Energy storage systems (ESSs) in the electric power networks can be provided by a variety of techniques and technologies.
In general, storage systems are categorized based on two factors namely storage medium (type of the energy stored) and storage (discharge) duration. In the first type classification, the ESSs are divided to mechanical, chemical, and electrical storage systems based on the form in which the energy is stored.
For distribution networks, an ESS converts electrical energy from a power network, via an external interface, into a form that can be stored and converted back to electrical energy when needed , , . The electrical interface is provided by a power conversion system and is a crucial element of ESSs in distribution networks , .
Electrical energy storage systems (EESS) for electrical installations are becoming more prevalent. EESS provide storage of electrical energy so that it can be used later. The approach is not new: EESS in the form of battery-backed uninterruptible power supplies (UPS) have been used for many years. EESS are starting to be used for other purposes.
