Description

  The present invention relates to a power generator control system, a power generator control method, a program, and a recording medium that match a power load of a home electric appliance with a power generation amount of a power generator.

  When a generator such as a fuel cell, a gas engine, or a gas turbine is introduced into a general household, the problem is the magnitude of fluctuations in power load in the general household. These generators can be expected to improve the overall efficiency of energy use by effectively using waste heat together with the generated power. However, it takes a long time to reach the desired amount of power generation from startup, and it is also used in ordinary households. Power generation follow-up performance against load fluctuations of household appliances to be used is not good.

  Under such circumstances, as one method for following the power load fluctuation of the power equipment such as an air conditioner, conventionally, the power load fluctuation is based on the fluctuation of the power equipment load before giving an output control command to the generator. The command value for making it follow is output to the generator. In the case of this method, for example, there is a change in the control of the power equipment performed by the user, it appears as a load fluctuation, and it is determined that the change is not temporary. Output control is performed on the machine side (see, for example, Patent Document 1).

  When the operation of the generator is judged to be based on the fluctuation of the household power load up to the present time and simply followed as in the conventional example, since the fluctuation appears in the power load, it is reflected as a response command gradually. There will be a delay in the reactivity as a response command to fluctuations in the power load. Therefore, when the power load tends to increase, there is a problem that the power generation amount is insufficient, and that commercial power is purchased from an electric power company or the like every time, so that there is no cost merit.

  In order to deal with the problem of reactivity as a response command to the above power load fluctuation, as another method for power load fluctuation, the current power load fluctuation is predicted from the past data of electric power fluctuation of home appliances. There has been a method of operating the generator based on the prediction result (see, for example, Patent Document 2).

JP 2002-319419 A JP 2003-134888 A

  However, in the method described in Patent Document 2, the power load fluctuation of the home appliance is caused by irregular / irregular activities of a person who handles the fluctuation, and it is difficult to accurately predict the fluctuation.

  Moreover, even if it can be predicted accurately, the generator such as a fuel cell as described above essentially has a problem that the power generation followability is not good with respect to load fluctuations of household appliances in general households. As will be described below, load fluctuations exceeding the power generation follow-up performance of the generator cannot be dealt with in the end, resulting in no cost merit.

  That is, FIG. 6 is an example of an air conditioner. For example, the maximum power / rated power of the air conditioner is 690 W / 350 W for the 2.2 kW type, 780 W / 420 W for the 2.5 kW type, and 900 W / 475 W for the 2.8 kW type. It is. FIG. 6 shows a power consumption trend at the time of startup of the 2.5 kW type. As can be seen from FIG. 6, the current air conditioner is generally up to about 1 minute.

  On the other hand, as a generator, for example, the load accelerating performance of a fuel cell is 1 W / s for both output increase and decrease with the latest target specifications. Therefore, it takes 5 minutes to increase the output up to 300W, and 10 minutes up to 600W. Even if it can be predicted accurately in anticipation of the load fluctuation as described above, the load fluctuation exceeds the power generation follow-up performance of the generator. Can't cope with after all.

  The present invention solves the problems of the conventional power load tracking method of the conventional generator control system, and prevents the purchase of expensive commercial power from the power company as much as possible against the power load fluctuation of home appliances. Another object of the present invention is to provide a generator control system, a generator control method, a program, and a recording medium that are excellent in reactivity as a response command and that can output a command value in which a power load value is predicted more accurately.

(Embodiment 1)
FIG. 1 is a configuration diagram of a generator control system in the present embodiment.

  In FIG. 1, the generator 100 includes a fuel cell, a gas turbine, a gas engine, and the like. The power generation measuring unit 110 is a device that is installed on the output line of the generator 100 and measures the power generation of the generator 100. The generated power here is instantaneous power generated by the generator 100.

  The device 200 is a general device used at home, such as an air conditioner, a heating device, and a lighting device, and the device power consumption measuring unit 210 is a device that measures the power consumption of the device 200. There are a plurality of devices 200 and device power consumption measuring units 210, respectively. Both the power generation measuring unit 110 and the device power consumption measuring unit 210 use a power sensor or the like.

  The power generated by the generator 100 is supplied to and consumed by the device 200 via a household distribution board and power line.

  Further, the generator control system in the present embodiment is also connected to a commercial power system 380 for supplying power by an electric power company as shown in FIG. 1, and the power supplied from the commercial power system 380 is also It is supplied to and consumed by the device 200 via a home distribution board or power line.

  The control unit 300 includes a generator control unit 310, a device operation control unit 320, a device operation detection unit 330, and a power information display unit 390. The control unit 300 is physically composed of a CPU, a memory, and a communication interface.

The generator control unit 310 has a communication interface that connects to a communication medium such as RS-232C, dedicated line, wireless, and power line, and is connected to the generator 100 via the communication medium. The generator control unit 310 is a device that creates and sends out a control signal for performing a start / stop command, output change, and the like for the generator 100.

  The device operation control unit 320 is a device that controls the device 200, and is connected to the power generation measurement unit 110, the device 200, and the device power consumption measurement unit 210 via a communication medium such as a dedicated line, a wireless line, and a power line. Has been. Note that when the power generation measured by the power generation measuring unit 110 is processed by the device operation control unit 320, the A / D conversion may be performed by either the power generation measurement unit 110 or the device operation control unit 320. .

