The Loss Optimization for the Active Distribution System Considering the Renewable Distributed Generation

Due to the penetration of the renewable distributed generation, the operating mode and economy of the distribution system is being influencing and changing. Reducing power loss of the distribution system is the important operation requirements. On account of such reason, this paper proposes one power loss optimization model and solution process by sensitivity analysis (SA) algorithm, on the basis of the traditional optimal power flow (OPF) model. The model and solution process is simulated on the 34 node distribution system in North China, and the effectiveness of the algorithm is verified. Within a certain error range, SA algorithm has higher computational efficiency than the traditional OPF optimization process, and it would improve the operation of the active distributed system in practice.
