Establishment of Smart Distribution Grid Evaluation System

Abstract

This paper analyzes the core values of the smart grid that is the need of significant stakeholders, the reliable and efficient electricity supply for users and running economy for power grid enterprises. Using fishbone analysis gets the main elements, which are the quality and reliability of power supply, grid structure, equipments situation, intelligence level and operation level. Due to the complexity of the evaluation system,the entire system divided into three layer levels,the target layer, the element layer and the index layer. The structure and operation of low voltage distribution grid and medium-high voltage distribution are significantly different,they separate into two systems to evaluate,it can get the evaluation index system. Compared with the traditional distribution grid evaluation system, this system is more comprehensive and systematic for evaluation the development level of the smart distribution grid,it is practically valuable for evaluation work.
