In order to study the influence of distributed power access on the security state of distribution network, a comprehensive evaluation method for the security state of distribution network including distributed power access was proposed.Based on the output model and load model of photovoltaic power supply, the security situation assessment index system of distributed power supply access distribution network is established. Then combined with fuzzy analytic hierarchy process and entropy weight method, the composite weight of each index is obtained, and the combined weight is optimized based on chi-square distance. Finally, the evaluation method based on ER algorithm (Evidential Reasoning) is proposed. Simulation results verify the effectiveness and accuracy of the proposed method.
