摘要(Abstract)：

随着光伏电站大规模接入电网,电网仿真分析对光伏电站模型准确性提出了更高的要求。光伏电站在有/无调度指令、正常/故障工况下采取不同的有功控制策略,表现出多时间尺度的动态特性。为了研究其动态特性,提出了一种适用于全过程动态仿真的光伏电站有功控制模型。该模型以光照强度/温度的持续波动、调度总站的限功率指令作为输入,通过站级AGC控制模型和逆变器控制模型实现对光伏电站有功功率特性的仿真。该模型在大型电力系统分析软件包的全过程仿真程序(PSD-FDS)中得到了实现,并利用宁夏电网实测数据对光伏电站在不同系统工况下的特性进行了模拟。仿真算例表明,该模型可为光伏电站的并网动态特性研究提供有效的仿真手段。软件包的全过程仿真程序(PSD-FDS)中得到了实现,并利用宁夏电网实测数据对光伏电站在不同系统工况下的特性进行了模拟。仿真算例表明,该模型可为光伏电站的并网动态特性研究提供有效的仿真手段。
