Peer-Peer Electricity Transaction and Integrated Regulation of VPP Based on Blockchain

Virtual Power Plant (VPP) can offer flexible control and management of distributed power sources, energy storage system and dispatchable loads for grid supporting and economic operation. Peer-Peer electricity transaction and the integration of distributed power sources to participate in grid regulation such as frequency regulation and power reserve are two important functions for VPP. However, traditional centralized electricity transaction system is not competent due to its high trust cost, poor cyber and data security, and low execution efficiency. In this paper, an electricity transaction and regulation platform of VPP based on blockchain is proposed and designed. The platform is based on B/S structure with two typical scenarios proposed: the first one is VPP matching the internal users to facilitate the peer-peer mid-to-long-term electricity transaction, and the second is VPP integrating the different sources to participate in power system reserve services. The operability of the blockchain based management platform is verified in the above two scenarios respectively.
