or heat energy can convert, or an energy transformer, the z. B. can transfer heat energy from one substance to another substance. An energy consumer is for example a household appliance, such. As a washing machine, a dryer, a dishwasher, a lamp, a radiator, a radiator, a floor heating, a heat exchanger, a stove, an oven, a multimedia device (eg., A TV or stereo), air conditioning, a Ventilation system, a refrigerator or a freezer.

By using energy provided by one or more power generators in the home network, it is intended, for example, to mean consuming (eg, converting or transmitting) at least a portion of the energy through one or more energy consumers in the home network and feeding the surplus energy from the home network into a public energy grid. The excess energy is, for example, part of the energy provided by the energy generators in the home network that is not consumed by any energy consumer in the home network.

It is also conceivable, for example, that the energy provided by the one or more energy producers in the home network is completely consumed by the energy consumers in the home network or completely fed into the public power grid. Furthermore, it is conceivable that the energy provided by the one or more energy producers in the home network is fed into the public energy grid at least to a constant and / or variable part (eg continuously).

The means for controlling the use of energy include, for example, means for controlling one or more energy consumers in the home network, for example by a home control system. For this purpose, the device is, for example, a central home control device. For example, the central home control device is connectable to home control system devices, particularly power generators, inverters, intermediate plug devices, sensors such as utility meters and / or feed meters, and / or energy consumers such as home appliances. The devices connected to the central home control device are, for example, at least partially controllable by the central home control device, for example, at least on and / or off. For example, at least some of the energy consumers in the home network are controllable by the central home control device.

The connection to the devices of the home control system is preferably a secure connection, for example an encrypted connection. The connection can take place in a wireless and / or wired connection network, preferably in a local connection network (LAN), for example a wireless local connection network (WLAN). Examples of interconnection networks are: the X10 home networking network, the European Installation Bus (EIB), the Powerline Communication Bus (PLCBUS), the Local Control Network (LCN), the ZigBee wireless network, the Z-Wave wireless network, the BidCoS wireless network, the CosIP wireless network, the Bluetooth wireless network and the IEEE 802.11 wireless network. The means for controlling the use of the energy comprise, for example, a communication unit that is set up to establish a connection via such a connection network.

The means for controlling the use of the energy include, for example, a processor unit which is set up to carry out the method according to the invention. For example, the computer program according to the invention comprises program instructions that cause the processor unit to carry out the method according to the invention, when the computer program is executed by the processor unit. A processor unit is, for example, a control unit, a microprocessor, a microcontroller such as a microcontroller, a digital signal processor (DSP), an application-specific integrated circuit (ASIC) or a field programmable gate array (FPGA).

For example, a computer program can be distributed over a network such as the Internet, a telephone or mobile network, and / or a local area network. The computer program may be at least partially software and / or firmware of the processor unit. In particular, the computer program according to the invention is, for example, software and / or firmware of a processor unit of a central home control device. The computer program is contained, for example, on a computer program product, in particular a computer-readable storage medium, which is designed, for example, as a magnetic, electrical, electromagnetic, optical and / or different type of storage medium. Such a computer-readable storage medium is for example portable or permanently installed in a device. Examples of such a computer readable storage medium are volatile or non-volatile random access memory (RAM) or read only access (ROM). The computer-readable storage medium is touchable, for example, d. H. reified. Computer readable is to be understood in particular as meaning that the storage medium can be read by a computer, for example by a processor unit.

Controlling the use of the energy, for example, allows the energy provided by the one or more power generators in the home network to substantially meet the energy needs of the one or more energy consumers. Preferably, controlling the use of the energy further enables the power provided by the one or more power generators in the home network to substantially meet the power requirements of the one or more power consumers. For example, only energy from a public energy network is fed into the home network, if otherwise the energy needs and / or the power requirements of one or more energy consumers in the home network can not be met.

The control of the use of energy takes place, for example, as a function of a forecast of the future energy demand of one or more energy consumers in the household network. For example, the forecast describes a limited future period (eg, the next 2, 4, 8, 12, or 24 hours, or 2, 3, 4, 5, 6, or 7 days.

The forecast of the future energy demand of the one or more energy consumers in the home network is preferably a prognosis of the time profile of the future power requirement of the one or more energy consumers. A time profile of a power requirement, for example, a consumption profile is understood. A consumption profile of one or more energy consumers describes, for example, the time course of the power requirement over a day, daily consumption profile, or over a switch-on period. A standardized daily consumption profile is, for example, the so-called standard load profile H0.

The prognosis, for example, takes into account a known future energy demand of at least one of the energy consumers in the home network and an estimated future energy demand of at least one of the energy consumers in the home network, preferably a known future consumption profile of at least one of the energy consumers and an estimated future consumption profile of at least one of the energy consumers ,

It is known, for example, the future energy needs and / or the future consumption profile of an energy consumer in the house network, which is turned on at a certain switch-on in the course of a day a certain time. For example, the future energy demand and / or the future consumption profile of a lamp is known, for example, which lights up every evening for a certain time (eg with the aid of a timer of 18: 00-22: 00).

For example, the future energy demand and / or the future consumption profile of an energy consumer in the home network, which is usually switched on at one or more points in the course of a day for a specific time, is estimated. For example, at least substantially known is the future energy demand and / or the future consumption profile of a freezer, the compressor of which runs a period of time at substantially periodic intervals. In addition, for example, the future energy needs and / or the future consumption profile of a cooker estimated, which is usually turned on at a certain time of the day for a certain time, for example, for the preparation of food.

For example, the apparatus comprises means for detecting the energy demand and / or power demand of the one or more energy consumers in the home network and / or for detecting the consumption profile of the one or more energy consumers in the home network. For example, with a central home control device a home control system consumption meters connectable, which are set up to capture the energy needs, power requirements and / or the consumption profile of one or more energy consumers in the home network and to send to the central home control device. A household consumption meter can record, for example, the energy demand and / or power requirement of all energy consumers in the household network and / or the consumption profile of all energy consumers in the household network.

