一种基于加权秩和比法的光伏并网逆变器多性能指标评价方法研究

Research on Multiple Performance Indexes of Grid-Connected Photovoltaic Inverters Based on a Weighted Rank-Sum Ratio Method

提出了一种采用加权秩和比法(WRSR)来评价光伏并网逆变器的多指标整体性能。采用方法对某光伏电站的10家企业10种不同型号光伏并网逆变器的6项主要性能指标进行了综合评价和比对,给出了分档排序,其结果数据为后续光伏电站建设中光伏并网逆变器的选择提供了重要参考依据,并可以为光伏并网逆变器产品质量的提升和改进提供数据支撑。

A weighted rank-sum ratio(WRSR)method was proposed to evaluate the overall performance of grid-connected photovoltaic inverters,and this method is used to comprehensively evaluate 10 companies of 10 different types of grid-connected photovoltaic inverters based on the six main performance indexes with the rank results.The result data provide an important reference for the choice of grid-connected photovoltaic inverters for the subsequent construction of photovoltaic power stations and can be the support for the promotion and improvement of the grid-connected photovoltaic inverters.
