In the traditional distribution network reconfiguration method with distributed generation, distributed generation is equivalent to a constant power factor output model, which does not take into account the influence of node voltage variation on reactive power output of distributed generation. This paper put forward a method of distribution network reconfiguration with distributed generation considering the different output characteristics of distributed generation. First, distributed generation is classified and an equivalent model is established. The model fully considers the influence of node voltage on reactive power output of distributed generation, and it can identify reactive power output of distributed generation based on node voltage. Then the adaptive fireworks algorithm is used to optimize the distribution network reconfiguration, and the network loss and the node voltage of the reconstructed system are compared and analyzed. The simulation results of a typical IEEE 33 node test system with distributed generation verified the validity and authenticity of the proposed model.