The consumption meter can for example be designed as an intermediate connector or integrated in adapter (for example, switchable adapter). In addition, power consumers connected to a central home control device of a home control system may send to the central home control device their internally detected energy demand and / or their internally detected consumption profile.

The future energy demand of an energy consumer is known, for example, due to a known timing of the energy consumer, such as a timer by a central home control device, and the detected energy demand and / or consumption profile of the energy consumer.

The future estimated energy demand of an energy consumer in the home network results, for example, from the formation of an average of the detected energy demand and / or from an averaging over detected consumption profiles of the energy consumer, which leads to an average profile. In addition to or in addition to the formation of an average value or a mean value profile, other statistical methods are particularly applicable for determining the future estimated energy consumption of an energy consumer.

Forecasting the future energy demand of the one or more energy consumers in the home network is, for example, composed of the estimated future energy needs of the one or more energy consumers in the home network and the known future energy needs of the one or more energy consumers in the home network. Preferably, the prognosis describes a predicted future consumption profile of the one or more energy consumers in the home network, for example a predicted daily consumption profile. For example, the prognosis is a standard load profile modified depending on the recorded consumption profiles. This is advantageous, for example, if only for a part of the one or more energy consumers in the household network a consumption profile can be detected and / or the number of recorded consumption profiles is low, so that the accuracy of the prognosis is limited only as a function of the recorded consumption profiles.

In addition to the energy consumers in the home network, the energy demand is known and / or estimated, there are, for example, other energy consumers in the home network, which have a flexible energy needs. These energy consumers are referred to below as flexible energy consumers. These are, for example, energy consumers that are to be switched on in a certain period of time for a predetermined switch-on period, but whose switch-on time is freely selectable in this period. After switching on, for example, a flexible energy consumer can no longer be switched off in the switch-on period; other flexible energy consumers, for example, can be switched off after being switched on during the switch-on period.

The energy requirement of the flexible energy consumers can be estimated and / or known, for example, from the switch-on time for the switch-on period, preferably the consumption profile of the flexible energy consumers can be estimated and / or known for the switch-on period. A flexible energy consumer, for example, is a washing machine that is designed to perform a specific wash in the course of a day (eg between 10:00 and 18:00). Other examples of such flexible energy consumers are a dryer, a charging station for an electric vehicle or a dishwasher.

Controlling the use of the energy includes, for example, turning on at least one flexible energy consumer at a (future) turn-on time when the estimated and / or known energy needs of the flexible energy consumer and the projected future energy needs of the one or more energy consumers in the home network in the respective home network the turn-on time) of the flexible energy consumer together does not exceed a threshold, preferably when the estimated and / or known power requirements of the flexible energy consumer and the projected future power requirements of the one or more energy consumers in the home network do not commonly exceed a threshold in the corresponding turn-on period. The threshold value is, for example, an average of the energy and / or power provided by the energy generators in the home network in a period before the switch-on time, or the power provided at the switch-on time by the energy generators in the domestic network.

Controlling the use of energy is done, for example, additionally or alternatively in Dependence of a prognosis of the future energy provided by the one or more energy producers in the home network. For example, the forecast describes a limited future period (eg, the next 2, 4, 8, 12, or 24 hours, or 2, 3, 4, 5, 6, or 7 days).

Preferably, the forecast of the future energy provided by the one or more power generators in the home network is a prediction of the time history of the future power provided by the one or more power generators in the home network. A time profile of a service provided is understood, for example, as a generation profile. For example, a generation profile of one or more energy producers describes the time history of the provided power for a day, day generation profile.

For example, the apparatus comprises means for detecting the power and / or power provided by the one or more power generators in the home network and / or detecting a generation profile of the one or more power generators in the home network. For example, feed meters connectable to a central home control device of a home control system are arranged to detect and provide the provided power and / or power and / or the generation profile of one or more power generators in the home network to the central home control device.

Forecasting the future energy provided by the one or more power generators in the home network is, for example, by taking an average of the energy provided and / or averaged over recorded generation profiles over a past period, resulting in a mean profile. In addition to or in addition to the formation of an average value or an average value profile, other statistical methods are also particularly applicable for determining the future energy provided by the energy producers in the household network.

Preferably, the prognosis describes a predicted future generation profile of the one or more energy consumers in the home network, for example a daily generation profile.

Controlling the use of the energy includes, for example, turning on at least one flexible power consumer at a (future) power-on time if the power provided by the one or more power generators in the home network predicted a turn-on period of the flexible power consumer in the corresponding turn-on time of the flexible power consumer is not below, preferably if the predicted in the corresponding turn-on period of the power provided by the one or more power generators in the home network does not fall below a threshold value. The threshold value is composed, for example, of the energy requirement and / or the mean value of the power consumption of the energy consumers in the home network in a past period and a distance value, or the current power consumption of the energy consumers in the home network and a distance value.

Preferably, controlling the use of the energy includes, for example, turning on at least one flexible energy consumer at a (future) power-on time if the energy provided by the one or more power generators in the home network at the corresponding on-time of the flexible energy consumer is the energy provided Sum of the estimated and / or known energy needs of the flexible energy consumer and the predicted future energy needs of the one or more energy consumers in the home network in the corresponding turn-on period, preferably if the predicted power provided by the one or more power generators in the home network in the corresponding turn-on period is the one Sum of the estimated and / or known power requirements of the flexible energy consumer and the predicted future power requirements of the one or more energy consumers consumer in the home network during the relevant switch-on period. For example, the switch-on time of a washing machine may be selected such that the switch-on period of the washing machine is not in a period with a high predicted power requirement, otherwise, for example, the power requirement can not be covered by the power provided by the power generators in the domestic network. Instead, the switch-on time of the washing machine can be set, for example, such that the switch-on period of the washing machine is in a period with a high predicted provided power and, for example, a low predicted power requirement.

