This paper researches the different configuration modes of distributed generation, such as installation location, installation capacity and influence on distribution network, analyzes the running power factor, energy loss, network topology, voltage control mode with traditional voltage control equipment, and gives relevant conclusions, so that power system planning, dispatching and running engineer can process in time, effectively guide customers to connect distributed power to distribution power grid, minimize the distributed power impact to distribution power system. As for the access point and capacity optimization of distributed generation in distribution network, this paper proposes the intelligent optimization algorithm to solve the optimal access mode of distributed power supply. The objective is to maximize the capacity of distributed generation and minimize the system energy loss. At the same time, the upper and lower limits of branch current carrying capacity, main transformer capacity, section active power and node voltage are taken as constraints. By the calculation and analysis of the access capability of a real distribution network, the effectiveness of the proposed method is verified.