  Similarly, when calculating the power consumption of the device 200 measured by the power consumption measurement unit 210 by the device operation control unit 320, A / D conversion is performed by the device operation control unit 320 even if it is performed by the power consumption measurement unit 210. Can be either. The device operation control unit 320 is a device that creates and sends a control signal for performing start / stop, setting change, and the like to the device 200.

  The device operation detection unit 330 is connected to the device 200 via a communication medium such as RS-232C, dedicated line, wireless, and power line, and detects the setting state of the device 200. For example, in the case of an air conditioner, the set state is set parameters such as cooling, heating, temperature, and breeze. As a method for acquiring the setting state of the device 200, that is, the setting parameter, the device operation detection unit 330 periodically issues a setting state acquisition request to the device 200 to acquire the setting state, or the setting state of the device 200 is changed. Then, when the device 200 voluntarily notifies the device operation detection unit 330 or when the device 200 is changed in the setting state by the user remote controller, the device operation detection unit intercepts the remote control signal and sets the setting state. The method of acquiring

  Note that the device operation control unit 320 and the device operation detection unit 330 share the setting state information of the device 200, and when the device operation detection unit 330 cannot directly acquire the setting state of the device 200, the device operation control unit It is also possible to acquire the latest control state sent from 320 to the device 200 and recognize the setting state of the device 200.

  The power information display unit 390 is used through the interface screen to indicate that energy saving control is being performed, the operating status of the device 200 under control, the time transition of the actual or predicted power consumption of the device 200, and the estimation of power cost reduction through control. It is a device that presents control information to the user in an easy-to-understand manner.

  Next, the operation of the present embodiment configured as described above will be described. Here, a case where the device 200 is an inverter air conditioner (hereinafter referred to as an air conditioner 200) will be described.

  Assume that the generator 100 is operating with a constant power generation. It is assumed that the devices 200 other than the air conditioner 200 operate by receiving the power generated from the generator 100 and are not supplied with commercial power from the commercial power system 380.

  As described above, when the user operates the air conditioner 200 while the air conditioner 200 is stopped while the generator 100 is operating at a constant power generation, the device operation detection unit 330 detects the setting state, that is, the setting parameter. . And the apparatus driving | operation detection part 330 outputs the information that the air conditioner 200 was turned ON with the setting parameter to the generator control part 310. FIG. Receiving this, the generator control unit 310 outputs to the generator 100 a control signal for increasing the generated power of the generator 100 to, for example, the maximum output.

  When the generator 100 receives the control signal from the generator control unit 310, the generator 100 starts an operation for increasing the generated power to the maximum output, for example, according to the control signal. However, in general, a time of several minutes is required for the generator 100 to increase its output. Accordingly, the device operation control unit 320 monitors the rising portion of the power generation of the generator 100 obtained from the power generation measuring unit 110 and controls the operation of the air conditioner 200 so that the power consumption of the air conditioner 200 is matched with the rising portion of the power generation. .

  Specifically, for example, when the air conditioner 200 is turned on in the setting state (setting parameter) of the operation mode “cooling”, the set temperature “25 ° C.”, and the air volume “strong”, the output of the generator 100 starts to increase. At the same time, the device operation control unit 320 ignores the setting condition (setting parameter) and forces the air conditioner 200 to reduce power consumption such as “cooling”, set temperature “27 ° C.”, and air volume “fine”. Control is performed so that the increase amount does not exceed the increase amount of the power generation of the generator 100.

  Thereafter, the device operation control unit 320 gradually monitors the power consumption of the air conditioner 200 obtained from the device power consumption measurement unit 210 while gradually preventing the power generation of the generator 100 from being exceeded. The air conditioner 200 is controlled to approach “25 ° C.” and the air volume “strong”.

  As described above, when the generator control system according to the first embodiment detects that the user has changed the setting on the device side such as the air conditioner 200, the generator control system controls the output of the generator 100 according to the content of the setting change. . Therefore, since control is performed in accordance with a setting change on the device side such as the air conditioner 200, it is possible to output a command value that is excellent in reactivity and more accurately predicts the power load value as a response command to the load fluctuation of the device. .

  The control of the device operation control unit 320 will be described in detail below.

  When the air conditioner 200 is turned on in the setting state (setting parameter) of the operation mode “cooling”, the set temperature “25 ° C.”, and the air volume “strong”, the generator 100 follows the control signal from the generator control unit 310. For example, even when the operation for increasing the generated power to the maximum output is started, it takes time of the order of several minutes as described above until the generated power reaches the maximum output.

  Accordingly, as soon as the generator 100 starts the operation to increase the output, the total power consumption of the air conditioner 200 and the devices 200 other than the air conditioner 200 exceeds the generated power of the generator 100, and the air conditioner 200 The power to be supplied to the etc. will be insufficient. Therefore, commercial power is also supplied from the commercial power system 380 to the air conditioner 200 or the like in order to compensate for the shortage of power.

  On the other hand, the power generation measurement unit 110 monitors the power generation of the generator 100, and the device power consumption measurement unit 210 measures the power consumption of the air conditioner 200 and the like. The equipment operation control unit 320 and the like monitor the increase in power consumption of the air conditioner 200 measured by the power generation measurement unit 110 and the increase in power generation of the generator 100, and the following (1) to (3) Control.

(1) Control when the increase in power consumption of the air conditioner 200 after the start of operation of the air conditioner 200 exceeds the increase in power generation of the generator 100 The device operation control unit 320 is an air conditioner measured by the device power consumption measurement unit 210. When the increase in power consumption of 200 exceeds the increase in power generation of the generator 100, control is performed so that the increase in power consumption of the air conditioner 200 is reduced.

