Control Mechanisms of Energy Storage Devices | IntechOpen
Therefore, a negative feedback signal is used in the CES control loop to provide a fast voltage recovery. Thus, Eq. 7 is rewritten in following form: ΔId = 1 1+sTdc (KcΔf − KEdΔEd) Δ I d = 1 1 + sT dc K c Δ f − K Ed Δ E d E8. where KEd K Ed is the negative feedback gain of the capacitor voltage deviation (kA/kV).

Energy Storage Device
7.2.2.1 Inductors. An inductor is an energy storage device that can be as simple as a single loop of wire or consist of many turns of wire wound around a core. Energy is stored in the form of a magnetic field in or around the inductor. Whenever current flows through a wire, it creates a magnetic field around the wire.
