Contribution to frequency control through wind turbine inertial energy

An innovative way for wind energy to participate in some sort of frequency control using kinetic energy stored in the rotor for a fast power reserve that could be delivered in a short period (from several seconds up to a few tens of seconds) is presented. This kinetic-energy-based fast reserve is ensured despite wind speed variations - a disoptimisation of the power

(PDF) Grid inertial response with Lithium-ion battery energy storage

Thus, the generator rotating mass behaves as a kinetic energy storage and provides inertial response (IR). Modern wind power plants (WPPs) are commonly equipped with power electronic interfaces, which decouple the generator speed from the grid frequency. Therefore, the IR of RES is not as inherent as it is in the case of CPPs [4].
