Description

[Technical Field]

[0001] The present invention relates to a self-consignment management system for self-consigning self-generated electric power. [Background technology]

[0002] Patent Document 1 describes a self-consignment system. As an example of self-consignment, Patent Document 1 describes a power transmission service provided by a general electric utility that enables a company to supply electricity generated in-house at a factory or other facility to its own remote business premises using the power company's power transmission and distribution network. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-58141 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the system does not permit switching between self-dispatch and selling electricity, or simultaneously. For example, Article 2, Paragraph 1, Item 14 (c) of the Electricity Business Act specifies the scope of those who can use self-dispatch. Also, in some cases, a specific supply license must be obtained based on Article 17, Paragraph 1 of the Electricity Business Act.

[0005] On the other hand, as described in Patent Document 1, although the current social situation encourages the use of self-transportation in order to promote the use of renewable energy, if a large amount of surplus electricity is generated by self-generated solar power, the surplus electricity may remain even if self-transportation is used.

[0006] On the other hand, if this system is relaxed and solar power generation facilities installed for the purpose of selling electricity can be used for self-transportation, there will be a need to process that electricity economically.

[0007] Therefore, in order to solve the above-mentioned problems, an object of the present invention is to provide a self-consignment management system that can appropriately determine whether to self-consign or sell self-generated electricity. [Means for solving the problem]

[0008] The self-dispatch management system of the present invention comprises an acquisition unit that acquires source power generation data regarding the amount of electricity that can be generated at a self-power generation facility and external information that affects the amount of electricity that can be self-dispatched from the self-power generation facility, a prediction unit that predicts the amount of electricity consumed by the destination facility at which the self-dispatch is to be made, a prediction unit that predicts the amount of electricity that can be self-dispatched in the future from the source power generation data, and a decision unit that determines a self-dispatch execution process that indicates whether or not to carry out self-dispatch and selling of electricity based on the amount of electricity consumed by the destination facility and the amount of electricity that can be self-dispatched. [Effects of the Invention]

[0009] According to the present invention, it is possible to appropriately determine whether to self-consign or sell the electric power obtained by self-generation. [Brief explanation of the drawings]

[Figure 8] FIG. 10 is a diagram showing a self-wheeling and electricity selling plan in a modified example. [Figure 9] 1 is a diagram illustrating an example of a hardware configuration of an energy management system 100 according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0011] The present disclosure will be described with reference to the accompanying drawings. Whenever possible, the same parts are designated by the same reference numerals and redundant description will be omitted.

[0012] FIG. 1 is a diagram showing a system configuration including an energy management system 100 according to the present disclosure.

[0013] The energy management system 100 corresponds to a self-consignment management system, and is a server device that manages the power generated by the power facility 300 using photovoltaic power generation.

[0014] The electricity rate server 200 is a server that stores electricity rates, and stores the selling price, buying price, and self-wheeling fee of electricity.

[0015] The power facility 300 is a facility that generates electricity through solar power generation. The power facility 300 has a solar power generation function, a power transmission function, and a communication function. The communication function acquires the amount of electricity generated by the solar power generation function and transmits it to the energy management system 100. In the present disclosure, the power facility 300 is a base station for mobile phone communications scattered throughout various locations, and the base station operates using commercial power and solar power. In the present disclosure, surplus electricity generated by solar power generation can be self-consignment or sold via the power transmission and distribution facility 300b via the power transmission line L.

[0016] The predictive management server 400 is a server that stores information for predicting weather information and traffic information. Because the power facility 300 generates power through solar power generation, power generation is affected by weather information, including sunshine information. The energy management system 100 uses the weather information to predict the power generated by the power facility for the next day. Similarly, the predictive management server 400 may also manage traffic information for the base station, which is the power facility 300. This allows the energy management system 100 to predict future traffic information, such as for the next day, and predict its power consumption.

[0017] The transmission management server 500 is a server located in the related organization 500a, and has a management table 501. The related organization 500a is, for example, the Agency for Cross-regional Coordination of Transmission Operators. This organization has a supply and demand adjustment function. The transmission management server 500 receives a transmission plan from the energy management system 100, and performs billing processing for the electricity used at the self-transmission destination facility 300a based on the transmission plan.

