Embodiment Construction

[0043] Such as figure 1 and figure 2 As shown, this embodiment provides a distribution network demand response transaction settlement method based on blockchain technology, including:

[0044] (1) Data preparation: generator wallet address, user wallet address, transaction period between user and generator, transaction settlement period between user and generator, user’s historical load data, and user’s response should be accepted when the user’s response is less than the specified value of the contract. The penalty amount coefficient.

[0045] (2) Deploy the first smart contract that calculates the total demand response volume: in each trading period, the power generation provider in the distribution network issues a purchase request for demand response resources, and sends the first smart contract to deploy the first smart contract according to the historical price of demand response resources. The multi-signature public address is transferred to a preset amount of virtua...

Abstract

The invention discloses a distribution network demand response transaction settlement method based on block chain technology, which comprises the following steps: (1) performing data preparation: participant addresses, contract periods, user load values, etc. (2) constructing an intelligent contract to calculate the total resource demand, recording demands of all power generators, and calculatingand publishing a total demand; (3) constructing a contract to calculate the supply of each user, and adjusting the price according to the supply of each user to meet the total demand of the power generators; and (4) constructing transaction settlement contracts between the users and the power generators, and completing the token transfer according to capacities of the users and quoted prices. Theinvention designs a demand side response transaction mechanism based on block chain technology in distribution network, the power generators send resource demands for the next transaction period to apublic account, the users monitor the demands and the quoted prices published on the block chain to update the supply, and the public account updates the quoted prices until the demands are satisfied,thus realizing the optimal dispatching of distributed energy sources.

Description

technical field [0001] The invention relates to electric power technology, in particular to a transaction settlement method for distribution network demand response based on block chain technology. Background technique [0002] With the development of the electricity marketization process and the implementation of demand response projects, electricity consumers gradually participate in market competition and form multilateral transactions, which makes electricity transactions more free and more complicated. The difficulty of managing transactions has also increased significantly. [0003] In the modern distribution network, consumers are gradually transforming into prosumers. At the same time, considering that the distribution network has the characteristics of a large number of users and high privacy requirements, it is necessary to focus on how to establish an efficient and safe transaction model. At this stage, the management of transactions is mainly divided into two ty...