Controlling the use of the energy provided, for example, depending on the currently provided by the photovoltaic system power and the current power requirements in the house network. For example, a flexible power consumer may not be turned on, although the power currently provided by the one or more power generators in the home network may reflect the current power requirements of the one or more power consumers in the home network and the flexible power consumer Would provide the sum of the estimated and / or known power requirements of the flexible energy consumer and the projected future power requirements of the one or more energy consumers in the home network in the corresponding one Switch-on period does not cover.

Cases are also possible in which the energy demand and / or power demand of the energy consumers in the household network can not be completely covered by the energy producers in the domestic network. In these cases, controlling the use of energy, for example, allows minimizing the energy supplied by the public power grid into the home network.

Among other things, controlling the use of energy as a function of the forecasts is advantageous in order to allow a flexible adaptation of the energy demand / demand of the energy consumers in the domestic network to the energy / power provided by the energy generators in the domestic network, so that, for example, that of the public Energy network can be minimized in the home network fed energy.

According to one embodiment, the use of the energy comprises at least consuming at least a portion of the energy in the home network and feeding at least a portion of the energy from the home network into a public power grid.

In one embodiment, the use of the energy further includes storing at least a portion of the energy in one or more energy storage means in the home network. An energy storage device is, for example, a heat accumulator, an electrical energy accumulator, a storage heater, for example a night storage heater, a battery (eg an electric vehicle that is temporarily connected to the household network or a photovoltaic system), or a capacitor. The storage of at least a portion of the energy is advantageous, inter alia, to store the energy provided by the energy generators in the home network and to meet a future energy and / or power demand of the energy consumers in the home network.

According to one embodiment, the controlling comprises switching on and / or off at least one energy consumer in the home network, in particular switching on a flexible energy consumer and / or switching off a flexible energy consumer, and / or activating and / or deactivating the feeding of at least a part of Energy from the home network in the public power grid and / or at least partial charging and / or discharging the energy storage device in the home network.

The control is done for example by a home control system. The one or more energy consumers and / or energy storage means are connectable, for example, with a central home control device of the home control system and controlled by this, for example, on and / or off or loadable and / or dischargeable. For example, only some of the one or more energy consumers and / or energy storage devices in the home network are connectable to and / or controllable by the central home control device of the home control system.

For example, the energy consumers can be connected to the household network with the aid of intermediate plug devices, wherein the intermediate plug devices are set up in such a way that the connection of the energy consumers to the domestic network can be switched on and / or off. This means that the intermediate plug devices can, for example, interrupt the energy supply of the energy consumers. The intermediate plug devices can be connected, for example, with the home control device of the home control system and controlled by this. An intermediate plug device comprises, for example, means for detecting the energy requirement, power requirement and / or consumption profile of an energy consumer connected to the household network by the intermediate plug device, for example the intermediate plug device comprises a consumption meter. The intermediate plug devices are formed, for example, as flush-mounted devices and / or as surface-mounted devices. Alternatively or additionally, the energy consumers can be connected to the home control device of the home control system, for example via a house control interface integrated in the energy consumers, and can be controlled by the latter.

The switching on and / or off of an energy consumer in the home network is advantageous, inter alia, to allow a flexible adjustment of the energy consumption (energy consumption) of the energy consumers in the home network to the energy provided by the energy generators in the home network, so that, for example the energy supplied to the public grid can be minimized.

The activation and / or deactivation of the feeding of at least part of the energy from the domestic network into the public power grid is advantageous, inter alia, for feeding in the energy from to adapt surplus energy supplied to energy producers in the home network to a demand for power in the public power grid. For example, the feed-in of surplus power in a period of high power demand in the public power grid may be activated and deactivated in a period of low power demand in the public power grid. Periods of high power demand in the public power grid are, for example, peak load and / or medium load periods. For example, periods of low power demand are base load times. It is also conceivable, for example, that in a period of high power demand in the public power grid, the energy provided by the one or more power generators in the home network will be fully fed into the public power grid, and none of the one or more during a period of low power demand Energy producers in the home network provided energy is fed into the public energy grid.

The at least partially charging and / or discharging of the energy storage means in the home network is advantageous, inter alia, to enable storage of the surplus energy provided by the energy generators in the home network and to meet later energy and / or power demand of the energy consumers in the home network / or to enable a later feed of the stored energy into the public power grid. For example, in a period of low power demand in the public power grid, it is conceivable that the surplus power provided by the one or more power generators in the home network may be stored in the energy storage means and fed into the public power grid during a period of high power demand in the public power grid becomes.

For example, the excess power in the home network may be used to charge the battery of an electric vehicle (temporarily) connected to the home network. The battery of the electric vehicle, for example, the energy stored at least a part of a motor of the electric vehicle available and / or at least part of the stored energy again (for example, later) can deliver to the home network. An electric vehicle is for example a purely electrically operated vehicle or a so-called hybrid vehicle.

According to one exemplary embodiment, the method according to the invention further comprises recognizing the at least one energy consumer and / or energy storage device in the home network, preferably for automatic recognition. For example, the device according to the invention comprises means for detecting the at least one energy consumer and / or energy storage device in the home network.

Detecting an energy consumer and / or energy storage device in the home network is understood in particular to recognize a flexible energy consumer, and / or the type and / or type of the energy consumer and / or energy storage device. One type of energy consumer and / or energy storage device is, for example, the type or device name of the manufacturer. One type of energy consumer and / or energy storage device, for example, summarizes various similar types or devices of one or more manufacturers. Examples of a type of energy consumer are washing machine, dryer, lamp, radiator, radiator, heat exchanger, stove, oven, TV, air conditioning, refrigerator, ventilation and / or freezer.

