TCSC非线性最优预测控制器的设计
A nonlinear optimal predictive controller for TCSC
【摘要】 基于非线性最优预测控制(NOPC)理论,设计了一种具有闭合的解析控制律的可控串联补偿电容器(TCSC)的控制器。该控制器不要求进行在线优化计算,从而避免了大量的计算负担,且其可调参数只有二个(滚动预测时间T及控制阶r),因而它完全满足实时控制的要求,且便于工程实现及调试。仿真结果表明,该控制器在提高系统的稳定性、阻尼系统振荡方面有明显的改善。
【Abstract】 In this paper,a novel controller for thyristor-controlled series capacitors(TCSCs) with closed-form analytical solution nonlinear optimal predictive control(NOPC) is presented.This controller does not require on-line optimization,so the huge calculation burden can be avoided and the demand of real-time control can be satisfied.In addition,there are only two design parameters(predictive period T and control order),thereby it is easy to be implemented in practice.The simulation results show that the controller can greatly improve power system stability and effectively attenuate power system oscillation.
【Key words】 nonlinear optimal predictive control; thyristor-controlled series capacitor; stability; damping;
