Fig. 2 is a schematic diagram of a power transaction system based on a blockchain according to the present embodiment. Referring to fig. 2, the system includes: the system comprises a blockchain system 200 running a blockchain, a server 300 connected with the blockchain system 200 in a communication mode and provided with a prediction machine, and terminal equipment 110-140 of a plurality of users 101-104 which can access the blockchain system 200. For example, but not limited to, the user 101 may be a power demand party 101, and the users 102-104 are all power supply parties 102-104.
Specifically, in a case where the power demand party 101 (e.g., a certain school) has a demand for power, the relevant demand for power information may be transmitted to the blockchain system 200 through the terminal device 110. Similarly, when the power suppliers 102 to 104 sell the electricity generated by the personal microgrid devices, the corresponding power supply demand information may be transmitted to the blockchain system 200 through the respective terminal devices.
Further, the blockchain running on the blockchain system 200 is pre-deployed with intelligent contracts related to power transactions. In the transaction matching stage, after receiving the power consumption demand information and the power supply demand information from the terminal devices of the participants, the blockchain system 200 calls an intelligent contract to match the transaction, and after determining both transaction parties, generates a transaction order and stores the transaction order to the blockchain. In the transaction execution phase, transaction data (e.g., power internet of things (IoT) device data and trusted data source data) related to the transaction is collected by the server 300 with the prediction machine deployed, and the collected data is sent to the blockchain system 200. So that the intelligent contract in the blockchain system 200 can determine whether the two parties of the transaction execute the corresponding transaction operation according to the transaction data received from the server 300 with the prediction machine deployed. The trusted data source data is used for indicating that the trusted data source data is directly collected from a data source, calculated and transmitted in an encryption mode to obtain a data calculation result.
It should be noted that the above-mentioned hardware structure can be applied to the blockchain system 200, the server 300 and the plurality of terminal devices 110 to 140 in the system.
In the above operating environment, according to the first aspect of the present embodiment, there is provided a power transaction method based on a blockchain, which is applied to a blockchain system operating a blockchain, and the method is implemented by the blockchain system 200 shown in fig. 2. Fig. 3 shows a flow diagram of the method, which, with reference to fig. 3, comprises:
s302: receiving power demand information including power demand of a power demand party;
s304: calling an intelligent contract which is pre-deployed on a block chain, and determining a target power supplier corresponding to the power demand information from a plurality of power suppliers; and
s306: generating trade orders related to the power demand side and the target power supply side, and storing the trade orders to the blockchain.
As mentioned in the background section above, with the popularity of micro-grids (solar, wind, photovoltaic, and gas turbines, etc.), the need for personal energy management and trading has grown enormously. However, since the market does not have a trading framework of personal electricity, the personal energy owner cannot conveniently customize a trading plan, and needs to be affiliated with the electric power company (registered in the website or APP of the electric power company), the individual cannot monitor and manage the capacity of the micro-grid under the name of the individual and trade for profit, and the individual does not have a price negotiation right. Moreover, as the information in the electric power transaction process is opaque, and the transaction data is easily tampered by others, the fairness, the justice and the reliability of the transaction are difficult to guarantee. This greatly inhibits the widespread use of personal energy sources and the interest of individuals in investing in microgrid.
In view of the problems in the background art, as shown in fig. 2, in the present embodiment, a blockchain system 200 runs a blockchain, and intelligent contracts related to power transactions are pre-deployed on the blockchain. In the case where the electricity demander 101 (e.g., a school) has an electricity demand, the relevant electricity demand information may be transmitted to the blockchain system 200 through the terminal device 110. At this time, the blockchain system 200 receives the power demand information including the power demand of the power consumer 101. The power demand information may include, for example, but not limited to, information such as electricity consumption time, electricity consumption amount, and expected power price. Thus, the personal energy source owner can conveniently customize the transaction plan.
Further, when the power suppliers 102 to 104 sell the electricity generated by the personal microgrid devices, the corresponding power supply demand information may be transmitted to the blockchain system 200 through the respective terminal devices. Therefore, the blockchain system 200 calls an intelligent contract pre-deployed on the blockchain to determine a target power supplier corresponding to the power demand information from the plurality of power suppliers 102-104. Therefore, a transaction framework of the personal power is provided, and by calling the intelligent contracts deployed on the blockchain, transaction matching can be performed in a decentralized environment according to supply and demand requirements of supply and demand parties. It should be noted that the determined target power supplier may be one power supplier (e.g., the power supplier 102) or a plurality of power suppliers (e.g., the power supplier 102 and the power supplier 103), and is not limited herein.
Further, upon determining the trading partners, the blockchain system 200 generates a trade order related to the electricity consumers 101 and the target electricity provider (e.g., the electricity provider 102), and then stores the trade order to the blockchain based on the data stored on the blockchain having non-falsifiable and publicly transparent characteristics. Therefore, through the operation of storing the transaction order in the block chain, the personal energy source owner can conveniently retrieve and verify the transaction information, and the fairness, the justice and the reliability of the transaction between the power demand side 101 and the power supply side 102 are guaranteed.