  That is, when the increase in power consumption of the air conditioner 200 exceeds the increase in power generation of the generator 100, the device operation control unit 320 determines that the increase in power consumption of the air conditioner 200 is the power generation of the generator 100. The set temperature is increased by 1 ° C. in the set state (set parameter) of the air conditioner 200 until it does not exceed the increased amount of. When the increase in power consumption of the air conditioner 200 does not exceed the increase in power generation of the generator 100, the air conditioner 200 or the like can be operated only by the power generation of the generator 100, so the commercial power system 380 Supply of commercial power from is stopped.

  For example, as described above, when the air conditioner 200 is turned on in the setting state (setting parameter) of the operation mode “cooling”, the set temperature “25 ° C.”, and the air volume “strong”, the increase in power consumption of the air conditioner 200 is increased. When the amount of increase in the power generation of the generator 100 is exceeded, the device operation control unit 320 controls the setting state (setting parameter) of the air conditioner 200 so that the power consumption of the air conditioner 200 decreases. For example, the air conditioner 200 is controlled to increase the set temperature by 1 ° C., that is, to change the set temperature to “26 ° C.”. The air conditioner 200 operates by changing the set temperature to “26 ° C.” under the control of the device operation control unit 320. If the increase in power consumption of the air conditioner 200 exceeds the increase in power generation of the generator 100 even when the set temperature of the air conditioner 200 is changed to “26 ° C.”, the device operation control unit 320 further The setting state (setting parameter) of the air conditioner 200 is controlled so that the power consumption of the air conditioner 200 is reduced. For example, the air conditioner 200 is controlled to increase the set temperature by 1 ° C., that is, to change it to “27 ° C.”.

  Since the set temperature of the air conditioner 200 has been changed from “25 ° C.” to “27 ° C.”, the increase in power consumption of the air conditioner 200 is reduced, and the increase in power consumption of the air conditioner 200 is the amount of power generated by the generator 100. It will be less than the increase. Therefore, in this case, since the air conditioner 200 can be operated only by the power generated by the generator 100, the supply of the commercial power from the commercial power system 380 is stopped.

(2) Control when the increase in the power generation of the generator 100 after the start of the operation of the air conditioner 200 is larger than the increase in the power consumption of the air conditioner 200 by a predetermined value or more. When the amount of increase in the generated power becomes larger than the amount of increase in the power consumption of the air conditioner 200 by a predetermined value or more, control is performed so that the amount of increase in the power consumption of the air conditioner 200 becomes larger.

  That is, when the increase in the power generation of the generator 100 is greater than the increase in the power consumption of the air conditioner 200 by a predetermined value or more, the device operation control unit 320 increases the increase in the power generation of the generator 100. The set temperature of the setting state (setting parameter) of the air conditioner 200 is decreased by 1 ° C. until the power consumption of the air conditioner 200 does not increase by a predetermined value or more.

  For example, while the air conditioner 200 is operated in the setting state (setting parameter) of the operation mode “cooling”, the set temperature “27 ° C.”, and the air volume “strong”, the generated power of the generator 100 gradually increases with time. To rise. When the increase in the power generation of the generator 100 is greater than the increase in the power consumption of the air conditioner 200 by a predetermined value or more, the power generation of the generator 100 exceeds the power consumption of the air conditioner 200. The control unit 320 controls the air conditioner 200 so that the power consumption of the air conditioner 200 increases and approaches the setting of the user. For example, the air conditioner 200 is controlled to change the set temperature from “27 ° C.” to “26 ° C.” in the set state (setting parameter) of the air conditioner 200. The air conditioner 200 operates by setting the set temperature to “26 ° C.” in the set state (setting parameter) of the air conditioner 200 according to the control of the device operation control unit 320.

  Since the set temperature of the setting state (setting parameter) of the air conditioner 200 is changed from “27 ° C.” to “26 ° C.”, the increase in power consumption of the air conditioner 200 increases. However, the power generation of the generator 100 has also increased since a certain amount of time has elapsed since the start of the operation for increasing the power generation to the maximum output. Accordingly, the increase in power consumption of the air conditioner 200 is smaller than the increase in power generation of the generator 100. Therefore, the generator 100 can supply the power consumed by all the devices 200 other than the air conditioner 200 and the air conditioner 200. Therefore, the commercial power system 380 maintains a state where commercial power is not supplied.

  However, when the set temperature of the setting state (setting parameter) of the air conditioner 200 is changed from “27 ° C.” to “26 ° C.”, the increase in the power consumption of the air conditioner 200 is different from the above. There may also be cases where the increase in generated power is exceeded. When such a case occurs, the generator 100 alone cannot supply the power consumed by the air conditioner 200 or all of the devices 200 other than the air conditioner 200. Therefore, the shortage of commercial power is supplied from the commercial power system 380 to the air conditioner. 200 or the like. In this case, the device operation control unit 320 performs the control described in (1). That is, the device operation control unit 320 controls the air conditioner 200 so that the set temperature of the set state (setting parameter) of the air conditioner 200 is returned from “26 ° C.” to “27 ° C.”. The air conditioner 200 operates by setting the set temperature to “27 ° C.” in the set state (setting parameter) of the air conditioner 200 according to the control of the device operation control unit 320. Since the set temperature of the setting state (setting parameter) of the air conditioner 200 is returned from “26 ° C.” to “27 ° C.”, the increase in power consumption of the air conditioner 200 becomes small. Therefore, the increase in power consumption of the air conditioner 200 is smaller than the increase in power generation of the generator 100. Therefore, the generator 100 can supply power consumed by all the devices 200 other than the air conditioner 200 and the air conditioner 200, so that the supply of commercial power from the commercial power system 380 is stopped.

