  Here, assuming a market where energy is virtually exchanged, there is a possibility that a plurality of participants may acquire ownership in duplicate for a block of energy produced. For example, when energy is exchanged between N storage batteries, since “consumption-reception” can be exchanged, it is conceivable that ownership will be N times the stored energy.

  This can result in duplication of ownership if only one of energy storage and consumption is observed. That is, in the prior art, it has not been guaranteed that the produced energy can be reliably produced and can be consumed.

  The present invention has been made in view of the above circumstances, and provides an energy management apparatus, system, and program capable of registering, with respect to a user, exchangeable amounts according to the results of energy production or consumption. The purpose is to

  In order to achieve the above object, in the energy management device according to the present invention, the amount of energy produced by the energy production device of the user and the energy consumption device of the user consuming the energy produced by the energy production device are consumed A calculation unit that receives the consumed amount of energy as an input and calculates the replaceable amount of energy produced by the energy production device based on the smaller one of the consumed amount and the produced amount; and the calculated user And a management unit that registers the exchangeable amount in a ledger and notifies the user of addition and subtraction of the exchangeable amount in the ledger.

  Further, a program according to the present invention includes a computer, a production amount of energy produced by a user's energy production apparatus, and an energy consumption consumed by the user's energy consumption apparatus that consumes the energy produced by the energy production apparatus. A calculation unit for receiving as an input, and calculating a replaceable amount of energy produced by the energy production apparatus based on the smaller one of consumption and production, and the calculated replaceable amount of the user It is a program for making it function as a management part which registers in a ledger and notifies the addition and subtraction of the exchangeable amount in the ledger to the user.

  According to the energy management device, system, and program of the present invention, the exchangeable amount of energy produced by the energy production device is calculated based on the smaller one of consumption amount and production amount, and the calculated user exchange By registering the possible amount in the ledger and notifying the user of addition / subtraction of the exchangeable amount in the ledger, it is possible to register the user with the replaceable amount according to the actual result of energy production or consumption.

<Configuration of Energy Management System According to Embodiment of the Present Invention>

  Next, the configuration of the energy management system according to the embodiment of the present invention will be described. As shown in FIG. 1, the energy management system 10 according to the embodiment of the present invention includes a user terminal 4, an energy production device 5, an energy consumption device 6, an observation device 7, and an ownership exchange market 8, The energy exchange market 9 and the energy management device 20 are configured and connected via the network 3.

  The user terminal 4 is a terminal that receives, from the energy management apparatus 20, a notification of the updated content regarding the user.

  The energy production device 5 is a plurality of energy production devices that each user owns and produces energy such as electric power.

  The energy consuming device 6 is a plurality of energy consuming devices that each user owns and consumes the energy produced by the energy producing device 5. Moreover, the energy consumption apparatus 6 shall be connected in a different area, and shall consume the energy which the energy production apparatus 5 of the area produced.

  The observation device 7 is provided for each of the energy production devices 5, and observes the amount of energy production of the energy production device 5 and the amount of energy consumption of the energy consumption device 6, and transmits it to the energy management device 20 as observation data. Multiple observation devices. In addition, the corresponding user name and the identification number of the energy producing device 5 are sent to the energy management device 20 together with the amount of energy production and the amount of energy consumption to be sent. The identification number corresponds to the energy production device 5, the user name of the user who owns the energy production device 5, and the user terminal 4.

  The ownership exchange market 8 is a market for exchanging energy ownership. In the ownership exchange market 8, the energy ownership at the time of first setting the exchangeable amount is the same as the user who is the owner of the energy producing apparatus 5, but the energy ownership in the ownership exchange market 8 Can be exchanged. In the property exchange market 8, it is possible to purchase goods such as goods, money, and services based on the property right. Ownership is transferred to the payee when the goods are purchased.

  The energy exchange market 9 is a market for exchanging exchangeable amounts of energy. The exchangeable amount shall be exchangeable only between exchangeable amounts. This assumes, for example, a mechanism that simulates a bank-to-bank transaction account in a bank.

  Details of exchanges in the ownership exchange market 8 and the energy exchange market 9 will be described later.

  The energy management device 20 is configured to include a communication unit 22, a calculation unit 30, a management unit 32, and a ledger 34.

  The calculation unit 30 receives as input the amount of energy produced by the energy production device 5 of each user and the amount of energy consumed by the energy consuming device 6 of each user, and the smaller one of the consumption amount and the production amount The exchangeable amount of energy produced by the energy production device 5 is calculated based on

  The exchangeable amount is calculated by the following equation (1).

