Description

The present invention relates to an electric power trading platform, and more specifically, it is possible to buy and sell electric power of a company, a local government, etc. from a small private house at an appropriate fixed price, and while establishing the use of the environmental value contained in the electric power. It is about an electricity trading platform that can trade both electricity and environmental value.

Although the liberalization of electricity has been done, the majority of households of ordinary individuals have individually signed contracts with major electric power companies to purchase electricity. In addition, the electricity rate for individuals of the major electric power company is almost twice as high as the electricity rate for industry, and it is a metered lamp rate system that becomes expensive when a lot of electricity is used.

In Japan, solar power generation systems are currently installed in about 2.3 million homes. Regarding surplus electricity from power generation facilities of less than 10 kW for residential use, electric power companies, etc. at a fixed price for 10 years according to the "Act on Special Measures Concerning the Procurement of Renewable Energy Electricity by Electricity Companies" (hereinafter referred to as the "FIT System"). Is buying from an individual.

After the end of the 10-year purchase period under the FIT system, it is expected that the power generated by the photovoltaic power generation system will be oversupplied rather than demanded. As a result, general individuals who have a solar power generation system will newly conclude a surplus power purchase contract with an electric power company, etc., but the price is as low as 10 yen / kW from the current fixed price (24 yen / kW). It is expected to be purchased at.

The surplus electricity of private houses with solar power generation is derived from solar power generation and includes non-fossilized value (hereinafter referred to as "environmental value"), but there is a market that is certified and traded as environmental value until now. Not. In addition, the liberalization of the low-voltage electricity retail business in 2016 has created hundreds of electricity retailers (hereinafter referred to as "new electricity"). According to the Electricity Business Act revised in 2015, the new electric power is obliged to manage the supply and demand of electric power in accordance with the principle of simultaneous equal amount for 30 minutes, and in 2016, it is amended to obligate the same amount at the planned site.

However, the power generated by the photovoltaic power generation system of a private house fluctuates due to solar radiation, and the power consumption of the private house also fluctuates from moment to moment. Therefore, the surplus power cannot be predicted accurately, and it is extremely difficult to balance the supply and demand according to the same amount of the planned values at the same time. Therefore, the new power will be procured from the Japan Electric Power Exchange (hereinafter referred to as "JEPX") in anticipation of the amount of power transmitted the next day. At that time, if the same amount of planned values cannot be observed and deviates, an imbalance penalty will be imposed. Furthermore, since the wholesale electricity price of JEPX fluctuates from moment to moment, the management of new electricity becomes unstable. In addition, JEPX conducts large-lot (500 kW or more) electricity transactions, but does not carry out small-lot (less than 500 kW) electricity transactions. In this way, there is no market for buying and selling surplus electricity and environmental value of individuals (small lots) until now.

By the way, a storage unit that stores consumer information including power consumption for at least one load device of the consumer, a receiver that receives a request signal for power saving, and a consumer information by receiving the request signal. A selection unit that selects consumers who want to request power consumption reduction using the method, a transmission unit that sends guidance information on power consumption reduction to the communication equipment of the selected consumer, and at least one of the selected subscribers. Demand by a server equipped with a monitoring unit that monitors the power consumption by one load device and a compensation management unit that grants a predetermined compensation to the consumer when the power consumption by the load device decreases according to the guidance information. A power consumption management method for managing the power consumption of a house is known (see, for example, Patent Document 1).

In addition, it manages the amount of power generated and consumed by the solar power generation system and the amount of surplus power sold, calculates the amount of carbon dioxide emission credits sold, and sells them to other consumers, as well as carbon dioxide emissions. The right will be securitized or virtual currency, and the consideration to be exchanged equivalent to the carbon dioxide emission credit will be obtained, and the return value will be given as points (points or virtual currency) that can be exchanged for the specified value or service. A carbon dioxide emission trading system and a carbon dioxide emission trading method are known (see, for example, Patent Document 2).

As mentioned above, it is difficult to accurately predict the power generated by the photovoltaic power generation system installed in a private house, the power consumption of consumers, and the surplus power. There is the problem that it is extremely difficult to comply with management. Therefore, after the end of the current FIT system, it will be difficult to buy and sell surplus electricity at a predetermined price in the market. Furthermore, there is no market for buying and selling small amounts (less than 500 kW) of surplus electricity and environmental value.

In addition, a power meter (hereinafter referred to as "smart meter") 22 for measuring the sold power PQ3 sold via the power trading platform 10 (power network 11) or the purchased purchased power PQ4, and the solar power generation system PV generated power. The energy management device (hereinafter referred to as "HEMS") 23 that calculates the shortage power or the surplus power while measuring the power amount PQ1, the smart meter 22, the HEMS 23, and the orthogonal flow converter 21 are controlled and on the computer network 12. The server 13 or a computer 24 that communicates with 20, 30, 40 computers such as other consumers.

