Activation schemes of synthetic inertia controller on full converter wind turbine (type 4)

One of the challenges in future energy systems is the massive use of high power converters that decouple new energy sources from the AC power grid, disabling natural frequency response. This situation decreases the total system inertia affecting the ability of power system to overcome system frequen...