... (1)

  p is the production amount and q is the consumption amount. Thus, the exchangeable amount is calculated by weighting the weight α of the credit of the energy producing device 5 to the smaller one of the consumption amount and the production amount. The credit α is close to 1 when the credit is high. For example, when the data (production amount, consumption amount) obtained from the device varies greatly depending on the time or day, or the device or the owner can not prepare energy for the replaceable amount due to a failure of the device (discarded) If it is in the past, make α smaller than 1, etc. If the system is not concerned with the credit level, it may be α = 1. Specific examples will be described later.

  The management unit 32 registers information such as the owned amount and the owner of the owner in the ledger 34 together with the user exchangeable amount calculated by the calculation unit 30. Further, the management unit 32 notifies the user terminal 4 of the user who owns the energy production apparatus 5 of the exchangeable amount in the ledger 34, the registration of the owned amount, the addition / subtraction, and the change history of the ownership. The information in the ledger 34 is updated by exchanging the exchangeable amount or ownership by the ownership exchange market 8 or the energy exchange market 9.

  An example of the information registered in the ledger 34 is shown in FIG. As shown in FIG. 2, in the ledger 34, the identification number of the energy production device 5, the production amount, the consumption amount, the replaceable amount, the registered user, the owned amount, and the information of the owner are registered.

  Here, an example in which the information in the ledger 34 is updated will be described.

  With reference to FIG. 3, the exchangeable amount, the flow when ownership is exchanged in the energy exchange market 9, and the update contents of the ledger 34 will be described.

  In FIG. 3, for example, the user A (ownership X) who is the energy owner of the identification number {xxxxxx} of the energy producing device 5 is energy in a different area geographically separated from the energy producing device 5 owned by the user A. It is assumed that the consumer 6 is connected to consume energy. In this case, only energy of X / β can be used. β is the exchange rate. The exchange rate β is determined by local power generation and transmission system bottlenecks. Thus, the exchange rate β has a role as, for example, equivalent to the exchange rate in the financial market. As a way of determining the exchange rate β, it is assumed that consumption can not exceed the total exchangeable amount of the area no matter how much exchangeable amount is in other areas. Further, in the energy management system 10, it is assumed that power can not be transmitted beyond the power transmission limit.

  At this time, as shown in FIG. 3, the contents of the ledger 34 are registered as the exchangeable amount X, the registered user A, the owner A, and the owned amount X for the identification number {xxxxxx} of the energy producing device 5. Further, for the identification number {yyyyyy}, it is assumed that the exchangeable amount Y is the registered user B. The user B is a user at the exchange destination having the energy producing apparatus 5 in different areas.

  Next, it is assumed that the user A consumes power by W (≦ X / β).

  At this time, in the energy exchange market 9, the exchangeable amount of W (≦ X / β) according to the exchange rate β between the regions, the energy production device 5 of the area where the user A exists (identification number {yyyyyy}, exchangeable amount) : Y, registered user: B) traded.

  The energy management apparatus 20 receives the contents of the trade from the energy exchange market 9 through the communication unit 22 and updates the ledger 34. The contents of the update are updated so that the exchangeable amount is subtracted from the exchangeable amount of the registered user A and the X- (W * β) and the exchangeable amount of the registered user A for the registered user A with the identification number {xxxxxx} as shown in FIG. . Also, for the registered user B, the exchangeable amount is updated to W * β. Further, the ownership amount of the owner A becomes X- (W * β), and the ownership amount W * β of the owner B is updated. On the other hand, for the registered user B with the identification number {yyyyyy}, the exchangeable amount is updated to YW. Also, the ownership amount of the owner B is updated to Y-W.

  Thus, the user B holds exchangeable amounts in two places. In the energy management system 10, the exchangeable amount of B may or may not be integrated as the identification number of the energy production device 5 in one place, so which method is selected is a contract with the user It can be set arbitrarily. In the case of integration, the inability to transmit power beyond the transmission limit affects the determination of the value of the exchange rate β (> 0). In the present system configuration, β = 1 may be used.

  Next, with reference to FIG. 4, the flow in the case where trading of goods, services, etc. by ownership is performed in the ownership exchange market 8 and the updated contents of the ledger 34 will be described.

  In FIG. 4, for example, it is assumed that the user C exhibits the product S in the ownership exchange market 8. At this time, the contents of the ledger 34 are registered as the exchangeable amount X, the registered user A, the owner A, and the owned amount X with respect to the identification number {xxxxxx} of the energy producing apparatus 5.

  Next, it is assumed that the owner A (ownership amount X) of the energy of the identification number {xxxxxx} trades the product C from the user C with the energy amount Z in the ownership exchange market 8.

