Distributed Event-based Algorithm for Economic Dispatch Problem over Digraph with Time delays
Zhongyuan Zhao, Gang Chen · 2018
The economic dispatch problem(EDP) in microgrid over directed networks with communication time delays is investigated. We design a distributed event-based algorithm to handle EDP in microgrid over strongly connected and balanced digraph. Furthermore, the effect of time delays has been considered. By graph theory and Lyapunov method, an appropriate event-triggered condition is obtained and the corresponding sufficient condition which guarantees stability of the proposed algorithm is devised. As the periodic sample control has been adopted, the Zeno behavior is excluded naturally. Finally, Simulation results demonstrate the effectiveness of the algorithm.
