Impact of inertial response for the variable speed wind turbine

Discussion on the impacts of real inertia of the wind turbine which is prevailing naturally and artificially controlled because the inertia of wind turbine is not consistent due to wind speed, the speed of the turbine and the torque of the turbine. Nowadays, the preservation of natural resources are becoming more important to replace the conservation energy sources due to global warming and environment changing etc. Therefore, so many techniques are taken to control the wind turbine output according to the variable wind speed. In this research work, IG wind turbine and DFIG wind turbine are used to accumulate the frequency deviation and wind turbine rotor speed using a PI controller for an only DFIG turbine named speed controller. There is also a comparison between the fixed speed wind turbine and the variable wind turbine to control the inertial impact of the variable speed of the turbine rotor at the variable wind speed.