The electric power PQ1 generated by the photovoltaic power generation system PV is stored in the storage battery BT. The stored electric power PQ1 is weighed by the HEMS 23 and stored in the storage unit 23a built in the HEMS 23. When the electric power PQ1 stored in the storage battery BT is used, it is converted into a predetermined AC electric power via the orthogonal flow converter 21 and then supplied to the load device 25 in the home or the building, or the electric power network 11 It is supplied (sold) to other consumers, etc. 20, 30, 40 via the system. The power consumption PQ2 consumed by the load device 25 in the home or the building, and the power consumption PQ3 sold via the power network 11 or the purchased power PQ4 purchased are measured by the smart meter 22 and the smart meter 22 is used. It is stored in the built-in storage unit 22a.

The smart meter 22 and the HEMS 23 have a communication function capable of communicating with the computer 24. As a result, the generated power PQ1 generated by each photovoltaic power generation system PV, the power consumption PQ2 used by each consumer, the sold power PQ3 sold by 20, 30, 40 such as each consumer, and the purchased power purchased. The quantity PQ4 is taken in by the computer 24 and recorded in the storage unit 24a. In the electric power trading platform 10, this storage unit 24a also functions as a virtual ledger, and the electric power transaction data (sales power amount PQ3, purchased power amount PQ4, etc.) described in the virtual ledger is other than the owner of the computer 24. It is configured so that it can be referred to by other consumers such as 20, 30, and 40.

The data analysis unit 13b is a data analysis device based on artificial intelligence (AI) technology specialized in analysis / prediction of time series data.

As a result, the electric power trading platform 10 can manage the supply and demand of electric power with high accuracy. As a result, it becomes possible to stably carry out the supply and demand management of electric power (the total amount in 30-minute units is the same amount at the same time), which is legally required.

FIG. 3 is an explanatory diagram showing the main business of the operator 60 that operates the electric power trading platform 10 according to the present invention.
The operator 60 manages the power supply and demand of 20, 30, and 40 for each consumer and the like. That is, the operator 60 analyzes the generated power PQ1 and the power consumption PQ2 of each consumer, etc. 20,30,40 by using the data analysis device based on the artificial intelligence (AI) technology, and the purchased power amount PQ4. Make a prediction.

In addition, the operator 60 manages a distributed ledger based on the blockchain technology (FIG. 4) for all electric power trading transactions (sales electric energy PQ3, purchased electric energy PQ4). Clearing is done on a monthly basis, for example. In addition to virtual currency, ordinary currency can also be used in this settlement.

In addition, the operator 60 issues and manages the environmental value included in the surplus electricity as a green power certificate or the like. Green power certificates and the like are traded with virtual currency or valuables on the power trading platform 10.

In addition, the operator 60 requests each consumer, etc. 20, 30, 40 to make a demand response or negawatt transaction that promotes power saving. Specifically, the server 13 (FIG. 2) constantly monitors the purchased electric energy PQ4 of each consumer, etc. 20, 30, 40 via the smart meter 22 (FIG. 2), and at the peak of electric power use. Instructs the consumer computer 24 (FIG. 2), which has a large amount of purchased power PQ4, to execute a demand response. The computer 24 that receives the command reduces the purchased electric energy PQ4 via the smart meter 22.

In addition, the operator 60 requests each consumer, etc. 20, 30, 40, to have a system (electric power transaction service) in which neighboring consumers, etc. exchange electric power with each other. Specifically, the server 13 (FIG. 2) sells the surplus power PQ3 to the power trading platform 10 to the consumer computer 24 having a large surplus power PQ3, for example, when the power generation amount of the power generator 50 decreases. Command. Upon receiving the command, the computer 24 converts the DC power stored in the storage battery BT via the orthogonal flow converter 21 into a predetermined AC power PQ3 and sells it to the power trading platform 10 via the smart meter 22.

In this way, the operator 60 predicts the purchased power PQ4 of each consumer, etc. 20, 30, 40 based on the AI technology, and executes the demand response, negawatt trading, or power trading service when the power is insufficient. And carry out the legally mandated supply and demand management of electricity.