Therefore, the electric power transaction method based on the blockchain provided by the embodiment combines the blockchain technology and the intelligent contract technology, and provides a set of transaction framework which is automatically executed by the intelligent contract and is based on the blockchain for the personal energy source owner, so that the personal energy source owner can conveniently customize a transaction plan, match the transactions in a decentralized environment, and store the transaction orders in the blockchain, so that the information in the transaction process is transparent and can not be falsified, and the fairness, the justice and the reliability of the electric power transaction are guaranteed. Thereby greatly promoting the popularization and the use of personal energy and the interest of personal investment in the microgrid. And the technical problems that in the prior art, due to the fact that a personal electric power trading framework is not available in the market at present, a human energy owner cannot conveniently customize a trading plan, information in the electric power trading process is opaque, trading data are easily tampered by others, and fairness, justness and reliability of trading are difficult to guarantee are solved, so that the popularization and the use of personal energy and the interest of personal investment in a microgrid are greatly inhibited.
Optionally, the operation of the intelligent contract, which stores a transaction matching algorithm in advance and calls the intelligent contract deployed on the blockchain in advance, to determine a target power supplier corresponding to the power demand information from the plurality of power suppliers includes: acquiring a plurality of electric power supply information including power supply requirements of a plurality of electric power suppliers; calling an intelligent contract to obtain a transaction matching algorithm; calculating the matching degree between the power demand party and the plurality of power supply parties according to the power demand information, the plurality of power supply information and the transaction matching algorithm; and determining a target power supplier corresponding to the power demand information from the plurality of power suppliers according to a matching degree between the power demand supplier and the plurality of power suppliers.
Specifically, the intelligent contract is stored with transaction matching algorithm in advance, wherein the transaction matching algorithm includes but is not limited to power flow calculation, Kron cut method and Newton method. Referring to fig. 2, in the process of performing transaction matching, the blockchain system 200 first obtains a plurality of pieces of power supply information including power supply requirements of a plurality of power suppliers, then calls an intelligent contract to obtain a transaction matching algorithm, and calculates a matching degree between the power supplier and the plurality of power suppliers according to the power demand information, the plurality of pieces of power supply information, and the transaction matching algorithm. In the process of calculating the matching degree, a power flow calculation method based on a sparse matrix is adopted, the power demand information and each piece of information in the plurality of pieces of power supply information are used as each element of the matrix, unnecessary nodes are cut off by a Kron cutting method, then a numerical solution of the matrix is obtained by a Newton method, and the matching degree between a power demand side and the plurality of power supply sides is determined according to the obtained numerical solution. Finally, the blockchain system 200 determines a target power supplier corresponding to the power demand information from the plurality of power suppliers according to the matching degree between the power demand supplier and the plurality of power suppliers. In this way, the target power supplier can be quickly matched for the power demand side, and therefore transaction matching can be quickly completed on the block chain.
Optionally, the operation of calculating the matching degree between the electricity demand side and the plurality of electricity suppliers according to the electricity demand information, the plurality of electricity supply information and the transaction matching algorithm includes: encrypting the power demand information, the plurality of power supply information and the transaction matching algorithm; sending the encrypted power demand information, the plurality of power supply information and the transaction matching algorithm to preset trusted computing equipment, and computing the matching degree between a power demand party and a plurality of power supply parties through the trusted computing equipment; and receiving, from the trusted computing device, the encrypted degrees of match between the power consumer and the plurality of power suppliers.
In order to further improve the efficiency of transaction matching on the blockchain, for the task whose computation is heavy in the transaction matching, the blockchain system 200 may move the task to be performed under the chain, and establish a trusted computing environment between the intelligent contract on the chain and the computing environment under the chain, so as to ensure the confidentiality and the credibility of the computing result by using the cryptographic public and private key method. Specifically, the blockchain system 200 encrypts the power demand information, the plurality of power supply information, and the transaction matching algorithm, and then sends the encrypted power demand information, the plurality of power supply information, and the transaction matching algorithm to a preset trusted computing device, and the trusted computing device calculates the matching degree between the power demand side and the plurality of power supply sides. And, after completing the computation, the trusted computing device encrypts the computation result and sends the encrypted computation result to blockchain gesture 200. The trusted computing device may be deployed on the server 300, or may be deployed on another server, which is not limited herein. By the method, the confidentiality and the credibility of the calculation result are guaranteed, and meanwhile the efficiency of transaction matching is further improved.
Optionally, the method further comprises: receiving, from a server deployed with a predictive engine, trade data relating to a trade order; and calling an intelligent contract, and judging whether the power demand side and the target power supply side execute corresponding transaction operation according to the transaction data.
Specifically, referring to fig. 2, in the transaction execution phase, transaction data (e.g., power internet of things (IoT) device data and trusted data source data) related to the transaction is collected by the server 300 with the prediction machine deployed, and the collected data is sent to the blockchain system 200.
