Distributed Economic Dispatch for Cyber Attacked Smart Grid Based on Resilient Event-Triggered Consensus

This paper mainly studied the distributed economic dispatch optimization problem of power system which takes the security of communication network into consideration. Firstly, a new single area power system economic dispatch model is given which takes the environmental pollution penalty into account. An optimization approach based on gradient descent and multi-agent consensus protocol is proposed to solve the generation cost minimization problem. A novel distributed resilient event-triggered scheme is proposed to ensure the stability and economy of power system under denial of service (DoS) attack. Then the prerequisites to minimize the system power generation cost are analyzed from the aspects of optimality and economy. Finally, the effectiveness of the proposed method is verified by simulation experiments.
