Optimal Control of Active Load Interconnected System in DC Microgrid via an Adaptive Decentralized Event-Triggered Mechanism

In this brief, an innovative adaptive event-triggered control approach is devised to solve the optimal control problems of power buffer systems in DC microgrids. The optimal control problem of power buffers is addressed via a decentralized framework to ensure mutual interconnection among subsystems. Additionally, the adaptive dynamic programming (ADP) method is integrated with an event-triggered mechanism to derive an approximate optimal control strategy, which can effectively reduce the communication overhead between different subsystems. Moreover, the stability of the interconnected system is proved and the Zeno behavior is rigorously excluded through theoretical analysis. The effectiveness of the proposed method is validated through a DC microgrid case study.
