摘　　要：为了改善互联电力系统阻尼,研究了广域阻尼控制器和静止同步补偿器(STATCOM)的控制器参数全局优化方法。首先介绍了广域阻尼控制器和STATCOM及其控制器数学模型,然后描述了改进的细菌觅食优化(BFO)算法。用Matlab编程,按BFO方法优化控制器参数以使ITSE型适应度值最小。适应度值是通过解电力系统微分-代数方程求得。10机39母线新英格兰系统被用于测试协调设计方法。仿真测试表明,广域阻尼控制器和STATCOM控制器的协调设计能增强电力系统动态稳定性。A method ofglobal optimization of parameters of the wide area damping controllers and STATCOM controller is presented for improving the damping of the interconnected power system. The wide area damping controllers and STATCOM controller and its mathmatie model are introduced, and then a bacterial foraging optimization （BFO） algorithm is described. The parameters of the controllers are optimized simultaneously by using the BFO to minimize the fitness function of ITSE with Matlab. The fitness function is calculated by solving the differential-algebraic equations of power system. A 10-machine 39-bus New England system is used to test the method of the coordinated design. The test results show that the coordinated design of these controllers can enhance the dynamic stability of power system.
