抑制风水系统输出振荡的附加协同-滑模控制设计
Design of additional synergetic-sliding mode control for suppressing output fluctuation of wind-hydro system
摘要
Abstract
In order to suppress the impact of wind power fluctuations on other units in the system,tar-geting the wind-hydro complementary system,the hydropower units in the wind-hydro system were taken as the core control objects,aiming to realize the joint regulation of wind-hydro units by integra-ting the synergetic control and sliding mode control theory.Firstly,the mechanical power,angular ve-locity,and active power of wind turbines were selected as macroscopic variables,and the coordinated control signal of additional controller was defined.Subsequently,a synergetic control-integrated sli-ding mode surface was designed,and a design method for an additional synergetic sliding mode control-ler was proposed.This method retained the system's original PID controller,introduced the state varia-bles of the wind and water turbine units into the controller to derive the control law.The control law was then introduced into the power angle control differential equations in the form of additional feedback to achieve system model improvement and coordinated unit control.The simulation results show that the out-put oscillation of the hydropower unit output is reduced from±0.10 to±0.02 when the wind turbine un-dergoes sinusoidal changes,while the active power,reactive power,and angular velocity outputs of the combined system are reduced to half of their original values.This proposed method can effectively sup-press the output oscillations and enhance the output stability of the combined wind-hydro system.关键词
