But before that is discussed, it is necessary to consider the basic aspects of energy storage in magnetic systems.
There are two general approaches to the solution of these types of requirements. One involves the use of electrical devices and systems in which energy is stored in materials and configurations that exhibit capacitor-like characteristics. The other involves the storage of energy using electromagnets. These are discussed in the following sections.

(1) When the short is opened, the stored energy is transferred in part or totally to a load by lowering the current of the coil via negative voltage (positive voltage charges the magnet). The Superconducting Magnetic Energy Storage (SMES) is thus a current source [2, 3]. It is the “dual” of a capacitor, which is a voltage source.
For an energy storage device, two quantities are important: the energy and the power. The energy is given by the product of the mean power and the discharging time. The diagrams, which compare different energy storage systems, generally plot the discharging time versus power.
Batteries and the BMS are replaced by the “Energy Storage Medium”, to represent any storage technologies including the necessary energy conversion subsystem. The control hierarchy can be further generalized to include other storage systems or devices connected to the grid, illustrated in Figure 3-19.
