Abstract

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.

基于动态事件触发机制的微电网分布式固定时间优化能源管理

文章研究了微电网的最优能源管理（OEM）问题。为了在固定时间内解决该问题，并在资源有限的情况下减轻通信负荷，本文设计了一个新颖的固定时间稳定性 Lemma 和一种事件触发（ET）固定时间分布式 OEM 方法。利用 Lyapunov 稳定性理论，证明了分布式方法可在固定时间内收敛，并可推导出收敛时间的上界，而不依赖于初始状态。动态 ET 方法可动态调整触发阈值，减少通信冗余。此外，还避免了 Zeno 行为。仿真显示了所设计的分布式 OEM 方法的有效性和优势。
