Comprehensive Evaluation of Power Quality for Microgrid Based on CRITIC Method

Abstract

Due to the existence of power electronic equipment and uncertain load in the power generation side and the user side, power quality has gotten a great deal of attention. How to reasonably evaluate various power quality indicators is one of the problems in microgrid power management. A method based on CRITIC (Criteria Importance Though Intercriteria Correlation) is proposed which is applied to power quality assessment in this paper. By determining the weight of each index, the method effectively identifies the power quality problems and accurately evaluates the severity of various power quality problems.
