  By the way, in solar power generation at home, solar power generation equipment is often installed on the roof of a detached house owned by a consumer, and in many cases, solar power generation equipment cannot be installed in a condominium or rental housing. In other words, consumers who live in condominiums and rental houses often cannot perform solar power generation even if they want to generate solar power. In addition, even when installing solar power generation equipment on the roof of a detached house, considering the various conditions related to power generation, such as the direction and area of the roof and the influence of shadows from surrounding buildings, it was worth the capital investment. When a sufficient amount of power is obtained, it is necessary to determine the installation of solar power generation facilities. For this reason, the capacity of the solar power generation equipment that can be installed is limited because the roof is narrow, or the roof is not facing south or there are many shades, so you must give up the installation of the solar power generation equipment Occurs. Furthermore, if it is necessary to renovate or renovate a detached house in the near future, the current installation of solar power generation facilities may be abandoned.

  In addition, there is a risk of rain leaks and roof damage due to the photovoltaic power generation equipment installed on the roof, and it is difficult to maintain and manage the photovoltaic power generation equipment. May give up. In addition, watt-hour meters for selling electricity need to be regularly replaced at the customer's expense and responsibility based on the Measurement Law, but such regular replacement work is a heavy burden for general consumers. It has become. In addition, there are cases where it is not known how to replace, or there is a case where it is not recognized that periodic replacement is necessary. As described above, there are cases where it is difficult to install and promote the photovoltaic power generation facility due to an impediment related to the operation of the photovoltaic power generation facility.

  Furthermore, when solar power generation equipment is installed in each home, the amount of power generation may be suppressed due to an increase in power system voltage, and the countermeasure work is generally borne by the consumer who is the installer of the solar power generation equipment. Must. In addition, surplus power generated by solar power generation at home and subtracting power consumed at home is purchased by the power company, including environmental value, but the environmental value of power consumed at home has been properly evaluated. Absent. In other words, even if solar power is generated and consumed at home, the contribution to the environment is hardly evaluated. On the other hand, there is a risk that the power quality may deteriorate due to the decentralized installation of solar power generation facilities in many homes. In such a case, it is assumed that the power company, etc. must carry out countermeasure work. . As described above, there are cases where it is difficult to install and promote the solar power generation equipment due to the obstructive factors accompanying the spread of the solar power generation equipment.

Accordingly, an object of the present invention is to provide a solar power generation facility distribution system capable of promoting the use of solar power generation by each household.

According to the present invention, power is supplied to the customers from transmission and distribution equipment, power generated by the photovoltaic power generation facilities is supplied to the power transmission and distribution equipment. Then, the power generation amount of each customer is calculated by the power amount calculation means based on the amount of power supplied from the solar power generation facility to the power transmission and distribution facility and the sales amount of each customer. That is, the amount of power generated by each customer's solar power generation is calculated, and the surplus power amount of each customer is calculated based on the amount of power generated by the customer and the amount of power consumed by each customer's house measured by the weighing means. Calculated. That is, when the amount of power generated by solar power generation exceeds the amount of power consumed at each customer's house, the amount of power that can be sold to an electric power company or the like is calculated.

  The invention of claim 2 is the solar power generation facility distribution system according to claim 1, wherein the consumer power generation amount is based on the consumer power generation amount and the power amount measured by the measuring means. A self-power consumption amount that is the amount of power consumed at a customer's house is calculated for each consumer, and the ratio of the self-power consumption amount of each consumer to all the self-power consumption amounts of all the consumers is calculated. Self-consumption calculating means for calculating the self-consumption ratio shown is provided.

  According to the present invention, among the amount of power generation considered as solar power generation by each consumer, the amount of power consumed at the customer's home, that is, the amount of power consumed by the home and consumed by the home is self-consumed power amount. Is calculated as Then, the ratio of the self-consumption power amount of each consumer to the self-consumption power amount of all consumers, that is, the total self-consumption power amount by the solar power generation facility, is calculated as the self-consumption ratio.

  The invention according to claim 3 is the solar power generation facility distribution system according to claim 1 or 2, based on the cost required for management and operation of the solar power generation facility and the amount of distribution stored in the distribution amount storage means.

It has the registration means registered in a means, It is characterized by the above-mentioned.

