摘　　要：电能质量综合评估对电网实施有效治理和电力市场改革背景下供需双方进行交易价格的制定至关重要。为使电能质量的评估结果更接近实际,本文提出基于博弈论组合赋权的TOPSIS电能质量综合评估方法。首先根据建立的评价指标体系,采用三标法对传统AHP法进行改进,得到指标主观权重,再使用熵权法求取指标的客观权重;其次引入博弈论思想将主、客观权重进行线性组合,得到指标的最终权重;最后采用改进的TOPSIS算法进行电能质量的综合评估。通过算例验证了方法的可行性。The comprehensive evaluation of power quality is very important to the pricing of power supply and demand under the background of effective power grid governance and power market reform. In order to make the evaluation result of power quality more close to reality, this paper proposes TOPSIS comprehensive evaluation method of power quality based on combination weighting of game theory. First, according to the established evaluation index system, the traditional AHP method is improved by using the three-standard method to get the subjective weight of the index, and then the entropy weight method is used to get the objective weight of the index. Secondly, the game theory is introduced to combine the subjective and objective weights to get the final weight of the index. Finally, the improved TOPSIS algorithm is used to evaluate the power quality comprehensively. The feasibility of the method is verified by an example.
