摘要
风电机组输出功率随机波动性强影响电网安全稳定运行,为进一步提高电网稳定运行,设计了一种基于迭代学习控制策略(ILC)的水电机组控制方法,使其能够快速平衡由于风电和负荷变化而引起的功率偏差,从而实现系统频率稳定。在Matlab/Simulink中建立了水电机组调节系统仿真模型,对三种不同的风电功率扰动工况进行了仿真研究,并将控制效果与传统PID控制进行对比。仿真结果表明,基于ILC建立的控制器能使系统频率在风电功率扰动下具有较好的动态性能。
The strong random fluctuation of the output power of wind turbines affects the safe and stable operation of the power grid.In order to further improve the stable operation of the power grid,this paper designs a control method for hydropower generators based on iterative learning control strategy(ILC),which can quickly balance the changes of power deviation caused by wind power and load so as to achieve system frequency stability.In Matlab/Simulink,a simulation model of hydropower unit regulation system is established to simulate three different wind power disturbance conditions.The control effect is compared with the traditional PID control.The simulation results show that the controller based on ILC can make the system frequency have better dynamic performance under wind power disturbance.