The recognition of an energy consumer allows, for example, the determination of the known future energy demand and / or the estimated future energy demand of the detected energy consumer in the home network, preferably the determination of a known consumption profile and / or an estimated consumption profile of the detected energy consumer in the home network. For example, for each (recognized) type and / or each (recognized) type, the energy demand and / or consumption profile is stored in a database in the device. In addition, for example, stored in the database, whether it is a flexible energy consumer.

Furthermore, recognizing an energy consumer means, for example, recognizing whether the energy consumer is a flexible energy consumer and / or whether the flexible energy consumer is to be switched on for a specific switch-on period in a future period, for example, if a washing machine will be switched on during the day (eg B. until 16:00) should perform a certain wash.

For example, a user of the device may, through user input, communicate the information necessary for detection to an energy consumer and / or energy storage means in the home network. However, the device is preferably set up to automatically detect an energy consumer and / or energy storage device in the household network. For example, an energy consumer and / or energy storage means of the device may transmit the data necessary for recognition over a connection network.

According to one exemplary embodiment, the recognition of the at least one takes place Energy consumers in the home network at least depending on a detected power requirements, energy needs and / or consumption profile of the at least one energy consumer.

For example, the power requirement, energy demand and / or consumption profile of an energy consumer is characteristic of a particular type and / or type, such that the device is configured, the type and / or type of energy consumer using the sensed power demand, energy demand and / or consumption profile of an energy consumer. For example, in the device, the data (eg, consumption profile data) characteristic of a particular type and / or type is stored in a database for comparison with detected values of an energy consumer.

The power requirement, the energy requirement and / or the consumption profile of an energy consumer can be detected, for example, by means of a corresponding consumption meter and / or sensor in an adapter plug device of a home control system and can be received at the device via a connection network.

According to one exemplary embodiment, controlling the use of the energy further takes place at least as a function of a parameter representative of the current power demand in a public power grid and / or for a prognosis of the future power demand in the public power grid representative parameter.

A parameter representative of the current demand for power in the public power grid is, for example, a high-fare and / or low-rate signal which is received on the home network by a ripple control device of a power supplier of the public power grid. For example, a high rate signal indicates a high demand for power in the public power grid.

In addition, a parameter representative of current and / or future power demand in the public power grid is, for example, the price of power blocks, such as so-called 24 hour blocks, offload blocks, and / or peak load blocks, on a power exchange, such as the Leipzig Power Exchange. A high rate of a power block indicates a high power demand for the corresponding period to which the power block applies. The device is, for example, set up to retrieve the rates for stream blocks on a power exchange via an internet connection.

Among other things, this is advantageous in order to allow an adjustment of the excess power in the home network fed into the public power grid to the demand for power in the public power grid. For example, with a high demand for power in the public power grid, the excess power in the home network can be maximized and energy from the home network can be fed into the public power grid, for example, by turning off flexible power consumption in the home network. In addition, the energy stored in the energy storage means in the home network can be fed from the home network into the public power grid at a high demand for power in the public power grid.

According to one embodiment, the inventive method further comprises receiving at least data, in particular forecast data, from an external data center, wherein the forecast of the future energy provided by the energy generators in the home network and / or the forecast of the future energy demand of the energy consumers in the home network at least Dependence of the data received from the external data center takes place. For example, the device according to the invention comprises means for receiving at least data from an external data center.

For example, the device is configured to receive the data from the external data center via a network connection. In addition, the device is set up, for example, to send data via the network connection to the data center. The network connection is for example a secure connection, preferably an encrypted connection. The network connection is for example a unidirectional or bidirectional connection over a public network, such as a power, telephone or mobile network, a wide area network (WAN) or the Internet. The device comprises, for example, a communication unit which is set up to establish a connection with a data center via such a network, for example a modem. It is also conceivable that the device comprises a communication unit which is set up to establish a connection to an external data center via an external communication module, for example a modem and / or a so-called DSL router, via such a network.

The data received by the data center on the device according to the invention are, in particular, weather data, weather forecast data consumption profile data, generation profile data, performance request data, heading data and / or energy consumer recognition data.

The data center, for example, sends data to the device according to the invention, with the help of which a prognosis of the future energy provided by the generators in the home network and / or a forecast of the future energy needs of energy consumers in the home network is possible. As a result, not all the data required for a prognosis must be stored in the device or captured by the device, but can at least partially be received by the data center. This is advantageous, inter alia, since the accuracy of the prediction can be improved, for example, by additional data not acquired by the device (for example, weather data such as weather forecast data).

For example, the device according to the invention sends consumption profile data of the recorded consumption profile of an energy consumer to the data center. The data center determined on the basis of the consumption profile data type and / or the type of energy consumer and sends the corresponding energy consumer detection data for the energy consumer to the device with the help of a consumer-type or consumer-type forecast of the future energy needs of energy consumers in the home network is possible.

For example, the data center sends weather data to the device according to the invention, with the aid of which a weather-dependent prognosis of the future energy provided by the energy producers in the home network is possible.

The data center sends, for example, forecast data with a prognosis of the future energy provided by the energy generators in the home network and / or the forecast of the future energy demand of the energy consumers in the home network to the device according to the invention. As a result, the device does not have to determine the prognosis itself and not, for example, record the data necessary for the prognosis, but can send it to the data center. This is advantageous, inter alia, if the computing power and / or the storage space in the device is limited.

Furthermore, it is located in the home control system 100 a photovoltaic system 110 that over the counter 108 with the house power network 106 and the public electricity grid 109 is connected such that the electrical energy generated by the photovoltaic system from both the energy consumers 102 to 105 in the house power network 106 consumable as well as in the public power grid 109 can be fed. For example, the excess is not from the energy consumers 102 to 105 in the house power network 106 consumed by the photovoltaic system 110 in the house power network 106 provided energy from the house power network 106 into the public electricity grid 109 fed. The counter 108 is for example a bidirectional counter.