According to the first aspect of the present invention, the amount of power supplied from the solar power generation facility to the power transmission / distribution facility is regarded as the amount of power generated by the solar power generation of each consumer according to the pre-registered and stored distribution amount. It is. That is, each consumer can be regarded as performing solar power generation without actually installing solar power generation equipment in his own house or the like. Since the surplus power amount of each consumer is calculated based on the power generation amount and the power consumption amount, the surplus power amount can be sold to an electric power company or the like.

  In this way, it is possible to obtain the amount of power generated by solar power generation as if it were installed with solar power generation equipment, and to sell the surplus power, so that anyone can use it regardless of the living environment. It is possible to enjoy the benefits of solar power generation. In addition, since there is no need for individual customers to install solar power generation facilities, rain leaks and roof damage do not occur, maintenance and management of solar power generation facilities, and countermeasure work for rising power system voltage, etc. There is no need to do. Furthermore, since many photovoltaic power generation facilities are not installed in a decentralized manner, the power quality does not deteriorate and it is not necessary to carry out countermeasure work for that purpose. As a result, it is possible to promote the use of solar power generation by each household. Here, the amount of power that is the basis for the amount of money that the power company charges each customer as a power charge is calculated by integrating the amount of power consumed by each consumer that exceeds the amount of generated power.

  According to the second aspect of the present invention, the ratio of the self-power consumption amount of each individual consumer to the total self-power consumption amount generated by the solar power generation facility and consumed by each consumer is calculated.

  The present invention will be described below based on the illustrated embodiments.

  FIG. 1 is a schematic configuration diagram showing a solar power generation facility distribution system 1 according to an embodiment of the present invention. The solar power generation facility distribution system 1 is a system for distributing the rights of the solar power generation facility 2 to a plurality of consumers / users U. The solar power generation facility 2, the solar operator server 3, A power transmission / distribution facility (power supply facility) 4, a power company server 5, and a power meter (measuring means) 6 are provided. Here, the solar power generation facility 2 and the solar operator server 3 are owned by the solar operator SC that installs and operates the solar power generation facility 2 and provides a distribution service, the power transmission / distribution facility 4 and the electric power company server. 5 is assumed to be owned by a power company PC that supplies power to each consumer U.

  The solar power generation facility 2 is a large-scale power generation facility in which a large number of solar modules are arranged and generates power using sunlight. The solar power generation facility 2 is connected to the power transmission / distribution facility 4 to transmit all generated power to the power transmission / distribution facility. Supply to 4 and reverse power flow. Here, a part of the generated power may be consumed by the solar operator SC, and the remaining power may be supplied to the power transmission and distribution equipment 4. In this case, the amount of power supplied to the power transmission / distribution facility 4 becomes “amount of power generated by the photovoltaic power generation facility 2” in the power amount task 54 described later. Moreover, the electric power generation value by the solar power generation equipment 2 is transmitted to the solar business operator server 3 sequentially and in real time.

  The solar company server 3 is a computer that accepts an application for a condominium service from each customer U, and charges each customer U for the cost required for the management and operation of the solar power generation facility 2, as shown in FIG. In particular, the communication unit 31, a first customer database (distributed amount storage means) 32, a registration task (registration means) 33, a cost burden task (cost calculation means) 34, and a self-consumption task (self-consumption) Calculation means) 35 and a central processing unit 36 for controlling these.

  The communication unit 31 is a communication device for communicating with the power company server 5 and the information communication terminal (not shown) of each customer U via the communication network NW.

  The first consumer database 32 is a database that stores information related to the consumer U who has a contract for a sale of distribution service. As shown in FIG. 3, for each contract number 321, a customer name 322, an address 323, An electric power company 324, a sales amount 325, self-consumption power 326, a cost burden 327, and others 328 are stored.

  Specifically, the customer name 322 stores the name of the contracted customer U, and the address 323 stores the location of the customer U's home. The power company 324 stores the company name of the power company to which the consumer U is receiving power supply, and the sales amount 325 includes this demand out of the power generated by the solar power generation facility 2 as described later. A power value (distributed amount) indicating a ratio assigned as generated power by the house U is stored. As will be described later, the self-power consumption 326 stores power data (self-power consumption) consumed by the customer U's power generated by the consumer U, and the cost burden 327 includes the solar power generation facility 2. Of the expenses required for the management operation, the cost burden that the customer U should bear is stored.

