大规模风电场并网下的互联电力系统广域阻尼协调控制
发布时间：2018-10-04 22:26
【摘要】：在区域电网互联以及大规模风电远距离输送的背景下,提出了一种新型广域阻尼控制器设计方法。该方法采用交替Krylov子空间算法对系统进行降阶,避免了传统的平衡降阶算法需处理2个高阶Lyapunov方程的问题。在此基础上,考虑了同步发电机与风电场的协调阻尼控制,提出采用均值方差映射算法对控制器参数进行协调优化。并提出增益调度思想,解决了控制器在系统不同运行方式下的鲁棒性问题。算例结果验证了所提方法的可行性。
[Abstract]:A new design method of wide-area damping controller is proposed under the background of regional power network interconnection and large-scale wind power long-distance transmission. In this method, alternating Krylov subspace algorithm is used to reduce the order of the system, thus avoiding the problem of two higher order Lyapunov equations to be dealt with by the traditional equilibrium order reduction algorithm. On this basis, the coordinated damping control of synchronous generator and wind farm is considered, and the mean variance mapping algorithm is proposed to coordinate and optimize the controller parameters. The idea of gain scheduling is proposed to solve the problem of robustness of the controller under different operation modes of the system. An example is given to verify the feasibility of the proposed method.
