基于新型自抗扰控制方法的风火协同调频策略研究
Coordination frequency regulation strategy of wind-thermal power based on novel active disturbance rejection control method
摘要
Abstract
With the increase of wind power penetration in power systems,the inertia of the power system decreases and the frequency regulation resources are insufficient.The frequency response margin approaches the critical value,which results in great challenges to frequency security.To solve the problem,from the perspective of regulation mechanism,a wind-thermal cooperative frequency control model based on virtual inertia control of wind power is constructed.The kinetic energy of rotor is used for fast frequency regulation.Then,a load frequency controller of wind-thermal cooperative power system based on a novel active disturbance rejection control(ADRC)method is proposed and designed.This improves the anti-disturbance capability to uncertain wind power and load disturbances.The designed cascade extended state observer also solves the contradiction between high frequency noise suppression and fast response performance of conventional ADRC.The excessive regulation of wind power and thermal power units caused by frequency measurement noise can be avoided and the quality of wind-thermal coordination regulation can be improved.Finally,genetic algorithm based particle swarm optimization is used to optimize the parameters of the proposed load frequency controller.The simulation results show that,compared with the conventional ADRC and other conventional control methods,the proposed strategy can effectively improve the frequency response characteristics,and suppress the effect of measurement noise on the amplitude of system frequency response and control signal.关键词
