In this study a flywheel (FW) system, which is integrated in the rotor of a wind turbine (WT), is proposed. It is made of hydraulic–pneumatic piston accumulators and its primary purpose is to provide the power system with inertia. Power system inertia is an essential premise for primary frequency control. The equations describing the system are presented. Simulation results show that the performance of such a FW system is superior to the commonly used approach of using WTs to provide the power system with so‐called synthetic inertia.