The energy consumers 102 to 104 are over the appropriate radio links 111 to 113 a radio network with the central home control device 101 connected. The energy consumers 102 to 104 are from the central home control device 101 at least on and off via the wireless network.

In this exemplary embodiment, the connection and the switching on and off of the power consumers takes place 102 to 104 via home control interfaces integrated in the energy consumers. In addition, home control interfaces capture energy consumers 102 to 104 the current power requirements and send the recorded power demand data via the wireless network to the central home control device.

However, the intermediate connector device 107 over the radio link 114 of the wireless network with the central home automation device 101 connected. The intermediate plug device is from the central home control device 101 controllable over the radio network so that the adapter plug device can switch on and / or off the power supply of the refrigerator. In addition, the intermediate connector device detects 107 the current power requirement of the refrigerator 105 and sends the acquired power demand data over the radio network to the central home control device. In other embodiments, the refrigerator may 105 for example, have an integrated home control interface.

In addition, the photovoltaic system detects 110 the current of the photovoltaic system in the house electricity network 106 provided (or providable) power and sends the collected performance data over the wireless network to the central home control device 101 ,

The counter 108 is over the radio link 116 with the central home control device 101 connected, for example via one in the counter 108 integrated house control interface. The counter 108 captures the current power requirements of energy consumers 102 to 105 in the home network and currently by the photovoltaic system 110 Power provided in the home network and sends the collected data over the wireless network to the central home control device.

Furthermore, it is conceivable that a charging station for charging the battery of an electric vehicle to the house power network 106 connected. The optional charging station, for example, also via a radio link with the central Home control device 101 connected. For example, from the central home control device 101 controllable whether the battery of an electric vehicle temporarily connected to the charging station is at least partially charged and / or whether stored in the battery of the electric vehicle power in the house power network 106 at least partially in the house electricity network 106 provided. In addition, the charging station detects, for example, the (current) power requirement for charging the battery and sends the recorded power demand data via the wireless network to the central home control device 101 ,

The central home automation device 101 , the energy consumer 102 to 104 , the intermediate connector device 107 , the counter 108 and the photovoltaic system 110 (as well as the optional charging station) form a home control system, such as a RWE SmartHome home automation system. The radio links 111 to 116 form the radio network, for example a CosIP radio network, a WLAN radio network and / or a Bluetooth radio network.

The central home automation device 101 is over the internet 117 with a data center 118 connected and can data from the data center 118 receive and data to the data center 118 send.

2 shows a block diagram of the central home control device according to the invention 101 out 1 , In the 2 shown central home control device 101 includes a processor 1010 , processor 1010 For example, executes program statements stored in program memory 1011 stored, and stores, for example, intermediate results or the like in main memory 1012 , program memory 1011 and / or main memory 1012 can from the processor 1010 used to store data, such as received data, control data and / or forecast data, such as data for controlling the energy consumers 102 to 105 and the photovoltaic system 110 and / or for determining a prognosis of the future generation profile of the photovoltaic system 110 in the house power network 106 and the future consumption profile of one or more of the energy consumers 102 to 105 in the house power network 106 , For example, program memory 1011 a read-only memory (ROM) and main memory 1012 is a volatile or non-volatile memory.

Program statements stored in program memory 1011 In particular, the determination of at least one of the aforementioned forecasts and / or the control of the energy consumers relate to 102 to 105 and the photovoltaic system 110 , The program instructions may be included, for example, by a computer program stored in program memory 1011 is stored or in program memory 1011 has been loaded, for example from a computer program product, in particular a computer-readable storage medium, or via a network.

processor 1010 receives data from radio network module 1013 For example, a CosIP radio network module, a WLAN radio network module and / or a Bluetooth radio network module. To radio network module 1013 are sent via the wireless network to the central home control device 101 sent performance data and power demand data received and sent to the processor 1010 forwarded. In addition, processor can 1010 For example, control commands via radio network module 1013 via the wireless network to the energy consumer 102 to 104 , the intermediate connector device 107 and the photovoltaic system 110 send.

Furthermore receives processor 1010 Data from modem 1014 , To modem 1014 be over the internet 117 from the data center 118 to the central home control device 101 sent data and sent to the processor 1010 forwarded. In addition, processor can 1010 Data via the modem 1014 over the internet 117 to the data center 118 send. Alternatively or additionally, the processor 1010 For example, connectable via a network module with a so-called DSL router, so that on the DSL router via the Internet 117 from the data center 118 to the central home control device 101 sent data and sent to the processor 1010 can be forwarded via the network module.

3a to 3e show examples of consumption profiles of energy consumers 102 to 105 in the home control system 100 out 1 and an example of a production profile of the photovoltaic system 110 in the home control system 100 out 1 ,

In the 3a to 3e Among other things, consumption profiles (or so-called load profiles) are shown which show the time course of the power requirement of one or more of the energy producers 102 to 105 describe schematically over a time period.

The profiles shown are simplified and are merely for the purpose of exemplifying the invention. The profiles shown are, for example, mean consumption or mean generation profiles (averaged profiles or mean value profiles) that result from a plurality of corresponding corresponding consumption or production profiles.

3a shows the averaged time course of the power requirement of the refrigerator 105 over a day, the average daily consumption profile 201 ,

The refrigerator 105 has an at least substantially periodic daily consumption profile, with 2-hour time intervals alternating with at least substantially constant power demand and 2-hour time intervals with no power requirement. In the 2-hour time intervals with the constant power demand compresses the compressor of the refrigerator 105 For example, the coolant, in the 2 h time intervals without power requirements, for example, no compression of the coolant is required.

