摘要：本文提出了一种基于广义预测控制（GPC）和模型辨识的自适应广域调节控制器（WADC），用于抑制大尺度互联电力系统的域间低频振荡。应用具有不同遗忘因子的递归东平方算法（RLSA）来识别包含主要区域间允许低频振荡的线性线性化模型。在此线性初始化模型的基础上，采用了考虑控制输出约束的广义预测控制方案，以获得采样区间内的最佳控制信号。39�Casestudiesareundertakenonatwoareafour�machinepowersystemandtheNewEngland机器�10���buspowersystem,分别�。仿真结果表明，所提出的自适应wadc不仅能在较宽的工作条件范围和不同的干扰下有效地抑制区域间振荡，而且对信号中存在的时延具有较好的鲁棒性。�Thecomparisonstudies�withtheconventionalleadlagWADCarealsoprovided。
