Evaluation Method of Initial Planning and Design of Distribution Network Based on Improved Analytic Hierarchy Process
The accuracy of the evaluation result of initial planning and design of distribution network is easily affected by the calculation re-sult of index weight.An evaluation method of initial planning design of distribution network based on improved analytic Hierar-chy process(AHP)is studied.By calculating the cumulative contribution rate,more than 85%of the evaluation indicators are se-lected to form a three-tier index system.The equilibrium factor is introduced to improve the index weight of analytic hierarchy process.Combined with the index weight,the weighted rank sum ratio method is used to calculate the probability unit value,namely,the initial planning effect score of the distribution network.According to grade division standard,it determines the initial planning effect grade of distribution network.The results show that the effect of scheme 1 and Scheme 4 reaches excellent level,the design is the most reasonable and can be adopted.
