A comprehensive evaluation method for the security situation of distributed power supply in distribution network

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