The article investigates the optimal energy management (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 dependence on the initial states。 The dynamic ET method is raised to dynamically adjust the triggering threshold and reduce communication redundancy。 In addition， Zeno behavior is avoided。 Simulations are given to show the effectiveness and advantage of the designed distributed OEM method。
