摘要
多微网系统由多个子微网构成,其控制策略较单微网系统更为复杂。针对并联结构的多微网系统,提出了一种基于预测控制的多微网协调控制策略,通过预测控制求得多微网协调因子的最优值,基于此最优值协调各微网之间的功率分配,从而维持整个微网电压和频率的稳定。仿真结果表明,该控制策略能够有效地应对微网之间的功率波动。
A multi-microgrid system consists of several microgrid systems,requiring more complex control strategy than a single microgrid system. Based on predictive control,this paper presents a coordination control strategy for parallel-type multi-microgrid systems. The optimal value of coordination factor is sought through predictive control,then with the optimal value the power distribution among the multi-microgrid system is coordinated for maintaining the stability of voltage and frequency. Simulations demonstrate that the proposed control strategy can achieve good control effect in dealing with power fluctuation among microgrids.