[0018] Next, the configuration of the energy management system 100, which corresponds to a self-consignment management system, will be described. Fig. 2 is a block diagram showing the functional configuration of the energy management system 100. This energy management system 100 includes a power data receiving unit 101, a prediction data receiving unit 102, an electricity rate information receiving unit 103, a power information processing unit 104, a power amount prediction unit 105, a plan determination unit 106, and a plan transmission unit 107.

[0019] The power data receiving unit 101 is a part that receives power data indicating the power generated from the power facility 300.

[0020] The forecast data receiving unit 102 is a part that receives forecast data such as weather information and / or traffic information of base stations (communication devices installed in the power facility 300) from the forecast management server 400. The weather information and traffic information include information for the present and future (for example, the next day). Future information is, for example, information about the time of self-consignment or the time of selling power. In this disclosure, explanations are given assuming that a decision on whether to consign or sell power is made the next day, but this is not limited to this.

[0021] The electricity rate information receiving unit 103 is a part that receives electricity rate information from the electricity rate server 200 .

[0022] The power information processing unit 104 is a part that aggregates power data, forecast data, and electricity rate information.

[0023] The power amount prediction unit 105 uses power data, prediction data, and electricity rate information to predict the power generation and power consumption of the photovoltaic power generation at the power facility 300, as well as the power generation and power consumption at the self-consignment destination facility 300a. The prediction is performed using a known method. For example, the power consumption at the power facility 300 and the self-consignment destination facility 300a is calculated from past history (e.g., traffic volume), and may be calculated as the average value for the past week or the average value for the same day of the week for the past month. Similarly, the power generation amount may be calculated from past history, or may be calculated by taking into account the weather (hours of sunshine) predicted from a weather forecast, taking into account the photovoltaic power generation.

[0024] The plan determination unit 106 determines a plan for whether to self-consign or sell the electricity based on the power generation and power consumption at the power facility 300 (self-consignment source) and the self-consignment destination facility 300a. The plan includes a consignment schedule, a power generation source (facility ID), a self-consignment destination (facility ID), and the amount of electricity to be self-consign.

[0025] The plan transmitting unit 107 is a part that transmits a plan to the consignment management server 500 .

[0026] A description will be given of the operation of the energy management system 100 configured as above. FIG.

[0027] The forecast data receiving unit 102 receives forecast data correlated with power (S101). The power data receiving unit 101 receives power data of power generated in the power facility 300 (S102). The power rate information receiving unit 103 receives power rate data (S103). These reception processes may be performed simultaneously. Furthermore, the order is not limited to the above.

[0028] The power information processing unit 104 aggregates the power data, forecast data, and electricity rate data. Then, the power amount forecasting unit 105 predicts the power generation and power consumption (demand forecast) of the power facility 300 and the power generation and power consumption (demand forecast) of the self-consignment destination facility 300a based on the forecast data correlated with power and the power data of the power facility 300 (S104).

[0029] More specifically, the power amount prediction unit 105 predicts the amount of power W1 to be generated by solar power generation on the next day based on weather information (prediction data) for the power facility 300 on the next day. The power amount prediction unit 105 also predicts the amount of power consumption W2 at the power facility 300 on the next day based on traffic information for the power facility 300.

[0030] The power amount prediction unit 105 also predicts the amount of power generated W3 and the amount of power consumed W4 by solar power generation at the predetermined self-consignment facility 300a. These are the amount of power generated W3 and the amount of power consumed W4 for the next day, respectively. The power facility 300 and the self-consignment facility 300a are facilities that have the same equipment, and have solar power generation and communication functions.

[0031] Next, the plan determination unit 106 determines whether to perform self-consignment or power sale when the amount of power W1 generated by photovoltaic power generation is greater than the amount of power consumption W2 at the power facility 300. If the amount of power W1 is less than the amount of power consumption W2, neither self-consignment nor power sale can be performed, and therefore the process of selecting between self-consignment and power sale is not performed.

[0032] If the generated power amount W1 is greater than the consumed power amount W2, the plan determination unit 106 calculates the costs of self-consignment and power sale from the predicted generated power and consumed power in order to select self-consignment or power sale (S105). The costs here indicate the power purchase costs at the self-consignment destination facility 300a.

[0033] The plan determination unit 106 first calculates the amount of power that can be self-dispatched by calculating the amount of self-dispatched power W5 = the amount of generated power W1 - the amount of consumed power W2. Hereinafter, unless otherwise specified, the consumed power W4 > the amount of self-dispatched power W5, and all of the self-dispatched power is self-dispatched, resulting in the self-dispatched power W5. Note that there may be no consumed power W2 (no power consumption at the power facility 300), in which case the amount of generated power W1 may be used as the power that can be self-dispatched.

