Research on flexible resource access strategy based on block chain technology

In order to solve the problems of controllable load scheduling in the context of the development of distributed power trading mechanism, a decentralized transaction mode between controllable load users and load agents based on block chain technology was proposed. By integrating the operation characteristics of controllable load users and fully considering the purchasing and selling electricity demand information between different subclasses of users and load agents, two types of decision model functions of controllable load users and load agents are designed. Based on the basic principle of income optimization, a block chain node model is established considering operation and maintenance cost and operation efficiency. Based on the controllable load user-load agent blockchain transaction mode, the profit sharing incentive mechanism and the intelligent contract solving algorithm of the load agent are designed. At the same time, the change rate of the efficiency function of the load agent is proposed as the consensus algorithm, and the structure and operation process of the blockchain data are explained. The results of example analysis show that the proposed optimal scheduling strategy fully taps the potential of controllable load users and load agents for peak load cutting and valley filling of power grid, achieves economic optimization for both parties and guarantees the long-term effective operation of blockchain network, which can provide reference value for the application of blockchain technology in power demand response.
