Security Architecture Design of Virtual Power Plant Based on Edge Computing and Blockchain

Inhalt:
With the integration of large-scale renewable energy into the grid, the power grid has increasingly higher requirements for the scale of virtual power plant (VPP) that can aggregate user-side flexible resources. However, with the increasing number of distributed energy resources (DERs) connected, the heterogeneous data generated by the terminal also increases, which poses new challenges for VPP data management in terms of real-time, stability, and security. Aiming at the difficulties of the existing VPP architecture in processing massive edge data, based on the advantages of edge computing and blockchain in edge data processing and cloud information security management, this paper proposes a VPP security architecture design method. The application applicability of edge computing, blockchain, and VPP is analyzed, the edge computing nodes (ECNs) configuration and technical architecture are introduced, and the specific services that the architecture can be applied to are explained. The encryption and verification function of the command of the cloudside collaboration and contract information is designed. This architecture can better take into account the real-time information on the edge, which is conducive to the overall scheduling of the VPP and also improves its stability and safety.
