To obtain a more objective and scientific result of power quality (PQ) fuzzy synthetic evaluation, this paper presents a combined weighing method to determine weights of PQ indices. The new method integrates advantages of both objective weighing and subjective weighing and remedies the defects of single-weighing. For more applications, a sequence synthesis-G1 technique is also put forward to evaluate PQ levels of the point of common coupling (PCC). Calculated results show that the proposed method with more ...
