Distributed Power Sharing Control Strategy for Interconnected AC and DC Microgrids Based on Event-Triggered Control Under Denial-of-Service Attack

Although the problem of power sharing in interconnected AC and DC microgrids formed through interlinking converters (ICs) has been extensively studied, the problem of active power sharing under the extreme conditions of three-phase imbalance/nonlinear loads and Denial-of-Service (DoS) attack has not yet been resolved. Based on this, this paper proposes an event-triggered distributed consensus control method to achieve active power sharing under such extreme conditions. Firstly, aiming at the active power sharing problem in interconnected microgrids under DoS attack, this paper proposes a distributed power sharing control strategy based on event-triggered control under DoS attack. Each IC is defined as an agent, and its first-order agent dynamics are constructed. Secondly, a stability criterion and proof of asymptotic stability considering DoS attack are provided. Finally, simulation and experimental results verify the effectiveness of the proposed method.
