Fixed-time Distributed Economic Dispatch Based on Event-triggered Strategy

Abstract

For the smart grid, it is highly significant to achieve the fixed-time economic dispatch so as to optimize better the cost of power generation. It can effectively save the communication resources by taking advantage of the event-triggered scheme. In this paper, a fixed-time economic dispatch algorithm based on event-triggered strategy is presented to solve the problem of limited communication resources in power system and find the optimal power generation in a finite interval. The convergence analysis of the algorithm and the proof of avoiding Zeno behavior are exhibited in details, respectively. Finally, the feasibility and advantage of the optimization algorithm are verified by numerical simulation for economic dispatch of grid six generators.