[0034] Then, the plan determination unit 106 calculates the purchasing cost of the self-consignment destination facility 300a at the time of self-consignment using the following formula. This formula is based on the purchasing cost of the shortage of electricity. Figure 4 is a diagram showing an outline of the calculation for self-consignment and electricity sale.

[0035] Cost A for self-consignment = (power consumption at the self-consignment destination when self-consignment is not performed (power consumption W4) - power amount self-consignment (self-consignment power amount W5) * electricity price at the time of purchase + self-consignment cost ... (1) The self-transmission fee corresponds to the amount of transmission line usage when self-transmission is performed. Generally, the transmission fee is set per unit of power, but it may also be set as a fixed amount. In the above, it is set as a fixed amount for the sake of convenience, but it may also be a fee according to the cost of self-transmission.

[0036] Furthermore, the plan determination unit 106 calculates the purchase cost of the self-consignment destination facility 300a at the time of selling the electricity by the following calculation formula.

[0037] Sales profit B1 = Amount of electricity sold (Amount of generated electricity W1) * Unit price of electricity at the time of sale ... (2) Cost B2 = Power consumption of the destination (power consumption W4) * Unit price at time of purchase ... (3) Purchase cost of self-consignment destination B=B2-B1 …(4) The sold power may be calculated as generated power W1 minus consumed power W2.

[0038] Then, the plan determination unit 106 determines whether to perform self-consignment or sell the electricity based on the purchase cost A for self-consignment at the self-consignment destination facility 300a and the purchase cost B for selling the electricity, and formulates a plan (S108). Note that here, B2>B1.

[0039] For example, if purchase cost A > purchase cost B, the plan determination unit 106 formulates a plan to sell electricity. Also, if purchase cost A < purchase cost B, the plan determination unit 106 formulates a plan to carry out self-consignment. Note that if purchase cost A = purchase cost B, whether to carry out self-consignment or sell electricity may be set in advance or may be determined based on other factors.

[0040] In the present disclosure, as shown in FIG. 5, the plan determination unit 106 determines, for each power generation source (facility ID) that is a power facility 300, the date of self-dispatch or power sale, the plan (self-dispatch or power sale), and if it is self-dispatch, the self-dispatch destination and the amount of power to be self-dispatch or power sale as a plan.

[0041] Figure 5(a) shows the plan contents when self-dispatch is performed, and Figure 5(b) shows the plan contents when selling electricity. When selling electricity, there is no description of the self-dispatch destination. According to these figures, the plan includes the generator that supplies the electricity, the date (scheduled date) of self-dispatch / electricity sale, a plan indicating whether self-dispatch or electricity sale will be performed, the dispatch destination in the case of self-dispatch, and the amount of electricity to be dispatched or sold.

[0042] Next, the operation of the consignment management server 500 will be described. Fig. 6 is a flowchart showing the operation of the consignment management server 500. In the consignment management server 500, its plan receiving unit (not shown) receives a plan from the energy management system 100 (S201). Then, its control unit (not shown) registers the plan in the management table 501 (S202). That is, the control unit acquires the amount of power consumption (predicted value) at its own consignment destination, and registers the information of Fig. 7(a) in the management table 501. The amount of power consumption (predicted value) at its own consignment destination may be predicted by the consignment management server 500 as described above, or may be acquired from the energy management system 100.

[0043] The plan receiving unit then receives the plan contents shown in Fig. 5 and extracts a data string (Fig. 7(a)) in which the ID (e.g., 1001 in Fig. 5) indicated by the self-consignment destination is the billing target. The control unit then registers the amount of electricity to be consigned and sold indicated in the plan contents obtained in Fig. 5 as the amount of electricity to be consigned (Fig. 7(b)).

[0044] The control unit then calculates the amount of power to be billed by subtracting the amount of power to be wheeled from the amount of power to be used. The control unit performs billing processing using the calculated amount of power to be billed (S203). The billing processing is performed by the wheeling management server 500 to the electric power company. Specifically, this billing data is sent to the electric power company's server. The electric power company performs billing processing based on the amount of power for wheeling and selling, respectively, for self-wheeling and selling, which are specified in the plan type.

