摘要

本文讨论了利用实时数字模拟器对并网光伏系统进行建模和仿真的方法。讨论了用解析迭代法对光伏阵列参数进行数学建模和推导的方法。采用最大功率点跟踪的正弦脉宽调制电压源变换器将PV阵列连接到三相电网。采用一种解耦的dq电流控制策略来控制光伏系统与电网之间交换的实功率和无功功率。对光伏发电系统的实时运行进行了分析。

Modeling and simulation of a grid-integrated photovoltaic system using a real-time digital simulator
This paper discusses the modeling and simulation of a grid-integrated photovoltaic system using a real time digital simulator. The mathematical modeling and derivation of the parameters of the PV array using an analytical and iterative procedure is discussed. The PV array is interfaced to a three-phase grid using a sinusoidal pulse width modulated voltage source converter with maximum power point tracking. A decoupled dq current control strategy is used to control the real and reactive power exchanged between the PV system and the grid. An analysis of the real-time operation of the photovoltaic system is presented.
