| 摘 要： | 针对含分布式能源（DER）的微电网在孤岛运行模式下自身调节能力有限的问题，基于反步控制方法设计了一种DER系统孤岛运行电压控制策略，解决了DER系统在孤岛运行模式下的电压控制问题.首先，给出了孤岛运行模式下DER系统模型及输出电压数学模型；其次，利用反步控制方法设计了控制器，同时利用李雅普诺夫稳定性理论进行了稳定性分析；最后，利用此控制器在平衡负载及不平衡负载的情况下对输出电压进行控制，并通过仿真验证了反步控制器的有效性.

| Abstract: | According to the problem of limited self-adjustment ability of microgrid with distributed energy resource (DER) under islanding operation mode, a control strategy based on backstepping control method is designed, which solves the voltage control problem of DER system in islanding operation mode.Firstly, the system model and the mathematical model of output voltage of islanded DER system are given.Secondly, the controllers are designed by using backstepping control method step by step, and the stability analysis is proved by using the Lyapunov stability theory.Finally, the designed controllers are used to control the output voltage under balanced load and unbalanced load, and the effectiveness of the backstepping controllers is verified by simulation. |