The daily consumption profile of the refrigerator 105 So it is essentially the same every day, so that in the course of a day with a high probability only minor deviations from the averaged daily consumption profile 201 comes.

3b shows the time course of the power requirement of the lamp 104 over a day, the daily consumption profile 202 , The switch-on periods of the lamp 105 are set via a timer, for example in the central home control device 101 , Besides, the lamp has 104 In the switch-on period, in each case a constant power requirement, so that the daily consumption profile 202 the lamp 104 is known. 3c shows the averaged time course of the power requirement of the stove 103 over a day, the average daily consumption profile 203 ,

The stove 103 is usually turned on during one day at 15:00 and at 19:00 for a turn-on period of usually 1 hour each. The power requirement in the switch-on period at 15:00 is usually lower than the power requirement in the switch-on period at 19:00, for example because fewer cooking plates are switched on.

The usual daily consumption profile of the cooker 103 essentially corresponds to the averaged daily consumption profile in 3b , so that in the course of a day with a high probability only minor deviations from the average daily consumption profile 203 comes. However, on certain days, such as weekends, sick days or public holidays, there may be a high probability of larger deviations from the average daily consumption profile. Therefore, it may be advantageous, for example, to determine an average daily consumption profile for each day of the week and / or holiday (s).

3d shows the time course of the power requirement of the washing machine 102 over a switch-on period, the consumption profile 204 , The switch-on period of the washing machine 102 is 4 hours, whereby the temporal power requirement of the washing machine 102 changed over the 4 hours.

In the first hour of the switch-on period, for example, water will enter the washing machine 102 pumped and heated there, so that the power requirement of the washing machine 102 increased in the first hour. For example, in the second and third hours of the turn-on period, the washing drum is rotated at a low frequency, so that the power requirement of the washing machine 102 decreases. In the fourth hour of the switch-on period, the washing drum is rotated at a high frequency, the laundry is thrown, so that the power requirement of the washing machine 102 increases.

The power requirement of the washing machine 102 Over a switch-on is known, so that the consumption profile 204 is known. However, the exact turn-on time of the washing machine 102 not determined and may, for example, from the central home control device 101 be determined. The washing machine 102 is a flexible energy consumer.

The power or energy requirement of a charging station of the household power network or the connected battery of an electric vehicle, for example, also known for the charging period (switch-on). For example, the charging station can detect the energy requirement and / or the corresponding power requirement in the charging period for (fully) charging the battery. Furthermore, the user can specify at the charging station and / or in the SHC at what time the battery should be (fully) charged, for example on weekdays at 07:30 and on Sundays and public holidays at 09:00. The corresponding data can be transmitted from the charging station to the central home control device. The exact switch-on time of the charging station is thus not fixed and can, for example, from the central home control device 101 be determined so that the battery at the specified time (fully) is charged. The optional charging station is thus a flexible energy consumer.

3e shows the predicted time course of the photovoltaic system 110 in the house power network 106 Provided performance, the forecasted daily generation profile 205 for a specific day. The forecasted daily generation profile 205 is determined, for example, by means of an average daily generation profile and / or weather data, for example weather forecast data.

For example, the photovoltaic system 110 in the house power network 106 from sunrise at 06:00 until sunset at 22:00 power in the house electricity network 106 provide. Between sunset and sunrise, the photovoltaic system 110 in the house power network 106 do not provide any services. The sky should be cloudy in the morning, for example, so that the forecast of the photovoltaic system 110 in the house power network 106 provided power is low until 12:00. In the afternoon and evening, however, the sky should clear up and the sun shine, so the predicted of the photovoltaic system 110 in the house power network 106 provided power is high from 12:00.

Further shows 3e the predicted time course of the power requirement of the cooker 103 , the lamp 104 and the refrigerator 105 , the forecasted daily consumption profile 206 for a specific day. The forecast daily consumption profile 206 consists of the averaged daily consumption profile 201 of the refrigerator 105 , the known daily consumption profile 202 the lamp 104 and the averaged daily consumption profile 203 of the stove 103 ,

In the period from 06:00 to 19:00 and from 20:00 to 22:00, the forecast of the photovoltaic system is sufficient 110 in the house power network 106 provided power to the predicted power requirements of the stove 103 , the lamp 104 and the refrigerator 105 in the house power network 106 cover up. The forecast generation profile 205 covers the forecast consumption profile 206 during this period. Only in the period from 19:00 to 20:00 and after sunset, the forecast of the photovoltaic system is sufficient 110 in the house power network 106 provided power to the predicted power requirements of the stove 103 , the lamp 104 and the refrigerator 105 to cover in the house network.

Further shows 3e a sum 207 the forecasted daily consumption profile 206 and the known consumption profile 204 of the washing machine 102 when the switch-on time of the washing machine is 15:00.

4a shows a flowchart 300 an embodiment of the method according to the invention for controlling the use of the energy provided. The method may, for example, at least partially by the central home control device according to the invention 101 out 1 be executed. For example, the processor performs 1010 out 2 the inventive method with the flowchart 300 out.

In one step 301 the current power provided by the power generators in the home network is detected; and in one step 302 the current power requirement (or consumption) of the energy consumers in the home network is recorded. For example, the current from the photovoltaic system 110 in the house power network 106 provided power from the meter 108 recorded and sent to the central home control device 101 Posted; and in one step 502 becomes the current power demand (or consumption) of the energy consumer 102 to 105 in the house power network 106 from the counter 108 recorded and sent to the central home control device 101 Posted.

In the steps 303 and 304 The forecast daily production profile and the forecasted daily consumption profile are determined for a specific day.