  The energy management apparatus 20 receives the contents of the trade from the ownership exchange market 8 by the communication unit 22 and updates the ledger 34. As for the update content, as shown in FIG. 4, the exchangeable amount of the registered user A remains X for the identification number {xxxxxx}. In addition, the ownership amount of the owner A is updated to X-Z. In addition, the ownership amount Z of the owner C and the owner C is added. In addition, user A (ownership X) who is the owner of the energy production device 5 of the identification number {xxxxxx} submits energy Z to the ownership exchange market 8, and user C updates the ledger 34 as described above. The same operation is performed in the case where the energy Z is purchased from the user A by the product S.

  Next, with reference to FIG. 5, the flow when the consumption of the owner is observed and the update contents of the ledger 34 will be described.

  In FIG. 5, for example, it is assumed that the user C consumes the energy Q by the energy consuming device 6. At this time, the contents of the ledger 34 are: identification number {xxxxxx}, exchangeable amount of registered user A is X, production amount of the previous period is p, consumption amount of the previous period is q, production amount of this period, and consumption amount of this period Is blank. Further, for the owner A, it is assumed that the owned amount is XZ, and the owned person C and the owned amount Z of the owner C are. For convenience of explanation, it is assumed that an identifiable ID or the like is actually assigned to what is expressed as the previous term or the present term.

  Next, it is observed that user C consumed energy Q by the energy consumption device 6 by the observation device 7, and the energy production device 5 produced the consumption amount Q, the user name C, and the energy consumed by the energy consumption device 6 Identification number (here, {xxxxxx}) is transmitted to the energy management apparatus 20 as observation data.

  The energy management device 20 receives observation data from the observation device 7 through the communication unit 22 and updates the ledger 34. As for the update contents, as shown in FIG. 5, the exchangeable amount of the registered user A is updated to XQ for the identification number {xxxxxx}. In addition, Q is added as the consumption for this term, and the ownership of the owner C is updated to Z-Q.

  Next, with reference to FIG. 6, the flow when energy production is observed and the updated contents of the ledger 34 will be described.

  In FIG. 6, for example, it is assumed that the energy production device 5 generates the energy P. At this time, the contents of the ledger 34 are: identification number {xxxxxx}, exchangeable amount of registered user A is XQ, production amount of the previous period is p, consumption amount of the previous period is q, production amount of this period is blank, this period Consumption amount of Q is assumed. In addition, with respect to the owner A, it is assumed that the owned amount is XZ and the owned person C and the owned amount C of the owner C are the owned amount Z-Q.

  Next, it is observed that the energy production device 5 has generated the energy P by the energy production device 5 by the observation device 7, and the production amount P, the user name A, and the identification number {xxxxxx} are transmitted to the energy management device Ru.

  The energy management device 20 receives observation data from the observation device 7 through the communication unit 22 and updates the ledger 34. As for the contents of update, as shown in FIG. 6, the current production amount P is added to the identification number {xxxxxx}.

  Next, the energy management apparatus 20 calculates the replaceable amount X ′ in the calculation unit 30 based on the current production amount and the current consumption amount. Then, the ledger 34 is updated so as to add the calculated exchangeable amount X 'to the replaceable amount of the corresponding identification number registered in the ledger 34. As shown in FIG. 6, the replaceable amount of the registered user A is updated to X−Q + X ′ with respect to the identification number {xxxxxx} as shown in FIG. 6. Also, the ownership amount of the owner A is updated as X−Z + X ′.

  The consumption update shown in FIG. 5 and the production update shown in FIG. 6 progress continuously in random order in time series, and in the energy management apparatus 20, the consumption in this term and the production in this term are updated. If it is, calculate the exchangeable amount.

  Further, the case where the weight α is updated in the calculation unit 30 will be described.

  For example, when a certain user consumes energy by the energy consuming device 6, the energy produced by the energy producing device 5 becomes empty, and the observation device 7 transmits an empty state signal to the energy management device 20. The calculation unit 30 of the energy management device 20 updates the weight α when the empty state signal is received. The weight α is updated, for example, by the following update equation (2).

... (2)

  γ is a coefficient whose value decreases when an empty state occurs. Further, the update equation of the weight α may be α ′ = (exp (α) −1) / (e−1) or the like. Alternatively, the weights may be updated periodically if no idle signal is sent. If the idle state signal is not transmitted, α may be updated to, for example, α ′ = log ((e−1) * α + 1) so as to be close to 1.

  The calculation unit 30 of the energy management device 20 calculates the replaceable amount by the above equation (1) using the updated weight α. Then, the management unit 32 applies the replaceable amount calculated by updating the weight α instead of adding the replaceable amount in the ledger 34 on the condition that the empty state signal is received. Update as exchangeable amount of identification number.

