Distributed Fixed-Time Optimal Energy Management for Microgrids Based on a Dynamic Event-Triggered Mechanism
The article investigates the optimal energy manage-ment(OEM)problem for microgrids.To figure out the problem in fixed time and alleviate communication load with limited resources,this article devises a novel fixed-time stability lemma and an event-triggered(ET)fixed-time distributed OEM approach.Using Lyapunov stability theory,the distributed approach has been proven to converge in fixed time and the upper bound on convergence time can be derived without depen-dence on the initial states.The dynamic ET method is raised to dynamically adjust the triggering threshold and reduce commu-nication redundancy.In addition,Zeno behavior is avoided.Sim-ulations are given to show the effectiveness and advantage of the designed distributed OEM method.
