    摘 要:层次分析法(AHP)是电能质量评估的一种常用方法,但易受到主观意志的干扰。研究了一种将层次分析法与熵权法结合形成主客观结合的电能质量评估方法,通过引入熵权法将各指标的实际波动情况引入权重计算中,以此减小主观因素对权重分配的干扰。介绍了电能质量的综合评估流程,对电能各指标权重系数的计算进行了阐述,仿真实验表明该种方法得出的电能质量更加符合实际情况。

    Abstract: The analytic hierarchy process (AHP) is a commonly used method for the power quality assessment, but it is easily disturbed by subjective will. This paper researched on a kind of power quality assessment method combined the AHP with the entropy weight method including subjective and objective elements. The entropy weight method was used to make the actual fluctuation of each index introduced to the weight calculation, so as to reduce the interference of small subjective factors on the weight distribution. Introduction was made to the comprehensive assessment process of power quality and expounded each index weight coefficient calculation. The simulation results show that the power quality obtained by this method is more in line with the actual situation.
    Key words: photovoltaic; power quality; comprehensive evaluation; analytic hierarchy process; entropy weight method
