Currently, benchmark value setting of theoretical line loss rate for medium voltage (MV) feeders mainly depends on historical value, management experience or other factors, lacking theoretical basis. Thus, this paper proposes an optimal design method of benchmark value, based on fuzzy clustering and correction algorithmof ground state line. Firstly, from aspect of line loss contribution rate and data acquisition, a three-dimensional index system for feeders in MV distribution network is established. Secondly, fuzzy clustering with validity on the feedersis carried out and ground state feeder chosen. With help of equivalent resistance method and statistical method, theoretical line loss rate is calculated. Finally, optimal model of theoretical line loss rate benchmark value is established to obtain benchmark value. This model sets goal of making the largest feeder loss reduction space. Its constraints areoperation management level, equipment frame condition and probability distribution of theoretical line loss rate of feeders. Analysisof an example, containingfeeders from a city power supply enterprise in Guangdong Province, verifiedits scientific validity and universal applicability of theproposed method.