  Further, when the increase in the generated power of the generator 100 is greater than the increase in the power consumption of the air conditioner 200 by a predetermined value or more, the set temperature (setting parameter) of the air conditioner 200 is changed from “27 ° C.”. Even when the temperature is changed to “26 ° C.”, the increase in the generated power of the generator 100 may be larger than the increase in the power consumption of the air conditioner 200 by a predetermined value or more. In such a case, control may be performed so that the set temperature of the set state (set parameter) of the air conditioner 200 is further lowered by 1 ° C. That is, the set temperature of the setting state (setting parameter) of the air conditioner 200 is incremented by 1 ° C. until the increase in the generated power of the generator 100 does not exceed a predetermined value more than the increase in the power consumption of the air conditioner 200. What is necessary is just to perform control to reduce.

(3) Control when the setting state (setting parameter) of the air conditioner 200 falls within the target setting state (setting parameter) Further, while the device operation control unit 320 is performing the above-described control, the air conditioner 200 When the set state matches the set state set by the user, when the set temperature of the set parameters reaches the target set temperature “25 ° C.”, the device operation detection unit 330 detects that, Notify the generator control unit 310. The generator control unit 310 controls the generator 100 so as to operate at a constant output with the generated power at the time point notified from the device operation detection unit 330. The generator 100 starts rated operation according to the control from the generator control unit 310.

  By performing the controls (1) to (3), the device operation control unit 320 and the like can operate the air conditioner 200 without receiving commercial power from the commercial power system 380 as much as possible.

  In addition, when the above control is performed, the air conditioner 200 is operated in a setting state (setting parameter) different from the setting state (setting parameter) actually set by the user, which may cause inconvenience for the user. .

  Therefore, for example, the power information display unit 390 is in the energy saving control state (the state in which the above control is performed), the operation state of the device 200 by the control, the actual measurement value of the power consumption of the device 200, and the power cost reduction by the control. The control information is presented to the user in an easy-to-understand manner through the interface screen.

  As a result, the user can set energy-saving operation of the device 200 according to the time zone and lifestyle, and even if inconvenience is felt, the current operation state of the device 200 is disclosed, so the user's A sense of incongruity with control can be reduced.

  As described above, according to the first embodiment, when the user changes the setting parameter of the device 200, the device operation control unit 320 determines that the power consumption of the device 200 obtained from the device power consumption measurement unit 210 is as follows. Since the controllable factor of the device 200 is controlled so as not to exceed the generated power of the generator 100 that is obtained from the generated power measurement unit 110, the purchase of commercial power due to the rapid increase in the power consumption of the device 200 is avoided. It is possible to provide a generator control system that reduces the cost merit of introducing a generator.

  Although it is desirable that the power consumption of the device 200 does not exceed the power generation of the rising generator 100, it may be designed so as not to exceed a little.

(Embodiment 2)
Next, a second embodiment will be described. In the first embodiment, the power consumption of the device 200 temporarily exceeds the generated power of the generator 100 under the control of the device operation control unit 320, and it is necessary to temporarily receive commercial power supply from the commercial power system 380. A case occurred. On the other hand, in the second embodiment, the power consumption of the device 200 is predicted, and the setting result (setting parameter) of the device 200 is controlled using the prediction result, thereby comparing the device with the first embodiment. The generator control system will be described in which the power consumption of 200 does not exceed the power generated by the generator 100, and accordingly, the supply of commercial power from the commercial power system 380 is less than in the first embodiment.

  FIG. 2 is a configuration diagram of the generator control system in the present embodiment.

  In FIG. 2, the device power consumption measuring unit 210 does not exist as compared with the first embodiment, and instead, a power consumption predicting unit 340 and an environment measuring unit 260 are provided.

  The power consumption prediction unit 340 is a device that predicts the power consumption of the device 200. The environment measurement unit 260 is a device that measures the temperature, humidity, outside temperature, and the like of the room where the device 200 is set. The environment measurement unit 260 may be a measurement unit built in the device 200. Since other configurations are the same as those of the first embodiment, description thereof is omitted.

  Next, the operation of the present embodiment configured as described above will be described. Here, a case where the device 200 is an inverter air conditioner (hereinafter referred to as an air conditioner 200) will be described.

  When the user turns on the air conditioner 200 while the generator 100 is operating at a constant power generation and the air conditioner 200 is stopped, the device operation detection unit 330 detects this, and the power consumption prediction unit 340 detects the current setting state of the air conditioner 200. Is output. Here, when the total power consumption of the air conditioner 200 or the like exceeds the power generation of the generator 100 until the user turns on the air conditioner 200 and then controls the air conditioner 200 described below, Since power to be supplied to the air conditioner 200 and the like is insufficient, commercial power is supplied from the commercial power system 380 to compensate for the shortage.

