Abstract

As the large-scale integration of photovoltaic(PV) power station, a higher requirement is put forward by power grid analysis on the accuracy of PV station model. The PV station applies different strategies with/without scheduling instructions, or under normal/failure condition, so it has different characteristics in multi-time scale. In order to study its dynamic characteristics, an active power control model of PV power station suitable for full dynamic simulation was proposed, which could simulate the active power fluctuations of PV power station using light intensity/temperature and schedule command curves, by building station AGC control model and inverter control model. The proposed model was realized in PSD-FDS program and verified using measured data from Ningxia grid. The simulation results show that the proposed PV power station model could provide effective tool for analyzing the PV power station's dynamic characteristic.

适合全动态仿真的光伏电站有功功率控制模型

随着光伏电站的大规模集成化，电网分析对光伏电站模型的精度提出了更高的要求。光伏电站在有/无调度指令、正常/故障情况下采用不同的调度策略，因此在多时间尺度下具有不同的特点。为了研究其动态特性，提出了一种适合全动态仿真的光伏电站有功功率控制模型，通过建立电站AGC控制模型和逆变器控制模型，利用光强/温度和调度指令曲线模拟光伏电站有功功率波动。在PSD-FDS程序中实现了该模型，并用宁夏电网实测数据进行了验证。仿真结果表明，该模型可以为分析光伏电站的动态特性提供有效的工具。