  Such a contract number 321, customer name 322, address 323, power company 324, and sales amount 325 are registered / stored in the registration task 33, and the self-power consumption 326 is power as described later. Upon receipt of data transmission by the power amount task 54 of the company server 5, registration and storage are performed. The expense burden 327 is registered and stored in the expense burden task 34.

  The registration task 33 is a program that receives an application from each customer U, and registers the amount of distribution by application in the first customer database 32 within a preset range, and is based on the flowchart shown in FIG. . Here, the customer U starts the registration task 33 by accessing a Web page provided by the solar business operator server 3 when applying for the sale for sale.

  First, an application screen for inputting and inputting information required for the contract for the sale service is output (step S1). Here, the information required for the contract includes, in addition to the name and address of the consumer U, the name of the electric power company to which the consumer U is receiving power supply and the desired sales amount. Input is possible in units. Next, when the customer U inputs information such as the sales amount on the application screen (step S2), it is determined whether or not the input power company is a power company PC that is connected to and contracted with the solar operator SC. (Step S3). This is because if the solar power generation facility 2 is not a power company PC of the power transmission / distribution facility 4 that is grid-connected, it is not possible to supply power from the solar power generation to the power transmission / distribution facility 4. In this embodiment, the customer Surplus power to be described later can be sold only to the power company PC to which U is supplied with power. Here, when the solar operator SC has a plurality of solar power generation facilities 2 and the power company PCs connected to the grid are different for each of the solar power generation facilities 2, one of the power company PCs is input. To determine whether or not the power company.

  If the result of step S3 is that the power company PC is not linked, a message indicating that the service cannot be provided is output (step S4). Is determined whether or not is appropriate (step S5). That is, in this embodiment, the upper and lower limit values (for example, 1 to 5 kW) of the sale amount that can be contracted are set in advance, and it is determined whether or not the inputted sale amount is within this upper and lower limit value. In addition, when the customer U has already installed the solar power generation facility in his / her home, a message indicating that the service cannot be provided is output as in step S4. Here, this determination is made by inquiring whether or not the photovoltaic power generation facility is installed to the power company server 5 of the power company PC in which the presence or absence of the installation (power sale contract) of the photovoltaic power generation facility is stored.

  As a result of step S5, when the inputted sale amount is not appropriate, the process returns to step S1 and waits for the input again. On the other hand, if the input amount is appropriate, the input information is registered and input with the contract number added to the first customer database 32 (step S6). Furthermore, the name, address, and amount of sale of the customer U are transmitted as registration data to the power company server 5 of the power company PC input in step S1 (step S7).

  The cost burden task 34 calculates the cost burden allocated to each consumer U based on the cost required for the management and operation of the photovoltaic power generation facility 2 and the amount of sales stored in the first consumer database 32. It is a program. Specifically, the total cost required for the operation, maintenance, land use, etc. of the solar power generation facility 2 and the total power generation capacity of the solar power generation facility 2 are preset and stored, and based on the total cost and the total power generation capacity The cost share per unit power (unit share) is calculated. Then, the unit share is multiplied by the sales amount of the consumer U, the expense share of the consumer U is calculated, and is registered and input into the expense burden 327 of the consumer database 32.

  Such a cost burden task 34 is activated after the registration task 33 is activated, that is, after the application for the distribution service is performed, and is calculated for the customer U who has applied. Or it starts, when the total expense required for management administration of the photovoltaic power generation equipment 2 is changed, and it calculates with respect to all the consumers U as needed. Further, as will be described later, a bill is issued and sent to each customer U based on the cost burden calculated by the cost burden task 34 every month.

  The self-consumption task 35 is a program that calculates a self-consumption ratio indicating the ratio of the self-consumption power amount of each customer U to the total self-consumption power amount based on the self-consumption power amount stored in the self-consumption power 326. . Here, although self-consumed electric energy is mentioned later, it shows the electric energy consumed by this consumer U among the generated electric power considered as the electric power generation by the consumer U.