  The power consumption prediction unit 340 predicts the power consumption when the air conditioner 200 is operated in the set state. Specifically, the outside temperature and the room temperature of the room in which the air conditioner 200 is installed are acquired from the environment measurement unit 260, and the difference between the set temperature and the outside air temperature, the difference between the set temperature and the room temperature, and the air volume are calculated. Prediction is performed using a regression line (or regression curve) as a variable, a power consumption prediction model such as a neural network that receives room temperature, outside temperature, set temperature, and air volume as input.

  That is, the power consumption predicting unit 340 holds a control algorithm for determining control parameters (such as fan rotation frequency) of the air conditioner and a power consumption table when operating with the determined control parameters, and the outside air temperature and the air conditioner are determined. Air conditioning control is simulated from the temperature data of the installed room, and instantaneous power consumption is predicted.

  As another method, there is a prediction method using an interpolation function such as a neural network. In other words, when the device is an air conditioner, the instantaneous instantaneous power consumption is predicted using a neural network that is trained to output power consumption when environmental conditions (outside temperature, room temperature) and set temperature are input in advance. To do.

  The generator control unit 310 outputs a control signal to the generator 100 so that the power consumption of the device 200 predicted by the power consumption prediction unit 340 is set as a power generation target of the generator 100. At that time, the device operation control unit 320 performs the following control.

  When the generator 100 starts to increase the generated power according to the control signal from the generator control unit 310, the device operation control unit 320 uses the generated power of the generator 100 obtained by the generated power measurement unit 110 to be consumed by the air conditioner 200. The device 200 is controlled so that the power does not exceed. For example, when the air conditioner 200 is turned on with the operation mode “cooling”, the set temperature “25 ° C.”, and the air volume “strong” and the set parameter is set, the device operation control unit 320 first sets the air conditioner 200 to the set temperature “27 ° C.”. ”, Make the air flow“ fine ”.

  As described above, if the setting state (setting parameter) of the air conditioner 200 is controlled so as not to exceed the power generation of the generator 100, the air conditioner 200 can be operated only by the power generation of the generator 100. The supply of commercial power from the power system 380 is stopped.

  Then, the device operation control unit 320 monitors the power generation obtained from the power generation measurement unit 110 and gradually brings the air conditioner 200 closer to the user setting. Specifically, the power consumption when the set temperature and the air volume are virtually changed in several ways is predicted by the device power consumption prediction unit 340, and the settings of the air conditioner 200 are set in order from the combination with the smaller predicted power consumption value. Switch over. For this purpose, various types of setting states, that is, combinations of setting parameters and measured environmental parameters, and the relationship between estimated power consumption corresponding to the combinations are prepared in advance as data. The setting state of the air conditioner 200 is sequentially switched using.

  That is, the device operation control unit 320 monitors the power generation obtained from the power generation measurement unit 110, and is the most targeted setting state in a setting state in which the power consumption of the air conditioner 200 does not exceed the power generation being monitored. The setting state of the air conditioner 200 is switched to a setting state close to (setting parameter). Assuming that the current setting state (setting parameters) of the air conditioner 200 is operating in the operation mode “cooling”, the setting temperature “27 ° C.”, and the air volume “fine”, the device operation control unit 320 measures and sets the setting parameters. A setting state that does not exceed the monitored power generation by using data indicating the relationship between the combination of environmental parameters and the estimated power consumption corresponding to the combination, and the most targeted setting state (setting parameter) Control is performed to change the setting state of the air conditioner 200 to a setting state close to.

  Here, whether or not the target setting state (setting parameter) is close is determined by using an evaluation function for obtaining a distance between the air conditioner 200 setting state (setting parameter) and the target setting state (setting parameter). It can be judged. That is, in this evaluation function, the smaller the value of the evaluation function, the closer the distance between the setting state (setting parameter) and the target setting state (setting parameter), and the setting state (setting parameter) of the air conditioner 200 is. This indicates that the target setting state (setting parameter) is close. As such an evaluation function, for example, when the operation mode is “cooling”, if the setting state (setting parameter) other than the operation mode is represented by a set of (set temperature, air volume), the following number An evaluation function h (set temperature, air volume) such as 1 can be used.

(Equation 1)
h (Set temperature, air volume) = (A × ((Set temperature) − (Target set temperature)) ² + B × ((Air volume) − (Target air volume)) ² ) ^1/2
However, A and B are constants, and in order to determine whether the current setting state (setting parameter) is close to the target setting state (setting parameter), determination is made by weighting either the set temperature or the air volume. It is determined in advance according to whether or not to do so. For example, when the set temperature is emphasized and the air volume is not so important, the constant A may be set to a large value and the constant B may be set to a small value. When the evaluation function h (set temperature, air volume) is calculated according to Equation 1, the set temperature is expressed by a numerical value indicating the temperature in Celsius, and the air volume is also 1 for fine, 2 for weak, 3 for strong. Is expressed as a numerical value such as 4.

  When the power generation of the generator 100 increases with time and then reaches the target power generation, the device operation control unit 320 performs the above control, so that the air conditioner 200 has a target setting state (setting). Parameter), that is, the air conditioner 200 is operated in the operation mode “cooling”, the set temperature “25 ° C.”, and the air volume “strong”.

  In addition, when the above control is performed, the air conditioner 200 is operated in a setting state (setting parameter) different from the setting state (setting parameter) actually set by the user, which may cause inconvenience for the user. .

  Therefore, for example, the power information display unit 390 is in the energy-saving control (the state in which the above control is performed), the operation status of the device 200 by the control, the time transition of the predicted value of the device 200, and the power cost reduction by the control The control information is presented to the user in an easy-to-understand manner through the interface screen.

