The invention discloses a decision and evaluation method for an intelligent power distribution network group based on fuzzy assessment. An evaluation index system of a recursion order hierarchy system of the intelligent power distribution network is established, experts evaluates indexes according to index positive and dimensionless results, subjective evaluation is combined with objective evaluation, combined evaluation is carried out by combining the expert weight and the index weight, and evaluation values of comprehensive effectiveness is given to different schemes. The decision and evaluation method is suitable for the condition that construction schemes of intelligent distribution network are compared, and the evaluation result can provide decision basis for programming, design, construction and operation management staff.
