Comprehensive Evaluation Method

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.

Subjective Weight

The plan for power supply and distribution system in the Chemical Industry Park is complex. The evaluation method must be easy and truly show the site conditions in order to maintain the proper function of the system. Thus the fuzzy comprehensive evaluation method was chosen and applied in this paper. As for the weight calculation, Analytic hierarchy process (AHP) was used to compute the subjective weight; on the purpose of avoiding strong effect of subjective factors, the standard deviation for each index was calculated, and then the subjective weight was integrated to build the subjective and objective comprehensive weight model. Lastly fuzzy comprehensive evaluation method was applied into the model for assessing the power supply and distribution system in the Chemical Industry Park.
