满足电能质量限值的分布式光伏极限峰值容量计算
Limit Peak Capacity Calculation of Distributed Photovoltaic with Power Quality Constraints
摘要
Abstract
With the large number of distributed photovoltaics ( PVs) dispersedly accessed in middle‐low voltage distribution network , power quality problems of distribution network are becoming increasingly conspicuous , making the limit peak capacity of distributed PV accessed in distribution network the focus of attention . Following a study of the influence factors and the influence level of distributed PV on the power quality , an optimal calculation model based on the current injection method is proposed to meet the need of limits of power quality . The model is constrained by power quality indices of multiple national standards , with the peak value of the distributed generator accessed given for both new and expanded cases of limit peak capacity . The validity and practicability of the model are verified by the test results of the IEEE 33‐bus system and actual LCX system . For the features of typical 10 kV line , the safety limits of distributed PV with power quality constraints are given according to different line types in different regions . The results can provide reference for the power supply enterprise in checking the grid‐connected application of distributed PVs .关键词
