Abstract Primary frequency controls for wind turbine are discussed. Variable speed wind turbine connected with hydro turbine is simulated using Simulink/Matlab. Different scenarios are analyzed and compared, where several primary frequency control are used to support the frequency response after system disturbance with two different cases of wind speed, the first is high wind speed and the second is low wind speed. The thesis proposes two new controllers’ structure based on combination strategy between different controllers. The best combined controller that leads to reducing the rate of change of frequency and raising the frequency nadir |
