摘　　要：为研究分布式电源接入电力系统后的电压和无功优化问题,提出基于多代理系统(MAS)的一种电压无功优化协调控制新方法。以系统网损最小为目标,同时考虑电压稳定性,通过MAS构建以辅助问题原理进行分区分布式计算的电压无功优化协调控制模型,并通过分区并行求解获得全局最优解,得到最优网损和节点电压稳定数据;研究单个和多个分布式电源接入后,系统电压无功变化情况,通过分析得出分布式电源的最佳接入位置,即分布式电源从此点接入对系统电压无功的影响效果最好。最后,利用EPRI-36节点系统进行仿真计算,结果证明了所提方法的合理性与正确性。In order to quickly and efficiently solve the problem of voltage and reactive power optimization after the distributed generation is connected to the power system,a new method of voltage and reactive power optimization coordination control based on multi-agent system(MAS)is proposed.With the goal of minimizing the system loss and considering voltage stability,a partitioned distributed optimization and coordinated control model based on auxiliary problem principle is constructed by MAS.The global optimal solution is obtained after partition parallel solving,and the optimal system loss and node voltage stability data are obtained.The changes of system voltage and reactive power after single and multiple distributed generations accessing are studied.The optimal access position of distributed generations is obtained through analysis,that is,the access from this point has the best effect on the system voltage and reactive power.Finally,the rationality and correctness of the proposed method are proved by simulation calculation of the EPRI-36 node system.
