摘要

With distributed generation access to the grid, power quality problems become increasingly prominent. These problems can threaten the safe and stable operation of the power grid. This paper establishes a distributed power quality comprehensive evaluation system. The improved entropy method is used to weight the subjective evaluation value and the objective evaluation value, to perform comprehensive evaluation of the power quality of the distributed distribution network. The subjective evaluation is obtained by the improved analytic hierarchy process, and the objective evaluation value is obtained by efficiency evaluation of the distributed power quality data by super efficiency data envelopment analysis. The results show that the improved entropy method considers both subjective and objective factors, resulting in comprehensive evaluation results that are more comprehensive and objective.