  Specifically, the total self-power consumption is calculated by adding the self-power consumption of all the consumers U in the solar power generation facility 2, and the self-power consumption of each consumer U with respect to this total self-power consumption The ratio is calculated as a self-consumption ratio, and the calculation result is stored in the other 328 of the first consumer database 32. As will be described later, such a self-consumption task 35 is started when the profit from the green power certificate is returned to each consumer U, and for each consumer U based on the calculated self-consumption ratio. The refund will be returned.

  The power transmission / distribution facility 4 is a facility for supplying power to each consumer U, and includes a power transmission line, a distribution line, a substation facility, and the like, and is usually provided for the power company PC to supply power to each consumer U. Equipment. Moreover, it is grid-connected with the solar power generation facility 2, receives the power reversely flowed from the solar power generation facility 2, and sequentially transmits the amount of power to the power company server 5.

  The power meter 6 is a meter that is provided in each customer U's home and measures the amount of power consumed in the customer U's home, has a communication function, and sequentially sends the measurement result via the communication network NW to the power company server 5. To be sent to.

  The electric power company server 5 is a computer that calculates the power generation amount and surplus power amount of each customer U. As shown in FIG. 5, the power company server 5 mainly includes a communication unit 51 and a second customer database (distributed amount storage means). ) 52, a solar database 53, a power amount task (power amount calculation means) 54, and a central processing unit 55 for controlling these.

  The communication unit 51 is a communication device for communicating with the solar operator server 3, the power meter 6 of each customer U, the information communication terminal, and the like via the communication network NW.

  The second customer database 52 is a database that stores information related to the customer U who has a contract for the distribution service. As shown in FIG. 6, for each contract number 521, a customer name 522, an address 523, A solar company 524, a sales amount 525, power consumption 526, and others 527 are stored.

  Specifically, the customer name 522 stores the name of the contracted customer U, and the address 523 stores the location of the customer U's home. The solar company 524 stores the name of the operator of the solar operator SC to which the consumer U is receiving the sale service, and the sale amount 525 stores the power value assigned as the power generation by the consumer U. Yes. The power consumption 526 stores power data consumed in the consumer U's home. Specifically, as shown in the consumption line L1 in FIG. 7, the power consumption of each time on each day is stored.

  Such customer name 522, address 523, solar company 524, and sales amount 525 are registered and stored when the registration data is received from the registration task 33 of the solar operator server 3 as described above. The power consumption 526 is registered and stored each time a measurement result is received from the power meter 6 of each consumer U.

  The solar database 53 is a database that stores the amount of power and the reverse power flow supplied from the photovoltaic power generation facility 2 to the power transmission and distribution facility 4, and receives and registers and stores the amount of power from the power transmission and distribution facility 4. Specifically, the generated power for each hour on each day is stored.

  The power amount task 54 calculates a consumer power generation amount regarded as a power generation amount by each consumer U based on the power generation amount by the solar power generation facility 2 and the sales amount stored in the second consumer database 52. This is a program for calculating the surplus power amount of each customer U based on the consumer power generation amount and the power amount measured by the power meter 6, and is based on the flowchart shown in FIG.

  First, the amount of power generated by the solar power generation facility 2 is acquired from the solar database 53 (step S11), and the amount of sales for the first customer U is acquired from the second customer database 52 (step S12). Next, based on the acquired power generation amount and the sale amount, the customer power generation amount regarded as the power generation amount by the customer U is calculated (step S13). That is, the ratio / ratio of the sales amount to the total power generation capacity of the solar power generation facility 2 is calculated, and the actual power generation amount by the solar power generation facility 2 is multiplied by this ratio to calculate the customer power generation amount. Thereby, for example, as shown in the power generation line L2 in FIG. 7, the generated power regarded as the power generation by the consumer U is obtained.

  Here, in this embodiment, since all the power generated by the solar power generation facility 2 is supplied to the power transmission / distribution facility 4 as described above, the amount of power generated by the solar power generation facility 2 is directly supplied to the power transmission / distribution facility 4. The amount of power supplied. On the other hand, when a part of the power generation amount by the solar power generation facility 2 is supplied to the power transmission and distribution facility 4, the power generation amount by the solar power generation facility 2 means the amount of power supplied to the power transmission and distribution facility 4. To do.

