Abstract: In the paper, the comprehensive evaluation index system of distribution grid is established with renewable energy on the basis of comprehensive evaluation on traditional distribution grid. This index system can make evaluation on distribution grid more comprehensively from equipment operational condition, power distribution reliability, power quality, economical efficiency and environmental protection property, highlighting the characteristics of distribution grid with renewable energy different from the traditional distribution network. The comprehensive evaluation method based on extensional analytic hierarchy process is also put forward. Considering vagueness in human judgment based on traditional analytic hierarchy process, this method is easier to meet the requirement for consistency in judgment matrix. At last, the comprehensiveness of index system and adaptability of evaluation method are verified through analysis of examples.
