| 摘 要： | 大型集中式并网光伏电站对区域电网稳态性能具有不可忽视的影响,该文研究了光伏并网发电系统的稳态模型和潮流分析方法。系统稳态模型基于电力电子变换原理和功率平衡原理建立,并考虑了最大功率跟踪(M PPT)控制策略。通过模型与光伏电站实测数据的对比,验证了模型准确性。利用该模型与电网潮流计算方法的交互,可评估光伏电站和电网在稳态性能方面的相互影响。在IEEE 30测试系统上分析了并网光伏电站的极限安装容量及对电网稳态性能的影响,结果表明现场太阳辐射条件是制约并网光伏电站极限容量的一个重要因素,大型集中式并网光伏电站对电网损耗和电压分布等稳态性能带来不同程度的影响。

| Abstract: | The impact of large-scale centralized photovoltaic(PV) power stations on the steady performance of regional power grids can not be ignored.This paper presents both a steady-state model and a power flow analysis of grid-connected(GC) PV generation systems(GS).The steady-state model is based on power electronic transforms and an instantaneous power balance,in conjunction with a maximum power point tracking strategy.The model accuracy was verified by comparison with measured data from an actual system.The mode... |
