Abstract

Abstract: With the in-depth reform of the power industry, the reliability index evaluation system of the distribution network has become an important direction for the research of my country's distribution network. Firstly, the load points are classified based on the power supply information of the distribution network, and the power supply reliability indicators of the system and consumers are established. Secondly, a comprehensive evaluation system of distribution network indicators is established based on the entropy weight-analytic hierarchy process with maximum deviation. Finally, the comprehensive evaluation index results are used to establish a distribution network reliability incremental cost calculation model, and the distribution network reliability electricity price that takes into account the differentiated reliability requirements is obtained. The analysis of calculation examples shows that the proposed evaluation system can obtain comprehensive reliability evaluation indicators with subjective and objective evaluation. And the results can be applied to reliability electricity price calculation to obtain reliability electricity prices that take into account both reliability and economy.
