It is of great significance to the reasonable power system planning and guarantee the safe operation of the power system that determine the distribution network planning. This paper puts forward the evaluation index system of power distribution network planning considering micro grid access. Distribution network planning scheme for the calculation of index weight through the improved AHP method, and the final plan evaluation using the weighted sum method. Collecting multiple expert opinion and according to the different structure of the expert experience weighted average of the judgment matrix and improving the consistency check method is the AHP improved thoughts.Finally, through the case analysis, using the proposed evaluation method and comprehensive score of 4 kinds of planning. Grading result is the plan 1, 2, 3, 4 respectively scored 0.285, 0.196, 0.307, 0.212. The evaluation result and expert evaluation result are consistent, and this method was verified in the scientific nature and rationality of evaluation on power distribution network planning.
