Multi-VPP multicentralized collaborative co-governance model based on DPoS consensus mechanism

Abstract

Virtual Power Plant (VPP), as a technology for the aggregated management of distributed resources, has received extensive research and application. Concurrently, as the process of power market reform advances, the collaborative operation of multiple VPPs has become a crucial research focus. Against this backdrop, this paper proposes a decentralized collaborative governance model for multiple virtual power plants based on the blockchain Delegated Proof of Stake (DPoS) consensus mechanism. Considering the dual characteristics of source and load in VPPs, a singular VPP scheduling model is introduced. The paper outlines the process of the blockchain DPoS consensus mechanism and introduces a decentralized iterative pricing mechanism for multiple virtual power plant systems. This mechanism, combined with the DPoS consensus mechanism, utilizes witness nodes as multi-centralized entities to safeguard against malicious attacks and single-point failures. Finally, case studies validate the effectiveness and rationality of the proposed model.