  Subsequently, the power consumption data of the consumer U is acquired from the second consumer database 52 (step S14), and the surplus power amount, the self power consumption amount, and the purchased power amount are calculated (step S15). That is, as shown in FIG. 7, the generated power (power generation line L2) calculated in step S13 and the acquired power consumption (consumption line L1) are overlapped. And among the electric energy enclosed by the power generation line L2, the electric energy (the part of only the right hatching in the figure) which is not enclosed by the consumption line L1 is calculated as the surplus electric energy P1. This surplus power amount P1 is the amount of surplus power that has not been consumed in the home out of the power generated by the home.

  Further, among the electric energy enclosed by the power generation line L2, the electric energy enclosed by the consumption line L1 (the portion where the right hatching and the left hatching are mixed in the figure) is calculated as the self-consumed electric energy P2. This self-consumed power amount P2 is the amount of power consumed by one's own power out of the power generated by the home (during self-power generation). Further, among the electric energy enclosed by the consumption line L1, the electric energy not enclosed by the power generation line L2 (the part with only the left hatching in the figure) is calculated as the purchased electric energy P3. This purchased power amount P3 is the amount of power consumed by power that is not generated by the house.

  Such a calculation of the surplus power amount P1 and the like is performed for each day of a predetermined period. Specifically, it is performed for all days of the current month, and the results of each day are summed to calculate the surplus power amount P1 for the current month. And these calculation results are memorize | stored in the others 527 of the 2nd consumer database 52 (step S16).

  Next, when the processing for all the consumers U has not been completed (in the case of “N” in step S17), the sales amount of the next consumer U is acquired from the second consumer database 52 (step S1). S18), the processing of steps S13 to S16 is repeated. On the other hand, when the processing for all the consumers U is completed (in the case of “Y” in Step S17), the self-power consumption P2 of all the consumers U is transmitted to the solar operator server 3 (Step S19). It is.

  Such a power amount task 54 is started monthly, and based on the surplus power amount P1, the self-consumed power amount P2, and the purchased power amount P3 calculated as described above, billing of a power charge as described later is performed. Etc. are performed. Further, as described above, in step S15 of the power amount task 54, the self-power consumption amount P2, which is a process as self-consumption calculation means, is calculated. This is calculated by the solar operator server 3. This is because data of power consumption (consumption line L1) is required. That is, in order to prevent the flow of power consumption information of each consumer U, but when there is no such problem, the power consumption data is transmitted to the solar business server 3, and the solar business server 3 Thus, the self-power consumption amount P2 may be calculated. Alternatively, the power consumption task 54 may be provided with a self-consumption calculation means, calculate the self-consumption ratio of each consumer U, and transmit the calculation result to the solar operator server 3.

  Next, the effect | action of the solar power generation equipment distribution system 1 of such a structure is demonstrated based on FIG. Here, it is assumed that the application for the distribution service has already been performed, and as described above, the registration task 33 is activated and the distribution amount is stored, and the expense sharing task 34 is activated and the expense sharing is stored. .

  First, the power generated by the solar power generation facility 2 is supplied to the power transmission / distribution facility 4 and reversely flowed (step S21), and the measured power amount is sequentially stored in the solar database 53 of the power company server 5 (step S22). . On the other hand, power is supplied from the power transmission / distribution facility 4 to each customer U (step S23), and the amount of power consumption is measured by the power meter 6 (step S24). Then, the measurement result is sequentially transmitted from the power meter 6 to the power company server 5 (step S25), and this power consumption is stored in the second consumer database 52 (step S26).

  In such a state of power generation and power consumption, the power amount task 54 is started at a predetermined time every month (step S27), and as described above, the surplus power amount P1, the self power consumption amount P2 of the current month for each consumer U, and The purchased power amount P3 is calculated. Further, the calculated self-power consumption amount P2 is transmitted to the solar provider server 3 (step S28), the self-consumption task 35 is activated (step S29), and the self-consumption ratio of each consumer U is calculated. Here, the activation of the self-consumption task 35 may be performed at the time of selling the environmental value described later (step S33).

