Study on Distribution Network Comprehensive Optimization Method Including Distributed Power Supply

This paper discussed the influence of distributed power supplies with different locations and volumes on distribution network after combination, and studies the reactive power optimization of distribution network including distributed power supply. The improved genetic algorithm was adopted with the maximum comprehensive economic benefits as the objective function, the address selection volume setting of the distributed power supply in the distribution network and the capacitor switching are combined for comprehensive optimization. The example analysis result showed that the method can realize distributed power supply optimal configuration and distribution network reactive optimization in the distribution network at the same time, thereby effectively lowering the distribution system loss, improving the voltage quality, and better comprehensive economic benefits can be obtained.
