Model predictive damping control of interconnected power system based on wide-area measurement information
摘要
Abstract
Based on model predictive control,a novel damping controller design method was proposed.To damp inter-area low frequency oscillation,the controller is composed of two-level PSS,and its input signal consists of the wide-area measurement signal and the local measurement signal.Residue matrix method was used to select the wide-area control circuit and the two-level PSS are configured by mode analysis.The conventional automatic voltage regulator (AVR) in the excitation system was replaced by a model predictive controller (MPC),coordinating with two-level PSS control.The optimal control input for excitation controller is calculated by using model prediction and optimization in order to achieve dynamic coordination between voltage regulation and enhanced damping.Simulations on two-area four-machine power system demonstrated that the two-level PSS controller based on model predictive control can provide better control performance than the conventional damping control in regulating terminal voltage and enhancing damping.It can quickly regulate the terminal voltage and better improve the damping level of power grid.关键词
