本文介绍、制定并评价了一种基于线路换向直流线路补充电流控制的抑制电力系统区域间振荡的方法。所提出的控制是基于模型预测控制（MPC）策略。与其他最优控制策略（例如线性二次高斯（LQG）控制）相比，MPC的显著特征是它在明确尊重植物约束的同时调整控制信号以实现目标。本文还比较了MPC和LQG控制的性能。在西方系统协调委员会（WSCC） 9总线系统和IEEE 14总线系统上对这两种方法进行了测试。进行了小信号干扰和大信号干扰稳定性研究，以证明和比较LQG和MPC方法的性能。研究结果表明，MPC对测试系统的弱阻尼振荡模式具有良好的抑制效果。
This paper introduces, formulates and evaluates an approach for damping inter-area oscillations of power systems based on supplementary current control of a line-commutated HVDC link. The proposed control is based on the model predictive control (MPC) strategy. The salient feature of the MPC as compared with other optimal control strategies, e.g., the linear quadratic Gaussian (LQG) control, is that it adjusts the control signal to achieve the objectives while explicitly respecting the plant constraints. This paper also compares the performance of the MPC with that of the LQG control. The two approaches are tested on the Western System Coordinating Council (WSCC) 9-bus system and the IEEE 14-bus system. Small-signal disturbance and large-signal disturbance stability studies are performed to demonstrate and compare the performances of the LQG and MPC methodologies. The study results show the effective and superior performance of the MPC for damping poorly damped oscillatory modes of the test systems.