[0045] In the case of self-consignment, billing is performed taking into account the self-consignment fee. For example, when processing a bill for a company with self-consignment destination 1001 and power generation source 0001, the amount of power consignment and power sale is subtracted from the power used at the self-consignment destination, and the self-consignment fee is also added to process the bill. In the case of power sale, when processing a bill for the company with power generation source 0001, the amount of power sold is multiplied by the selling price of the power (so-called negative billing).

[0046] In the present disclosure, the power generation source and the self-consignment destination are the same corporation or company, and therefore the profit of the self-consignment destination can be considered to be the same as the profit of the power generation source.

[0047] In the above explanation, it is assumed that the power consumption W4 of the self-consignment destination is greater than the self-consignment capacity W5 (self-consignable power), but there are also cases where the power consumption W4 is less than the self-consignment capacity W5. Here, we will explain such cases. In process S106 in FIG. 3, the plan was formulated to determine whether to perform self-consignment or sell the power, but this is not limited to this. For example, if the power consumption W4 is less than the self-consignment capacity W5, the power facility 300 may self-consign to the self-consignment destination facility 300a and sell the surplus power. In this case, by comparing the cost of self-consignment with the cost of selling the power, if it is determined that selling the power is more cost-effective, the power facility 300 may sell the power without performing self-consignment.

[0048] For example, the plan determination unit 106 calculates the energy shortage W6 at the self-consignment destination facility 300a by calculating the energy shortage W6 at the self-consignment destination facility 300a as follows: (energy generation amount W3 - energy consumption amount W4) In the above example, it is assumed that the energy consumption amount W4 is greater than the energy generation amount W3 and is therefore insufficient.

[0049] Then, the power amount prediction unit 105 in the energy management system 100 calculates the amount of power sold W7 = the amount of self-consignment power W5 (self-consignable power) + the amount of power shortage W6. Note that, based on the above assumptions, the sign of W6 is negative. In other words, when the power shortage at the self-consignment destination is made up for with the power that can be self-consignment, the surplus power becomes the amount of power sold W7.

[0050] The plan determination unit 106 formulates plans for both self-dispatch and power sale. FIG. 8 is a diagram showing the specific plan contents. In the diagram, two data strings for power generation source (facility ID): 0001 are created, and these are the plans for self-dispatch and power sale, respectively. The plan transmission unit 107 transmits these to the wheeling management server 500.

[0051] The consignment management server 500 performs the billing process as described above.

[0052] The plan determination unit 106 may determine whether to sell the surplus power after self-consignment or to sell all the power without self-consignment, based on the power purchasing cost at the self-consignment destination facility 300a. In the present disclosure, when cost A > cost B, the plan determination unit 106 determines to sell all the power without self-consignment.

[0053] Next, the effects of the self-consignment management system of the present disclosure will be described. In the energy management system 100, which is the self-consignment management system of the present disclosure, the power data receiving unit 101 receives source power generation data (power data of the power facility 300) relating to the amount of power that can be generated at the power facility 300, which is a self-power generating facility. In addition, the prediction data receiving unit 102 receives external information (e.g., weather or traffic information) that affects the amount of power self-consignment from the power facility 300 from the prediction management server 400.

[0054] The power information processing unit 104 then aggregates these data, and the power amount prediction unit 105 predicts the power consumption (destination power consumption) at the self-consignment destination facility 300a. For example, the power consumption of the self-consignment destination facility 300a for the next day is predicted. Note that the self-consignment destination facility 300a may also generate its own power, and in this case, the power consumption (destination power consumption) of the self-consignment destination facility 300a indicates the amount of power that is insufficient.

[0055] The power amount prediction unit 105 also predicts the amount of power that can be self-consignment based on the power generation data (supply source power data) of the power facility 300 that is the power supply source. For example, it predicts the amount of power that can be self-consignment on the next day.

[0056] The plan determination unit 106 determines the self-consignment execution process, which indicates whether to implement self-consignment or power sale, based on the power consumption of the supply destination and the amount of power that can be self-consigned. In the above embodiment, the decision on whether to self-consign or power sale is based on the purchase cost of the self-consignment destination, but this does not necessarily have to be included. For example, prediction data and the like may be taken into consideration, and if there is self-consignable power, self-consignment may be performed, and if there is not, self-consignment may not be performed. Furthermore, if there is surplus power left over after self-consignment, it may be decided to sell it.

[0057] In the present disclosure, the self-consignment execution process includes performing at least one of self-consignment and electricity selling, or not performing either.