In one step 305 the use of the provided energy is controlled according to the currently detected provided power, the currently detected power demand, the forecasted daily generation profile, and the generated daily usage profile. For example, the use of the photovoltaic system 110 in the house power network 106 provided energy so controlled that, if possible, no energy from the public power grid 109 in the house power network 106 must be fed. If energy from the public energy network 109 in the house power network 106 The use of the energy provided can be controlled in such a way that the energy from the public grid 109 in the house power network 106 Injected energy is minimized.

For example, the switch-on and / or switch-off of flexible energy consumers, such as the washing machine 102 in the house electricity network 106 be determined so that, if possible, no energy from the public power grid 109 in the house power network 106 must be fed. For example, an energy storage device may be in the home power grid 106 be controlled such that the energy storage means in periods with a surplus of power in the house power network 106 is charged and, for example, in periods with a non-photovoltaic system 110 covered power requirement additional power in the house electricity network 106 provides.

For example, it results from the forecasted daily generation profile 205 and the forecasted daily consumption profile 206 that in the period from 19:00 to 20:00 and after sunset the forecast of the photovoltaic system 110 in the house power network 106 provided performance is insufficient to meet the predicted Power requirement in the house power network 106 cover up. Therefore, the central home control device 101 a battery of the photovoltaic system 110 such that the battery is charged during periods of excess power in the household power network and, for example, in the period from 19:00 to 20:00 and / or after sunset additional power in the household power network 106 provides. Alternatively or additionally, a battery of an electric vehicle temporarily connected to an optional charging station of the home control system may be controlled such that the battery is charged in periods with a surplus of power in the household power network and for example in the period of 19:00 to 20:00 and / or after sunset additional power in the house electricity network 106 provides. For example, the optional charging station will be replaced by the central home control device 101 controlled. 4b shows a flowchart 400 an embodiment of the method according to the invention for determining the predicted daily generation profile. The method may, for example, at least partially by the central home control device according to the invention 101 out 1 be executed. For example, the processor performs 1010 out 2 the inventive method with the flowchart 400 out. The flowchart is, for example, in step 303 of the flowchart 300 executed.

In one step 401 the power provided by the energy producers is recorded. For example, that of the photovoltaic system 110 in the house power network 106 provided power and corresponding performance data to the central home control device 101 Posted. The central home automation device 101 receives the performance data and records the time history of the provided service, for example in the form of generation profiles.

In one step 402 becomes the forecasted daily generation profile 205 out 3e depending on the recorded performance data for a specific day.

For example, the central home control device determines 101 from the recorded time history of the photovoltaic system 110 in the house power network 106 provided one or more corresponding averaged daily generation profiles.

For example, the central home control device stores 101 in a database for different weather conditions respectively averaged daily generation profile data. For example, the central home control device receives 101 Weather forecast data for the specific day from the data center 118 and determines the predicted daily generation profile 205 by selecting the daily generation profile data averaged for the corresponding weather situation. Alternatively, the central home control device sends 101 For example, the recorded performance data or generation profile data to the data center 118 which the forecasted daily generation profile 205 determined and corresponding daily generation profile data to the central home control device 101 sends.

4c shows a flowchart 500 an embodiment of the method according to the invention for determining the predicted daily consumption profile. The method may, for example, at least partially by the central home control device according to the invention 101 out 1 be executed. For example, the processor performs 1010 out 2 the inventive method with the flowchart 500 out. The flowchart is, for example, in step 304 of the flowchart 300 executed.

In one step 501 becomes the respective power requirement of the energy producers 102 to 105 in the house power network 106 recorded and corresponding power demand data to the central home control device 101 Posted. The central home automation device 101 receives the power requirement data and records the time course of the respective power requirement, for example in the form of respective consumption profiles.

In one step 502 the energy consumers are recognized in the home network. Alternatively, for example, embodiments are conceivable in which there is no recognition of the energy consumer in the house network.

For example, the central home control device recognizes 101 the type and / or the type of energy consumers 102 to 105 for example, by comparing the recorded consumption profiles with corresponding consumption profile data in one in program memory 1011 stored recognition database. Alternatively or additionally, the central home control device sends 101 the corresponding recorded consumption profile data, for example, to the data center 118 identifying the type and / or type of energy consumers 102 to 105 performs and corresponding detection data to the central home control device 101 sends.

In the exemplary embodiment of the 1 become the energy consumers 103 to 105 for example as a stove 103 , as a lamp 104 and as a refrigerator 105 detected and from the central home control device 101 in determining the forecasted daily consumption profile 206 considered. The energy consumer 105 is used as a washing machine 102 and recognized as a flexible energy consumer.

In one step 503 becomes the forecasted daily consumption profile 206 out 3e intended for a specific day. The forecast daily consumption profile 206 is composed, for example, of the averaged daily consumption profile 201 of the refrigerator 105 , the known daily consumption profile 202 the lamp 104 and the averaged daily consumption profile 203 of the stove 103 ,

For example, the central home control device determines 101 from the recorded time course of the respective power requirement of the energy consumer 102 to 105 in the house power network 106 and the type or type of energy consumers 102 to 105 the corresponding averaged consumption profiles 201 to 204 , For example, information for determining the average consumption profiles may be associated with a recognized type and / or type in the recognition database.

For example, for the refrigerator 105 only the average daily consumption profile 201 This is because a refrigerator has a daily consumption profile that is essentially the same every day.

For the stove 103 on the other hand, for example, a respective averaged daily consumption profile is determined for each day of the week as well as public holidays, holidays and sick days, since larger deviations between the daily consumption profiles are to be expected. The daily consumption profile 203 is one of those averaged daily consumption profiles.

The lamp 104 has a constant power requirement in the switch-on period, for example in the recognition database in program memory 1011 is stored. In addition, the switch-on periods of the lamp 105 For example, set via a timer, for example in the central home control device 101 so that the daily consumption profile 202 the lamp 104 can be determined from the known power requirements and the known switch-on periods.

