摘　　要：针对互联电网中时滞因素影响广域控制效果的问题,提出了一种基于蝙蝠算法的广域阻尼控制策略,该方法对时滞环节采用Pade逼近近似处理,并利用蝙蝠算法对广域控制器进行优化,将机电振荡模态的阻尼比做为目标函数,分别讨论了不同时滞、多个输入以及多输入多输出的阻尼控制器优化设计,并给出在两区四机系统中的仿真结果,结果表明:采用蝙蝠算法设计的广域阻尼控制器能有效地抑制区间振荡模式,且多输入多输出的广域控制器控制效果要优于单输入单输出的广域控制器。Aiming at the problem that the time delay factor in the interconnected power system affects the wide-area control effect,a wide-area damping control strategy based on the bat algorithm is proposed in this paper.In this method,the time delay is approximated by Pade approximation,and the bat algorithm is used to optimize wide-area controller. The damping ratio of the electromechanical oscillation mode is used as the objective function.The damping controller optimization designs with different time delays,multiple inputs,and multi-input and multi-output are discussed respectively, and simulation results in two-area and four-machine system are given. The results show that the wide-area damping controller designed by bat algorithm can effectively suppress interval oscillation mode, and the control effect of the multi-input multi-output wide-area controller is better than that of the single-input and single-output wide-area controller.
