基于LADRC的匹配控制构网型PMSG快速频率支撑策略
Fast frequency support strategy of grid-forming PMSGs based on LADRC with matching control
摘要
Abstract
To enhance the frequency support characteristics of grid-forming(GFM)wind turbines under matching control,and to overcome the poor adaptability of single control strategies and fixed parameters to varying power grid operating conditions,this paper proposes a fast frequency support strategy for GFM permanent magnet synchronous generator(PMSG)wind turbines based on linear active disturbance rejection control(LADRC).First,a GFM control architecture of grid-connected PMSG based on matching control is constructed,and the matching mechanism between DC voltage and frequency is explained.Second,an LADRC-based frequency support strategy for matching control GFM PMSGs is designed,and the influence of controller bandwidth parameters on the disturbance rejection capability of LADRC is analyzed.Then,a genetic algorithm(GA)is integrated to perform online optimization of the bandwidth parameters in LADRC,endowing the controller with a certain degree of self-tuning capability.Finally,comparative analyses of grid frequency and wind turbine power output under different operating conditions and control strategies are conducted using the PSCAD/EMTDC simulation platform.Simulation results show that the proposed strategy can enhance the frequency support capability of grid-connected wind power systems under various scenarios.关键词
