To meet these gaps and maintain a balance between electricity production and demand, energy storage systems (ESSs) are considered to be the most practical and efficient solutions. ESSs are designed to convert and store electrical energy from various sales and recovery needs [, , ].
How do we store energy electrically?
If we want to store energy electrically, we can do this either through a voltage storage or a current storage. Inductance, or more precisely a superconducting inductance, serves as the current storage. The construction and functioning of such a superconducting magnetic energy storage (SMES) system is described in this chapter.
Why is energy storage important?
Renewable energy sources such as wind and solar are intermittent.
