摘要
微网系统经济调度是目前微网研究的热点问题。针对该问题,提出了一种基于多智能体系统的孤立微网功率经济分配方法。该方法结合下垂控制与多智能体一致性理论,通过下垂控制实现电网功率平衡,并使用基于一致性理论的功率控制器协调控制各个电源出力,最终达到微网功率经济分配。该方法能够实现实时完全分布式控制,该控制基于点对点通信,无需中央控制器进行协调。同时该方法利用下垂控制信息,无需负载与新能源功率信息,减少了通信系统规模,提高了系统可靠性。分析了系统的动态模型与收敛性,给出了系统参数设计方法。算例结果验证了所提算法的有效性。
Economical dispatch problem is an active research field in microgrid. In this paper, a multi-agent based algorithm for economical power dispatch for rrfierogrid is presented. This algorithm combines droop control maintaining power balance in microgdd and a consensus algorithm based economy regulator tuning output power of each generator to reach optimal power dispatch for microgrid. This algorithm can realize fully distributed control without central coordinator. In addition, with help of droop control, communication only happens between traditional generators, thus greatly reducing communication nodes in the system. Dynamic model and convergence of the system was analyzed, and a parameter design guideline is given based on the model. Effectiveness of the control is validated with case study results.
