摘要
太阳能发电系统并网技术是当前太阳能应用中一个研究重点。本文提出一种有效的太阳能并网系统,其外环功率环和内环电流环分别实现了系统的功率点确定和电流的优化逆变。文中详细分析了最大功率点跟踪(MPPT)、级联五电平逆变桥控制、循环式优化算法等太阳能利用中的新技术;给出相应的仿真分析结果。
Nowadays, the technology of Grid Connected Photovoltaic Systems is one of the research emphases in the applications of the solar energy. In this paper, an efficient Grid Connected Photovoltaic System with an introduction of double-closed loops is presented. The power loop of the system implements the maximum power point tracking, and the current loop controls the invertion of current. Some new technologies used in the applications, such as MPPT, cascaded inverter and circular control theory, are analyzed de...