  As a result, the user can set energy-saving operation of the device 200 according to the time zone and lifestyle, and even if inconvenience is felt, the current operation state of the device 200 is disclosed, so the user's A sense of incongruity with control can be reduced.

  As described above, according to the second embodiment, when the user changes the setting state of the device 200, the device operation control unit 320 simulates the power consumption of the device 200 to generate the power generation measuring unit 110. Since the device 200 is controlled so as not to exceed the rising portion of the generated power of the generator 100 obtained from the same as in the first embodiment, the purchase of commercial power due to the rapid increase in power consumption of the device 200 is reduced, and the generator is introduced. In addition, since a power sensor for measuring the power consumption of the device 200 is not required to be installed, a relatively inexpensive generator control system can be provided.

  In addition, this embodiment is an essential configuration in a closed power supply system that does not assume the purchase of commercial power.

  In the present invention, the environment measuring unit 260 is not necessarily provided, and the power consumption may be predicted based on only one or a plurality of setting parameters of the air conditioner 200.

(Embodiment 3)
Next, Embodiment 3 will be described. In the second embodiment, the case where the power consumption of the device 200 is predicted and the setting state (setting parameter) of the device 200 is controlled using the prediction result has been described. However, in the third embodiment, the second embodiment is described. In addition to the above case, a power generator control system that can further measure the power consumption of the device 200 and improve the prediction accuracy of the power consumption of the device 200 using the measurement result will be described.

  FIG. 3 is a configuration diagram of the generator control system in the present embodiment.

  In FIG. 3, a power consumption measuring unit 210 is present as compared to the configuration of FIG. Since other configurations are the same as those of the second embodiment, the description thereof is omitted.

  Next, the operation of the present embodiment configured as described above will be described with a focus on differences from the second embodiment. Here, a case where the device 200 is an inverter air conditioner (hereinafter referred to as an air conditioner 200) will be described.

  When the user turns on the air conditioner 200 while the generator 100 is operating at a constant power generation and the air conditioner 200 is stopped, the device operation detection unit 330 detects this, and the power consumption prediction unit 340 detects the current setting state of the air conditioner 200. Is output. The power consumption prediction unit 340 predicts the power consumption when the air conditioner 200 is operated in the set state. For the prediction of the power consumption of the air conditioner 200, the power consumption prediction model described in the second embodiment is used.

  The generator control unit 310 outputs a control signal to the generator 100 so that the power consumption of the device 200 predicted by the power consumption prediction unit 340 is set as a power generation target of the generator 100.

  When the generator 100 starts to increase the generated power, the device operation control unit 320 does not exceed the power consumption of the air conditioner 200 obtained by the power consumption measuring unit 210 with respect to the power generated by the power generation measuring unit 110. The device 200 is controlled. Even when the air conditioner 200 is turned on in the operation mode “cooling”, the set temperature “25 ° C.”, and the air volume “strong”, for example, the device operation control unit 320 first sets the air conditioner 200 to the set temperature “27 ° C.” and the air volume “fine”. To drive.

  Then, the power generation obtained from the power generation measurement unit 110 and the power consumption of the air conditioner 200 obtained from the power consumption measurement unit 210 are monitored, and when there is a surplus in the power generation, the air conditioner 200 is gradually brought closer to the user setting. In order to gradually bring the power consumption of the air conditioner 200 closer, specifically, the set temperature and the air volume are virtually changed in several ways, and the power consumption at that time is predicted by the device power consumption prediction unit 340. It switches in order from the combination of the setting with the small predicted value of power consumption. That is, as in the second embodiment, various types of setting states, that is, combinations of setting parameters and measured environmental parameters, and the relationship between estimated power consumption corresponding to the combinations are prepared in advance as data. Then, using these data, the setting state of the air conditioner 200 is sequentially switched. That is, in the present embodiment, the power consumption measured by the power consumption measuring unit 210 is used to determine whether there is a margin, and the control of the air conditioner 200 is performed using data prepared in advance.

  Note that the power consumption prediction unit 340 collects information from the device power consumption measurement unit 210, the environment measurement unit 260, and the device operation control unit 320, and corrects the power consumption prediction model as needed. That is, when the power consumption predicted by the power consumption prediction unit 340 and the actual power consumption of the air conditioner 200 measured by the device power consumption measurement unit 210 are different, the power consumption prediction unit 340 has predicted. The power consumption prediction model is corrected so that the power consumption becomes closer to the actual power consumption of the air conditioner 200. As described above, the power consumption of the air conditioner 200 measured by the device power consumption measurement unit 210 of the third embodiment is used to improve the accuracy of power consumption prediction performed by the power consumption prediction unit 340.

  If the manufacturer that manufactures the generator control system and the manufacturer that manufactures the air conditioner 200 are the same, detailed information on the power consumption of the air conditioner 200 is obtained in advance, and this information is used to obtain very accurate accuracy. It is possible to predict good power consumption. Therefore, when the manufacturer that manufactures the generator control system and the manufacturer that manufactures the air conditioner 200 are the same, it is not necessary to improve the prediction accuracy of the power consumption of the air conditioner 200 during operation of the air conditioner 200, and the generator control system Since it is possible to accurately predict power consumption immediately after the start of use, the generator control system of the second embodiment may be used.

