Abstract:

A fully decentralized VPP（Virtual Power Plant） does not have a centralized organization and supports the free access of distributed energy. It is one of the mainstream modes of VPP in the future. Based on the consistency of VPP and blockchain in decentralization, point-to-point interaction and decentralized coordination, it is proposed to realize the distributed scheduling of VPP by using the blockchain consensus mechanism, combined with the equal consumed energy increase ratio law, the increase ratio feature is used as a consistency variable to achieve optimal economic dispatch of the VPP. Each distributed energy in the VPP acts as a node of the blockchain network and has a complete backup of the key data in the whole network. When the load changes, the PBFT consensus algorithm is used, and each node independently calculates the new power and the new power data is stored in blockchain, while maintaining the global consistency of the increase ratio features to achieve a reasonable distribution of load between the distributed energy. The effectiveness of the algorithm is verified by simulation experiments, distributed scheduling is realized by blockchain, which provides a feasible reference scheme for the operation mode of distributed VPP.