4 and 5 are conceptual diagrams showing distributed ledger management of the electric power trading platform 10 according to the present invention. FIG. 4 shows the computer network 12 according to the present invention. FIG. 5 shows the blockchain data according to the present invention.
As shown in FIG. 4, the first computers 24-1, ..., The nth computers 24-n of each member are equally connected by P2P (Peer To Peer). Therefore, for example, regarding the ledger information 1 stored in the first storage unit 24a-1 connected to the first computer 24-1, the second computer 24-2, ..., No. 1 other than the first computer 24-1. It can be freely viewed via n-computer 24-n. Further, about the electric energy data (generated electric energy PQ1, power consumption PQ2, sold electric energy PQ3, purchased electric energy PQ4) stored in the first smart meter (SM) 22-1 and the first HEMS23-1. Also, it can be freely viewed via the second computer 24-2, ..., The nth computer 24-n other than the first computer 24-1.

An application for managing distributed ledgers based on blockchain technology is pre-installed on each computer 24-1, ..., 24-n. Therefore, the k-th transaction (ledger information k) related to the electric power transaction created by the k-th computer 24-k is recorded in the k-th storage unit (k-th virtual ledger) 24a-k of the computer 24-k, and is the first. It is transmitted to computers 24-1, ..., 24- (k-1), 24- (k + 1), ..., 24-n other than the k computer. Then, regarding the kth transaction (ledger information k), computers other than the kth computer 24-1, ..., 24- (k-1), 24- (k + 1), ..., 24- Validated and approved by n. Transactions (ledger information) related to power transactions that are not included in the verified / approved existing block are newly combined into one block by the computer in charge of blockchain creation, and chained to the existing block. And shared by each computer 24-1, ..., 24-n. As for the computer that creates the block, it is possible to select the computer that first searches for the parameter (nonce value) that makes the output value (hash value) of the hash function equal to or less than a predetermined value (threshold value). The generation of blocks will be described below.

As shown in FIG. 5, each block has a "transaction (ledger information)" in which a transaction for buying and selling electric power is described, a "hash value" which is an output value of a hash function, and a "nonce value" which is a parameter of the hash function. It is composed of. The hash function has three parameters, "the hash value of the previous block", "the nonce value", and "the transaction added to this block". For example, when generating the N + 1 block (power trading transaction at N + 10:00), the Nth hash value of the Nth block is used for the “hash value of the previous block”. For the "transaction added to this block", the transaction information (ledger information 1', ..., ledger information n') traded between N:30 and N + 10:00 is used. As for the "nonce value", a value such that the output value of the hash function when the nonce value is assigned to the hash function is equal to or less than the threshold value is used as the N + 1 nonce value. In this way, the hash function required to create a block uses the "hash value of the previous block", so for example, if the transaction (ledger information) of a certain block is changed, the hash after that. All values will be changed. Therefore, in distributed ledger management based on blockchain technology, data falsification becomes extremely difficult.

The created N + 1 block is connected to the end of the Nth block and chained. All the blocks (blockchain data) connected in a chain are stored in the storage unit 13a of the server 13 of the operator 60. Here, when the server 13 is the company's own server, the blockchain data is stored in the company's data center. Alternatively, if the server 13 is a cloud server, it is stored in the data centers of the company or another company provided in various places. In addition, all the information related to power generation such as the origin of solar power generation, the amount of power generation, and the time of power generation will be added to the ledger information related to the transaction of buying and selling electric power.

As described above, according to the electric energy trading platform 10 according to the present invention, since each member 20, 30, 40, 50 includes a storage battery BT, fluctuations in the generated electric energy PQ1 and the electric energy consumption PQ2 are suppressed, and the fluctuations are suppressed. For the purchased electric energy PQ4 of each consumer, etc. 20,30,40, each consumer, etc. 20,30,40, using a data analyzer based on artificial intelligence (AI) technology specialized in analyzing time-series data. It is configured to analyze the generated electric energy PQ1 and the electric energy consumption PQ2 of the 40 and predict the purchased electric energy PQ4. Further, the operator 60 is configured to be able to request demand response, negawatt transaction and electric power transaction service from each consumer and the like 20, 30, 40. This makes it possible to stably manage the supply and demand of electric power, which is legally required.

In addition, electricity transactions between members are managed by a distributed ledger based on blockchain technology. As a result, maintenance costs related to electric power transactions will be significantly reduced, and at the same time, fraud such as data falsification will be prevented and transparency and safety of electric power exchanges will be guaranteed. As a result, it becomes possible to buy and sell surplus electricity of 20, 30, and 40 for each consumer at a predetermined fixed price.

In addition, by making it possible to exchange the environmental value for a green power certificate or virtual currency, it is possible to effectively utilize the environmental value included in the surplus electricity. This will greatly contribute to the reduction of carbon dioxide emissions on a global scale.
