摘　　要：针对大区域电网互联以及大规模双馈风电场并网所面临的区域低频振荡问题,提出一种综合考虑同步发电机与双馈风力发电机的广域阻尼控制策略;并采用一种迭代次数较少、不易陷入局部最优解的新型优化算法——均值方差映射算法进行控制器参数协调配置,通过与传统智能算法的比较,证明了该方法的优越性;含双馈风电场的四机两区测试系统的仿真结果表明,提出的方法能有效提高大规模双馈风电场并网背景下的互联电力系统区域低频振荡阻尼能力。A wide-area damping control strategy comprehensively considering synchronous generators and doubly fed induction generators was proposed which is based on the interarea low frequency oscillation problem caused by large area interconnected power grid and massive grid connected doubly fed wind farms. Also, a new optimization algorithm called Mean-Variance Mapping Optimization algorithm with the advantage of fewer iterations and not easy to fall into local optimal solution was adopted to coordinate the configuration of controller parameters. And the superiority of this new method is proved by contrast with the traditional intelligent algorithms. At last, interarea low frequency oscillation problem in interconnec-ted power systems with massive grid connected doubly fed wind farms was effectively solved by the pro-posed method, which is validated by the simulation results a four-machine and two-region test system with a doubly fed wind farm.
