Load Frequency Control for Power Systems with Wind Turbines
In this paper,a two-degree-freedom(TDF)internal model control(IMC)method is applied to the load frequency control(LFC)of multi-area power systems with of wind turbines.TDF-IMC needs only to tune two parameters and can achieve good disturbance rejection performance.For implementation,IMC controllers are approximated with PID controllers.A frequency response dynamic model including simplified wind turbine is used in the design and simulation,and the physical constraints such as generation rate constraint(GRC)and speed governor dead band are considered.Simulation results show that the proposed method can damp the frequency and tie-line exchange power deviation quickly,and is robust to parameter variations.Furthermore,the participation of wind turbines in LFC can enhance the total system performance.
