Abstract：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.
