Modeling and Simulation of Photovoltaic Grid-Connected System Based on PSASP/UD

在研究光伏并网系统的主要技术指标、控制策略、输出特性的基础上,利用电力系统分析综合程序PSASP/UD,开发、添加了适用于复杂网络环境下的系统模型,使模型具备光伏并网仿真的能力。将模型接入系统CEPRI-36算例,进行潮流稳态计算和短路暂态仿真。算例仿真证明了该模型能够准确地模拟光伏并网系统的输出特性,验证了理论方法的正确性。

Based on the study of photovoltaic （PV） grid-connected system＇s main technical index, control strategy and output characteristic, the power system analysis software package PSASP/UD was used to develop and add a system model adapting to complex network environment, which has the ability of PV grid-connected power system simulation. Through the simulation example, it proves that the model can accurately simulate the output characteristics of photovohaic grid-connected system, and the theoretical method is correct.
