Embodiment Construction

[0086] This embodiment provides a method for optimal scheduling of distributed power resources in a blockchain environment, such as figure 1 shown, including:

[0087] (1) Deploy renewable energy calculation contract A, contribution adjustment smart contract B, contribution collaboration smart contract C, and transaction settlement smart contract D on the blockchain.

[0088] Among them, such as figure 2 As shown, the renewable energy calculation contract A and the output coordination smart contract C are deployed on the public chain, the output adjustment smart contract B is deployed on the private chain or sub-chain, and the transaction settlement smart contract D is deployed on the main chain Above; participants in the same blockchain communicate with each other through state channels. After the transaction is completed, all transaction messages are packaged into blocks by the block generator in the blockchain, verified by the verifier, and stored on the main chain.

Abstract

The invention discloses a distributed power resource optimization scheduling method in a blockchain environment. The method comprises the steps that (1) a renewable energy calculation contract A, an output adjustment intelligent contract B, an output cooperation intelligent contract C and a transaction settlement intelligent contract D are deployed on a blockchain; (3) the contract A accumulates the total predicted power generation capacity of a renewable energy power generator and transmits the total predicted power generation capacity to the contract B; (4) the contract C generates a corresponding output adjustment signal according to the received auxiliary variable and transmits the output adjustment signal to the corresponding contract B; (5) the contract B adjusts the power price andthe power generation capacity of the power generator according to the received output adjustment signal, and judges whether the power price converges or not: the power generation capacity and the power price are transmitted to the contract D if the power price converges; otherwise, the power price is taken as an auxiliary variable for broadcasting; and (6) the contract D generates a transaction settlement contract according to the received power generation amount and price. According to the invention, the scheduling result is better, and the energy utilization rate is higher.

Description

technical field [0001] The present invention relates to electric power technology, in particular to a method and system for optimal dispatching of distributed power resources in a blockchain environment. Background technique [0002] With the promotion of Distributed Renewable Energy (DRE) and Demand Response (DR) technologies, the boundaries between generators and users in the distribution network are gradually blurring. The sheer number of these generators makes scheduling more difficult. The seasonal and intermittent nature of DRE makes it difficult to guarantee reliable supply, and even if non-renewable energy-driven generators can be used to meet user demand, it is difficult to determine dispatching strategies in a timely manner. [0003] DRE power generation resources have the characteristics of small capacity, large quantity, and wide distribution, which means that the centralized dispatching method faces problems such as high operating costs and long time consumptio...
