Study on Grid-connected Operation Performances Evaluation of Photovoltaic Power Stations

Abstract

To achieve the grid-connected operation performances evaluation of photovoltaic power stations, a grid-connected operation performance index system and the comprehensive evaluation method on photovoltaic power station grid-connected performances is presented. The rank sum ratio of each photovoltaic power station to reflect grid-connected performances is calculated by using the rank-sum ratio method. According to the rank sum ratio values, the comprehensive grid-connected performance of each photovoltaic power station is evaluated. The actual monitoring data of photovoltaic power stations are used to calculate performance indexes, and comprehensive evaluation on grid-connected performances of photovoltaic power station is verified. The obtained results show that the comprehensive grid-connected performance of the photovoltaic power station can be correctly evaluated by using the presented evaluation method.
