A Novel Blockchain-Based Distributed Power System Control Design

Abstract

The large-scale penetration of distributed power systems in the power grid makes the safe and stable operation of the power grid a difficult problem. The distributed control strategy is more suitable for distributed power management than centralized control. However, distributed control that relies on network communication is vulnerable to network attacks, so research on security control strategies is very urgent. Blockchain technology is widely used in the field of energy trading due to its special security mechanism, distributed ledger, and decentralization. It is difficult to develop in the control field due to performance and latency issues. In this paper, we propose a blockchain-based distributed control architecture for island microgrids. Through ingenious structural design, the communication security of the blockchain is fully utilized, and troublesome on-chain calculations are avoided. Simulation results demonstrate the superiority of this architecture.
