Research on Establishment and Method of Performance Evaluation Index System of smart grid Distribution Network

It is an important requirement for the operators to control the power grid to evaluate the operation performance of the smart power distribution network reasonably and accurately. This paper from the perspective of the smart grid efficiency, effect and benefit, build up a set of evaluation index of the performance of the smart grid distribution network state system. First, through the expert method, experts from the perspective of three index system screen the center index and the non-central index, next using the improved fuzzy clustering method to correct the center index and the non-central index again, and then using the analytic hierarchy process (AHP) to improve the group gray correlation method to correct the rest of the center again and eliminate redundant indicators. The mixed weight obtained by analytic hierarchy process and entropy weight method is used to evaluate the final determined evaluation system. Finally, an example of a regional power grid is used to verify that the evaluation system and method proposed in this paper can easily and accurately reflect the smart power grid efficiency status.
