A wind farm supervisory control (WFSC) is developed to generate the active power reference to the RSC and GSC. WTG controllers then regulate each DFIG wind turbine to generate the desired amount of active power, where the deviations between the available wind energy input and desired active power output are compensated by the ESS. Simulation is done in Matlab for the grid connected wind farm, the wind farm consists of 15 DFIG wind turbines each with 4MW capacity at different and constant wind speeds. A constant active power Pref is taken at 38MW which can be specified by the grid operator and the wind farm has to supply this constant active power. Simulation results are studied for the active power supplied by wind farm with and without Energy Storage System (ESS). Here we can observe that with ESS the active power supplied by wind farm is almost constant. 2. Doubly-Fed Induction Generator Systems For variable-speed systems with limited variable-speed range, e.g. ±30% of synchronous speed, the DFIG can be an interesting solution. As mentioned earlier the reason for this is that power electronic converter only has to handle a fraction (20–30%) of the total power. This means that the losses in the power electronic converter can be reduced
