The Research on Multi-Dimensional Evaluation Index System of Distribution Network Loss

At present, the evaluation of regional distribution network loss usually uses a single line loss rate index as the evaluation standard. Comprehensively considering factors such as the distribution grid structure, equipment status, power consumption structure and other factors, this paper establishes a multi-dimensional evaluation index system of the distribution network line loss from three aspects as line loss rate, power grid operation and planning, line and transformer equipment. Taking the line loss situation of the distribution network in two regions of a province as an example, the evaluation index system and corresponding evaluation method are used for evaluation. The calculation example shows that the constructed index system can comprehensively and effectively evaluate the overall situation and weak links of the regional distribution network line loss, thus guiding the direction of regional distribution network loss reduction.
