摘要
对现有光伏发电系统并网逆变器控制策略的特点进行了分析、讨论和总结。对较实用的电压源输入、电流源输出中,基于电流闭环与功率闭环的多种内环控制方式进行了评述。最后,对并网逆变器控制策略在光伏系统中的发展方向进行了展望。
The existing photovohaic power system ＇ s grid-connected inverter control strategies were summarized and discussed, and their characteristics were analyzed. In the more practical voltage source input current output, multiple inner loop control methods based on current closed loop and power closed loop were expounded. Finally ,the control strategy of grid-connected inverter in the direction of development of photovoltaic system was prospected.
