摘要 可再生新能源利用的关键技术是将其转化为可并入电网的电能必须满足电网的电压和频率的要求。介绍了采用下垂控制对直流微电源并网控制的分析研究,经电压控制器、电流控制器对并网逆变器进行双环控制,使得到电压和频率满足并网的要求,还对系统负荷突变、电压跌落、三相短路等3种情况进行了仿真分析,仿真结果表明在这3种故障情况下,含直流微电源的并网系统仍能稳定运行,并能跟踪系统的动态输出。 The key technology of renewable energy application is to guarantee that the power energy for its conversion and grid integration must meet the requirements of grid voltage and frequency. In this paper, the droop control of grid-connected DC micro power is analyzed. The voltage controller and current controller are employed for the dual- loop control of the grid-connected inverter in accordance with grid integration requirements for voltage and frequency. The three kinds of system faults, namely, load mutation, voltage drop and three-phase short-circuit are simulated and analyzed. It is shown that the grid system including DC micro power can run steadily in three faulty conditions, and can track the dynamic output of the system smoothly.