  Next, at a predetermined time, based on the calculated surplus power amount P1, the power company PC pays a purchase fee (power selling fee) to each customer U (step S30). That is, a purchase fee obtained by multiplying the surplus power amount P1 by the unit price of the power sale fee is paid. Subsequently, based on the calculated power purchase amount P3, the power company PC charges each customer U for a power charge (power purchase charge) (step S31). That is, a power charge obtained by multiplying the purchased power amount P3 by the unit price of the purchased power charge is charged. Here, based on the surplus power purchase system, the unit price of the power sale fee is set higher than the unit price of the power purchase fee.

  In addition, at a predetermined time, the solar business operator SC charges each customer U for the cost burden required for the management and operation of the solar power generation facility 2 (step S32). That is, each customer U is charged based on the cost burden calculated and stored by the previous cost burden task 34. On the other hand, of the amount of power generated by the solar power generation facility 2 (the amount of power supplied to the power company PC), the amount of power that has not been distributed to the consumer U is transferred from the power company PC to the solar operator SC at a predetermined unit price. A purchase fee is paid.

  Furthermore, when the solar power supplier SC converts the self-power consumption amount into a green power certificate and sells it to a third party as an environmental value (step S33), the obtained profit is returned to each customer U (step S34). ). Specifically, the profit obtained by selling is distributed to each consumer U based on the self-consumption ratio calculated in the previous self-consumption task 35. That is, it distributes more to each customer U with a high self-consumption ratio, and returns such refund to each customer U. Here, the green power certificate is a certificate that can be traded for the environmental added value of power obtained from renewable energy.

  As described above, according to the solar power generation facility distribution system 1, the power generation by the solar power generation facility 2 is regarded as the solar power generation of each consumer U according to the distribution amount of each consumer U. That is, each consumer U can sell the same profit as installing a solar power generation facility, that is, surplus power without actually installing the solar power generation facility in his own house, You can receive a return of profits from the certificate.

  In this way, by receiving this distribution service, it is not necessary for each customer U to install a solar power generation facility, and anyone can install the solar power generation facility at any time regardless of the living environment. It is possible to enjoy the benefits of solar power generation. In addition, in the consumer U's house, there is no leakage or damage to the roof, and it is not necessary for each consumer U to maintain and manage the solar power generation facility. Furthermore, since the solar operator SC collectively performs voltage countermeasures, the power generation amount is not suppressed by the rise of the power system voltage, and similarly, the solar power generation facilities 2 are concentrated and installed. It becomes possible to manage power quality easily and appropriately. Moreover, it becomes possible to evaluate appropriately the contribution with respect to the environment by each consumer U by return of the profit by electric power sale or green electric power certification. In addition, since the solar operator SC collects the green power certificate in a lump, the cost of the certificate can be reduced. As a result, it is possible to promote the use of solar power generation by each household.

  On the other hand, since each customer U bears the cost share according to the amount of sales, it is possible to enjoy the benefits of solar power generation without individually installing solar power generation facilities. In addition, since the cost share corresponding to the amount of sale, that is, the amount of power generation is calculated, the cost burden is determined according to the profit from the solar power generation, and fairness among the consumers U can be ensured. Moreover, since the sales amount is registered by the application from each consumer U, each consumer U can obtain a desired power generation amount and profits from solar power generation. Moreover, since the sales amount can be registered within preset upper and lower limits, it is possible to prevent only a specific consumer U from enjoying the benefits of solar power generation and to use solar power generation by more households. Can be promoted.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the above embodiment, it is assumed that the power transmission / distribution facility 4 of the power company PC that supplies power to the consumer U is linked to the solar power generation facility 2 of the solar operator SC. Even if the power transmission / distribution facility 4 and the solar power generation facility 2 are not directly linked, the present system 1 can be applied. That is, by transmitting and receiving information and data such as generated power and power consumption, it is possible to calculate surplus power and self-power consumption, and to make various charges. Further, although the amount of sale is registered in units of kW, the percentage of the entire right of the solar power generation facility 2 may be registered. Furthermore, you may make it set the amount of distribution to each consumer U based on the living environment of each consumer U. For example, set the amount of sales based on the amount of power generation expected to be obtained when installing solar power generation facilities at the target consumer's U home, or generate power from neighboring residents who have already installed solar power generation facilities A sale amount may be set based on the amount.

By the way, the following solar power generation facility sales program may be installed in the computer of the electric power company PC or the solar operator SC to obtain the same operation and effect as the present system 1. That is,
Computer
