On the basis of current research on energy saving indices of distribution network, according to relevant standards and rules, and considering its feasibility when used in reality, a set of index system for evaluating energy efficiency of distribution network is established. The proposed index system employs indices concerning distribution network planning, equipment parameters, and equipment operating status. The weight of index obtained by analytic hierarchy process and state value of index can be used to calculate comprehensive efficiency score of distribution network, in order to find the link of low energy efficiency in distribution network. The established index system is beneficial to explore energy saving potentiality, and to optimize capital investment for energy saving projects, and energy efficiency level of distribution network can be eventually promoted. The index system is applied to the distribution network of one provincial power corporation, and the evaluation result is in accordance with actual energy efficiency of evaluated distribution network, which verified the effectiveness and practicability of the established index system.