  However, when the manufacturer that manufactures the generator control system is different from the manufacturer that manufactures the air conditioner 200, the manufacturer that manufactures the generator control system obtains detailed information on the power consumption of the air conditioner 200 in advance. It will be difficult to keep. In some cases, the generator control system may be installed later as an adapter. In such a case, it is also difficult to specify what type of air conditioner is of which manufacturer. Even in such a case, by using the generator control system of the third embodiment, it is possible to predict power consumption with a low accuracy immediately after the start of use of the generator control system. The more it is used, the more accurately the power consumption can be predicted, and the air conditioner 200 can be accurately controlled.

  Further, since the predicted value of the power consumption of the air conditioner 200 of the device power consumption prediction unit 340 is insufficient in accuracy, the power consumption of the air conditioner 200 whose setting state (setting parameter) is controlled by the device operation control unit 320 is Since the commercial power is supplied from the commercial power system 380, the air conditioner 200 can be operated normally.

  In addition, when the above control is performed, the air conditioner 200 is operated in a setting state (setting parameter) different from the setting state (setting parameter) actually set by the user, which may cause inconvenience for the user. .

  Therefore, for example, the power information display unit 390 is in energy-saving control (the state in which the above control is performed), the operation state of the device 200 by the control, the time transition of the measured value or predicted value of the power consumption of the device 200 The control information is presented to the user in an easy-to-understand manner through the interface screen, such as an estimate of power cost reduction through control.

  As a result, the user can set energy-saving operation of the device 200 according to the time zone and lifestyle, and even if inconvenience is felt, the current operation state of the device 200 is disclosed, so the user's A sense of incongruity with control can be reduced.

  As described above, according to the third embodiment, as in the second embodiment, the generator control that reduces the purchase of commercial power due to the rapid increase in power consumption of the device 200 and takes advantage of the cost merit of introducing the generator. A system can be provided.

  In addition, this embodiment is an essential configuration in a closed power supply system that does not assume the purchase of commercial power.

  The device power consumption prediction unit 340 collects information from the device power consumption measurement unit 210, the environment measurement unit 260, and the device operation control unit 320, and checks whether the measured power consumption is in accordance with the predicted power consumption. Since the power consumption prediction model is corrected at any time, the power consumption simulation of the device 200 can be performed with higher accuracy than in the second embodiment.

(Embodiment 4)
Next, a fourth embodiment will be described.

  The second embodiment is connected to the commercial power system 380, and when a power shortage occurs, the power consumption of the device 200 is predicted while receiving supply of the shortage of power from the commercial power system 380. Although the case where the power consumption of the device 200 exceeds the power generation of the generator 100 by controlling the setting state (setting parameter) of the device 200 using the prediction result has been described in Embodiment 4, the commercial power system A generator control system that is not connected to 380 and therefore does not receive commercial power from the commercial power system 380 will be described.

  FIG. 4 is a configuration diagram of the generator control system in the present embodiment.

  Unlike the generator control system of the second embodiment, the generator control system of the fourth embodiment is not connected to the commercial power system 380. Therefore, the generator control system of Embodiment 4 does not receive supply of commercial power from the commercial power system 380.

  Other than that, the generator control system of Embodiment 4 has the same configuration as the generator control system of Embodiment 2.

  Next, the operation of the present embodiment will be described focusing on the differences from the second embodiment.

  Similar to the second embodiment, the case where the device 200 is an inverter air conditioner (hereinafter referred to as the air conditioner 200) will be described.

  When the user turns on the air conditioner 200 while the generator 100 is operating at a constant power generation and the air conditioner 200 is stopped, the device operation detection unit 330 immediately detects this and sets the current setting of the air conditioner 200 in the power consumption prediction unit 340. Output status immediately.

  The power consumption prediction unit 340 predicts the power consumption when the air conditioner 200 is operated in the set state. Specifically, the outside temperature and the room temperature of the room in which the air conditioner 200 is installed are acquired from the environment measurement unit 260, and the difference between the set temperature and the outside air temperature, the difference between the set temperature and the room temperature, and the air volume are calculated. Prediction is performed using a regression line (or regression curve) as a variable, or a power consumption prediction model such as a neural network that receives room temperature, outside air temperature, set temperature, and air volume as inputs.

  That is, the power consumption predicting unit 340 holds a control algorithm for determining control parameters (such as fan rotation frequency) of the air conditioner and a power consumption table when operating with the determined control parameters, and the outside air temperature and the air conditioner are determined. Air conditioning control is simulated from the temperature data of the installed room, and instantaneous power consumption is predicted.

  As another method, there is a prediction method using an interpolation function such as a neural network. In other words, when the device is an air conditioner, the instantaneous instantaneous power consumption is predicted using a neural network that is trained to output power consumption when environmental conditions (outside temperature, room temperature) and set temperature are input in advance. To do.

  The generator control unit 310 outputs a control signal to the generator 100 so that the power consumption of the device 200 predicted by the power consumption prediction unit 340 is set as a power generation target of the generator 100. At that time, the device operation control unit 320 performs the following control.

  When the generator 100 starts to increase the generated power according to the control signal from the generator control unit 310, the device operation control unit 320 uses the generated power of the generator 100 obtained by the generated power measurement unit 110 to be consumed by the air conditioner 200. The device 200 is controlled so that the power does not exceed. For example, when the air conditioner 200 is turned on with the operation mode “cooling”, the set temperature “25 ° C.”, and the air volume “strong” and the set parameter is set, the device operation control unit 320 first sets the air conditioner 200 to the set temperature “27 ° C.”. ”, Make the air flow“ fine ”.

