Fast frequency support strategy of grid-forming PMSGs based on LADRC with matching control
为提升匹配控制构网型(grid-forming,GFM)风电机组联网频率支撑特性,同时解决单一的控制策略和参数对电网运行工况适应性差的问题,提出一种基于线性自抗扰控制(linear active disturbance rejection control,LADRC)的匹配控制构网型永磁直驱风电机组(permanent magnet synchronous generator based wind generator,PMSG)快速频率支撑策略.首先,构建基于匹配控制的构网型PMSG控制架构并阐述直流电压与频率的匹配机理.其次,设计匹配控制构网型PMSG的LADRC频率支撑策略,并分析控制器带宽参数对LADRC抗扰能力的影响规律.然后,结合遗传算法(genetic algorithm,GA)对LADRC中的带宽参数进行在线寻优,使其具备一定的参数自整定能力.最后,基于PSCAD/EMTDC仿真平台,对不同控制策略在不同工况下电网频率和风机出力的变化情况进行对比分析.仿真结果表明,所提策略可在多种场景下提升风电联网系统对电网频率的支撑能力.
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.
