Abstract

For enhancing the accuracy and rationality of power quality (PQ) evaluation, close value method (CVM) based on the target optimization principle is introduced to symbolize the performance of PQ samples. To tackle with the defect, in calculating close value of PQ samples, that the calculation formula of close value is divided by zero, a modified CVM is correspondingly developed to adapt to the randomness of PQ samples. Meanwhile, for analyzing the impacts of weighting approaches on the evaluation outcome, different weighting approaches are orderly utilized to improve CVM. Case analysis shows that the new calculating method of close value is proved to be more simplified and applicable; the impacts different weighting approaches have on the evaluation outcome differ to some extent.