The power requirement of the washing machine 102 (and for example an optional charging station for an electric vehicle) over a switch-on period (charging period) is also known, for example via an entry in the recognition database in program memory 1011 , However, the exact turn-on time of the washing machine 102 (and the optional charging station) is not fixed and may, for example, from the central home control device 101 be determined because the washing machine 102 (and the optional charging station) is a flexible energy consumer. The washing machine 102 was recognized as a flexible energy consumer and is therefore from the central home control device 101 in determining the predicted daily consumption profile 206 not considered.

4d shows a flowchart 600 an embodiment of the method according to the invention for controlling the use of energy, here by way of example in the form of determining a switch-on for a flexible energy consumer. The method may, for example, at least partially by the central home control device according to the invention 101 out 1 be executed. For example, the processor performs 1010 out 2 the inventive method with the flowchart 600 out. The flowchart is, for example, in step 305 of the flowchart 300 executed.

The determination of the switch-on time of the flexible energy consumer is carried out in such a way that, as far as possible, no energy from the public energy grid has to be fed into the household grid during the switch-on period of the flexible energy consumer. For example, based on the forecasted daily generation profile 205 , the forecasted daily consumption profile 206 and the consumption profile 204 of the washing machine 102 a suitable switch-on time for the washing machine 102 determined such that in the switch-on of the washing machine 102 preferably no energy from the public energy grid 109 in the house power network 106 must be fed.

First, in step 601 Checks whether the currently provided by the energy producers in the home network power covers the current power consumption (or consumption) of energy consumers in the home network. For example, the current from the photovoltaic system 110 in the house power network 106 provided, from the counter 108 recorded and to the central home control device 101 sent power with the current, from the counter 108 recorded and to the central home control device 101 transmitted power requirement (or consumption) of energy consumers 102 to 105 in the house power network 106 compared. If the provided power does not meet the power requirement, then step 601 repeated.

When the provided power meets the power requirement, it will step in 602 Checks whether a flexible energy consumer is waiting to be switched on. If no flexible energy consumer is waiting to be switched on, then step 601 repeated.

For example, it is recognized (for example, in step 502 from flowchart 500 ) that the washing machine 102 do a wash should and on turning on (for example, by the home control device 101 ) is waiting. For example, the central home control device recognizes 101 that the washing machine 102 was loaded with laundry and should perform a wash. For example, the washing machine sends 102 corresponding data about the radio link 111 to the central home control device 101 , When the washing machine 102 not directly via a radio link with the central home control device 101 connectable and controllable by this, but the connection and the control is done via a Zwischensteckervorrichtung, for example, the intermediate connector device could recognize that the washing machine 102 started by the user. For example, the intermediate plug device could have an (increased) power requirement of the washing machine 102 determine the power supply of the washing machine 102 then interrupt and corresponding data to the central home control device 101 send.

For example, a washing machine may be powered up (for example, by the user or the central home control device 101 ) are no longer turned off by the central home control device. By contrast, other flexible energy consumers can be switched off after being switched on by the central home control device, for example a dryer or possibly an optional charging station for an electric vehicle. In this case, the switch-on period could possibly be interrupted. Such information may be associated with a recognized type and / or type in the recognition database.

When a flexible energy consumer turns on by the central home automation device 101 Waiting, will step in 603 the sum of the predicted daily consumption profile and the consumption profile of the flexible energy consumer is formed at the present time, assuming that the flexible energy consumer is turned on at the current time, so that the sum is formed at least for the corresponding switch-on period of the flexible energy consumer, for example the next 4 hours. Furthermore, in step 603 checking whether the sum of the predicted daily consumption profile and the consumption profile of the flexible energy consumer is covered by the predicted daily generation profile in the corresponding switch-on period (for example, an interrupted or uninterrupted switch-on period, which is determined by the runtime of the flexible energy consumer) Thus, the operation of the flexible energy consumers in the corresponding switch-on without energy from the public power grid is possible.

For example, the sum of the forecasted daily consumption profile 206 and the consumption profile 204 of the washing machine 102 in the corresponding switch-on period of the washing machine 102 educated. The sum formed corresponds to the time course of the predicted total power requirement of the energy consumers 102 to 105 in the house power network 106 when the washing machine 102 at the current time for the switch-on is turned on.

If the forecasted daily generation profile does not cover the sum of the forecasted daily consumption profile and the consumption profile of the flexible energy consumer in the corresponding switch-on period, then step 602 repeatedly and it is checked whether another flexible energy consumer to turn on (for example, by the central home control device 101 ) is waiting. Alternatively, for example, step 601 be repeated if the forecasted daily generation profile does not cover the sum of the projected daily consumption profile and the consumption profile of the flexible energy consumer in the corresponding switch-on period, for example if no further flexible energy consumer is waiting to be switched on.

If the forecasted daily generation profile covers the sum of the forecasted daily consumption profile and the consumption profile of the flexible energy consumer in the corresponding switch-on period, the flexible energy consumer will be in step 604 switched on. Subsequently, the forecasted daily consumption profile is supplemented by the consumption profile of the flexible energy consumer in the corresponding switch-on period and step 602 repeated.

As it turned out 3e gives, the washing machine can 102 For example, only be turned on at 15:00, without any energy from the public power grid 109 in the house power network 106 must be fed. The corresponding to the consumption profile 204 of the washing machine 102 supplemented daily consumption profile 207 is in 3e hatched shown.

For example, if the requirement can not be met within a given time period, for example within one day, then the flexible energy consumer will be powered on independently of the currently detected provided power, the currently sensed power demand, the forecasted daily generation profile, and the generated daily usage profile , Alternatively or additionally, the flexible energy consumer can be switched on, for example, in such a way that the energy fed into the household network from the public power grid is at least minimized. Alternatively or additionally, for example, a query can be made at the user, whether the switching is to be moved (and for example, for how long it should be moved).