  During the time from when the air conditioner 200 is turned on and the operation of the air conditioner 200 is started until the power consumption of the air conditioner 200 exceeds the power generation of the generator 100, the device operation control unit 320 performs the above control. Therefore, there is no case where the total power consumption of the air conditioner 200 or the like exceeds the generated power of the generator 100 until the user turns on the air conditioner 200 and the device operation control unit 320 performs the above control.

  Therefore, the same control as that of the second embodiment can be performed without being connected to the commercial power system 380.

  In the fourth embodiment, when the air conditioner 200 is turned on, the device operation control unit 320 immediately sets the air conditioner 200 in a set state (setting) so that the power consumption of the air conditioner 200 does not exceed the power generation of the generator 100. However, the present invention is not limited to this. Even when the air conditioner 200 is turned ON, the operation of the air conditioner 200 is not actually started, and the device operation control unit 320 performs control so that the power consumption of the air conditioner 200 does not exceed the power generation of the generator 100. It is also possible to start actual operation of the air conditioner 200 for the first time after starting the operation. Even if it does in this way, the generator control system which does not need to receive supply of commercial power from the commercial power system 380 is realizable.

(Embodiment 5)
Next, a fifth embodiment will be described.

  The third embodiment is connected to the commercial power system 380. When a power shortage occurs, the power consumption of the device 200 is predicted while receiving the shortage of power supplied from the commercial power system 380, and The prediction state is used to control the setting state (setting parameter) of the device 200, and the prediction accuracy of the power consumption of the device 200 is improved using the measured value of the power consumption of the device 200. In the fifth embodiment, a generator control system that is not connected to the commercial power system 380 and therefore does not receive commercial power from the commercial power system 380 will be described.

  FIG. 5 is a configuration diagram of the generator control system in the present embodiment.

  Unlike the generator control system of the third embodiment, the generator control system of the fifth embodiment is not connected to the commercial power system 380. Therefore, the generator control system of the fifth embodiment does not receive the supply of commercial power from the commercial power system 380.

  Other than that, the generator control system of Embodiment 5 has the same configuration as the generator control system of Embodiment 3.

  Next, the operation of the present embodiment will be described focusing on the differences from the third and fourth embodiments.

  A case where the device 200 is an inverter air conditioner (hereinafter referred to as an air conditioner 200) will be described.

  When the user turns on the air conditioner 200 while the generator 100 is operating at a constant power generation and the air conditioner 200 is stopped, the device operation detection unit 330 immediately detects this and sets the current setting of the air conditioner 200 in the power consumption prediction unit 340. Output status immediately.

  The device power consumption prediction unit 340 predicts the power consumption of the air conditioner 200 as in the fourth embodiment. Then, the generator control unit 310 outputs a control signal to the generator 100 so that the power consumption of the device 200 predicted by the power consumption prediction unit 340 becomes the power generation target of the generator 100. Then, the device operation control unit 320 controls the device 200 as in the fourth embodiment.

  During the time from when the air conditioner 200 is turned on and the operation of the air conditioner 200 is started until the power consumption of the air conditioner 200 exceeds the power generation of the generator 100, the device operation control unit 320 performs the above control. Therefore, when the power consumption predicting unit 340 can predict the power consumption with high accuracy, the power consumption of the air conditioner 200 or the like until the user turns on the air conditioner 200 and the device operation control unit 320 performs the above control. Is not greater than the power generated by the generator 100.

  Therefore, the same control as that of the second embodiment can be performed without being connected to the commercial power system 380.

  In the fifth embodiment, when the air conditioner 200 is turned on, the device operation control unit 320 immediately sets the air conditioner 200 in a setting state (setting) so that the power consumption of the air conditioner 200 does not exceed the power generation of the generator 100. However, the present invention is not limited to this. Even when the air conditioner 200 is turned ON, the operation of the air conditioner 200 is not actually started, and the device operation control unit 320 performs control so that the power consumption of the air conditioner 200 does not exceed the power generation of the generator 100. It is also possible to start actual operation of the air conditioner 200 for the first time after starting the operation. Even if it does in this way, the generator control system which does not need to receive supply of commercial power from the commercial power system 380 is realizable.

  The power consumption prediction unit 340 collects information from the device power consumption measurement unit 210, the environment measurement unit 260, and the device operation control unit 320 in the same manner as in the third embodiment, and corrects the power consumption prediction model as needed. Do. That is, when the power consumption predicted by the power consumption prediction unit 340 and the actual power consumption of the air conditioner 200 measured by the device power consumption measurement unit 210 are different, the power consumption prediction unit 340 has predicted. The power consumption prediction model is corrected so that the power consumption becomes closer to the actual power consumption of the air conditioner 200.

  However, when the power consumption measured by the device power consumption measuring unit 210 of the air conditioner 200 matches the generated power of the generator 100, the generator 100 supplies enough power to meet the load of the air conditioner 200. There may be no state. Therefore, when the power consumption prediction unit 340 corrects the power consumption prediction model, the power consumption measured by the device power consumption measurement unit 210 of the air conditioner 200 matches the power generation of the generator 100. The power consumption measured by the device power consumption measuring unit 210 of the air conditioner 200 is not used. That is, the power consumption prediction unit 340 is a device power consumption measurement unit of the air conditioner 200 only when the power generated by the generator 100 is larger than the power consumption measured by the device power consumption measurement unit 210 of the air conditioner 200 by a predetermined value or more.