[0058] This configuration makes it possible to appropriately determine whether to self-consign or sell the electricity obtained by self-generated power such as solar power generation, and thus to use the electricity without waste.

[0059] For example, suppose there are two geographically separated power facilities 300 and a self-consignment facility 300a, and the solar power generation system installed at one of the power facilities 300 generates a large amount of surplus power that cannot be consumed by both facilities. In this case, even if the surplus power is consigned by self-consignment, the surplus power that cannot be used cannot be sold and is wasted. In the present disclosure, by predicting the power generation and power consumption, it is possible to determine whether to consign or sell the power, and the power obtained by self-generation can be used without waste.

[0060] In the present disclosure, it has been described that the power facility 300 uses the self-generated power for itself, but it is not necessarily required to use it for itself.

[0061] Also, as will be described later, although it depends on the usage fee for self-consignment, there is a high possibility that selling electricity will be more cost-effective. In such a case, selling electricity will be selected. Conversely, if self-consignment can reduce costs, self-consignment will be selected.

[0062] That is, the energy management system 100 of the present disclosure may have an electricity rate information receiving unit 103 as an acquisition unit, and may acquire electricity rate information for self-consignment, electricity selling, and electricity purchase. The plan determination unit 106 further uses the electricity rate information to calculate the profit for self-consignment and the profit for electricity selling, and determines the self-consignment execution process based on the calculated profit.

[0063] The above profit may be interpreted as cost, which in the present disclosure corresponds to the cost of purchasing electricity at the self-consignment destination facility 300a.

[0064] The profit from the self-consignment is calculated based on the cost of purchasing the power that is the shortfall obtained by subtracting the self-consignment power amount W5 from the power shortage W6 based on the power consumption amount W4 at the self-consignment destination facility 300a. The plan determination unit 106 compares the purchase cost with the profit obtained from selling the power to determine the self-consignment execution process.

[0065] In this disclosure, the profit obtained by selling electricity refers to the cost at the self-consignment facility 300a. That is, it is the amount obtained by subtracting the sales profit (the above-mentioned sales profit B1) from the purchase cost of purchasing the shortage of electricity at the self-consignment facility 300a.

[0066] The plan determination unit 106 determines to perform self-consignment when the profit from self-consignment is greater than the profit from selling the power, and to sell the power when the profit from selling the power is greater than the profit from self-consignment.

[0067] That is, in this disclosure, profit is synonymous with the purchase cost at the self-consignment facility 300a. The profit when self-consignment is based on the purchase cost of the power shortage at the self-consignment facility 300a at that time, and the profit when selling electricity is based on the amount obtained by subtracting the sales profit from the purchase cost of the power shortage at the self-consignment facility 300a.

[0068] This configuration makes it possible to formulate a plan that can comprehensively reduce electricity costs based on the profits from self-consignment and the profits from selling electricity.

[0069] The plan determination unit 106 in the energy management system 100 of the present disclosure determines to sell surplus power obtained by subtracting the power consumed by the power facility 300 and the power self-consignment from the self-generated power.

[0070] This configuration allows surplus power to be used without waste, which is effective in terms of power costs.

[0071] The plan determination unit 106 determines to sell the electricity without self-consignment when the profit from selling the electricity is greater than the profit from self-consignment.

[0072] According to this configuration, if selling the electricity is more advantageous in terms of electricity costs, that is, if selling the electricity will result in more profit, it is better to sell the electricity without self-consignment.

[0073] In the energy management system 100 according to the present disclosure, the plan determination unit 106 generates a plan indicating whether or not to implement at least one of the determined self-dispatch and power sale. Then, the plan transmission unit 107 transmits the plan to the dispatch management server 500, which is a management server that manages self-dispatch and power sale.

[0074] The wheeling management server 500 performs billing processing for the power used by the users (corporations, etc.) of the power facility 300 in cooperation with a server that handles billing processing at the power company.

[0075] The external information used by the energy management system 100 of the present disclosure is predicted information on the power consumption at the power facility 300 (self-power generation facility) when self-consignment or power sales are performed. For example, since the power consumption varies depending on the traffic of the base station, the power consumption is predicted based on the traffic prediction.

[0076] The power facility 300 also has a function of generating solar power. By using the weather at the installation location of the power facility 300 as external information, it is possible to predict the power generation capacity of the power facility 300.

[0077] The energy management system 100, which is the self-consignment management system of the present disclosure, can be expressed as follows.