  In addition, when the management unit 32 receives an empty state signal, the possession amount of the user terminal 4 of the owner of the energy production device 5 is negative according to the updated contents of the ledger 34, the energy production device The communication unit 22 notifies the user terminal 4 that 5 is broken.

<Operation of the energy management system according to the embodiment of the present invention>

  Next, the operation of the energy management apparatus 20 in the energy management system 10 according to the embodiment of the present invention will be described. The energy management device 20 executes an energy management device 20 processing routine shown in FIG.

  First, in step S100, it is determined whether or not observation data has been received from the observation device 7. If it has been received, the process proceeds to step S102, and if it has not been received, the process proceeds to step S112. As observation data, at least one of the energy production amount of the energy production device 5 and the energy consumption amount of the energy consuming device 6 is received.

  Next, in step S102, it is determined whether or not an empty state signal has been received from the observation device 7. If it has been received, the process proceeds to step S104, and if it has not been received, the process proceeds to step S106.

  In step S104, the calculation unit 30 calculates the weight α and updates the weight according to the equation (2).

  In step S106, the observation data and the ledger 34 are referenced to determine whether there is a production amount and a consumption amount for the current period, and if there is, the process proceeds to step S108, and if not, the process proceeds to step S110. Do.

  In step S108, the calculation unit 30 receives as input the amount of energy produced by the energy producing device 5 of the user and the amount of energy consumed by the energy consuming device 6 of each user, according to the above equation (1). The exchangeable amount of the energy produced by the energy producing device 5 is calculated based on the smaller one of the consumption amount and the production amount.

  In step S110, the management unit 32 updates the ledger 34 based on the received observation data or the observation data and the exchangeable amount calculated in step S108, and proceeds to step S116.

  In step S112, it is determined whether or not the content of the trade has been received from at least one of the ownership exchange market 8 and the energy exchange market 9. If it has been received, the process proceeds to step S114. If it has not been received, the process proceeds to step S100. Return to and repeat the energy management process routine.

  In step S114, the management unit 32 updates the ledger 34 based on the contents of the trade accepted in step S112, and proceeds to step S116.

  In step S116, the communication unit 22 notifies the user terminal 4 of the updated contents of the ledger 34, returns to step S100, and repeats the energy management processing routine.

  As explained above, according to the energy management device 20 according to the embodiment of the present invention, the exchangeable amount of energy produced by the energy production device 5 is calculated based on whichever of consumption and production amount is smaller. The registered exchangeable amount of the user is registered in the ledger 34, and the user is notified of addition / subtraction of the exchangeable amount in the ledger to notify the user of the exchangeable amount according to the actual result of energy production or consumption. Can be registered.

  Further, while the existing financial market regards stock as credit, the energy management system 10 according to the embodiment of the present invention treats the flow results as credit. Therefore, there is a merit that an infinite chain which stock produces stock does not occur. This realizes an economic system that can always be defined by the upper limit of the flow (energy production and consumption). Since the exchangeable amount is set only by producing and consuming energy, it is considered that the economic system can suppress infinite expansion.

  In addition, there is an advantage that loans by so-called show money in the financial market do not occur. This is because one storage battery (energy production device) can not be recycled to secure only the ownership. In addition, because energy is secured by collateral, there is an advantage that so-called attachment in financial markets does not occur. Moreover, if energy intervenes as collateral in this way, it can be assumed that even if the stock market collapses, the impact on energy flow will be small.

  Further, by introducing the exchangeable amount mechanism as in the embodiment of the present invention, energy can be treated as a substantial currency, and improvement of energy production efficiency can be expected. In addition, it is expected that efforts will be made to improve the performance of energy production devices and energy storage devices in order to prevent energy loss in some accidents by treating energy with currency.

  The present invention is not limited to the above-described embodiment, and various modifications and applications can be made without departing from the scope of the present invention.

  For example, in energy management system 10 of an embodiment mentioned above, although a case where observation device 7 was provided for every energy production device 5 was explained to an example, it is not limited to this. For example, in one observation device, a plurality of energy production devices (for example, energy production devices in a range that can be grouped by area) are associated, and energy production and consumption of the associated energy production devices are collectively observed You may do so.

  Further, for example, in the energy management system 10 according to the above-described embodiment, the case where the ownership exchange market 8 and the energy exchange market 9 are both included in the configuration has been described as an example, but Absent. For example, in the energy management system, only one of the ownership exchange market and the energy exchange market may be included, and only one of the markets may be traded.

  Further, for example, in the calculation unit 30 of the above-described embodiment, the exchangeable amount is calculated using the credit degree weight α as an example, but the present invention is not limited to this. For example, the replaceable amount may be calculated based on the smaller one of the consumption amount and the production amount without using the weight.
