Planning is vital for the development of power system; and the quality of planning has direct influence on security, reliability and economy of the power system in the future. Therefore, it is urgently needed to study quantitative evaluation method for distribution network planning. First, this paper proposes a practical comprehensive hierarchy and method on evaluation of distribution network planning. Second, the implementation steps for the evaluation of planning network are given, which include the determination of indices hierarchy and the evaluation of planning. In the end, this paper takes 10 kV network distribution planning of a district in China for example in order to illustrate the specific evaluation steps and methods based on the hierarchy, at the same time, the case shows that the evaluation method has strong feasibility and practicability. The planning evaluation hierarchy and method proposed in this paper can not only seize the key elements influencing the characteristics of network planning, but also describe the planning integrally and quantitatively, and possess significant engineering practicability.
