Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0035] Due to the randomness and volatility of distributed power sources, and the introduction of a large number of prosumers in the transaction process, traditional centralized transactions need to spend huge costs to establish trust among different users, and at the same time, transaction data is collected by centralized institutions. There is also the security issue of transaction data. With its characteristics of decentralization and non-tamperable data, block chain technology can break trust barriers and realize safe and efficient P2P (Point to Point) energy transactions; To increase the enthusiasm of users; based on smart contract technology, the transaction process of distributed power supply is automatically executed, and the transaction data is written into the Merkle tree in real ti...

Abstract

According to the distributed power supply end-to-end transaction method and system based on the smart contract, the structure is simple, the design is reasonable, accuracy and convenience are achieved, the characteristic requirements of randomness and volatility of the distributed power supply can be met, and the transaction flexibility and safety are guaranteed. The method comprises the following steps: collecting end-to-end transaction information of a distributed power supply through a P2P energy transaction network; obtaining distributed power supply transaction demand data according to a supply-demand relationship in the transaction information; through at least one of a preset load verification smart contract and an economy constraint smart contract, verifying the security or economy of a corresponding power grid load on the distributed power supply transaction demand data to obtain verified power supply transaction demand data; according to the verified power transaction demand data, carrying out market settlement and value transfer of the power transaction through a preset transaction settlement smart contract to obtain power transaction data, and recording the power transaction data in the block chain.

Description

technical field [0001] The invention relates to the field of distributed power supply transactions, in particular to a distributed power supply end-to-end transaction method and system based on smart contracts. Background technique [0002] With the continuous development of the power system, more and more distributed power sources such as electric vehicles, photovoltaics, and wind power have been put into the power system. The large-scale use of electric vehicles will lead to an increase in the peak load of the urban power grid by about 10% to 11%. In extreme cases, this increase may cause gaps in the installed power capacity and transmission line capacity in some areas. Therefore, how to make distributed power generation reasonably connected to the Internet and participate in distribution network transactions is an urgent problem to be solved. [0003] Distributed power generation has the characteristics of randomness and volatility, and is easily affected by the environm...
