Research on differential loss benchmark of power loss management in power supply enterprise

Abstract

Power loss is an important index to evaluate the benefit of the power enterprise. In this paper, a modified power loss benchmark is proposed to calculate the reasonable power loss in the distribution system. First of all, based on grid divider structure, establish the power facility configuration model according to the distribution network load density. Then, on the basis of the power facility configuration model, establish the economic cost model of power supply, optimization economic power supply radius, making the grid annual operation of the minimum cost. Moreover, calculate the reasonable power loss benchmark. Finally, consider the access of distribution generator, according to the effect of distribution generator on the power distribution, and re-formulate the benchmark. The results of this paper can be utilized to evaluate the power loss status and make the power loss reduction plan for the power enterprise.
