In order to mitigate energy crisis and to meet carbon-emission reduction targets, the use of electrical energy produced by solar photovoltaic (PV) is inevitable. To meet the global increasing energy demand, PV power capacity will be expanded ranging from large-scale (from ten to several hundred MWs) PV farms at high and medium
Electrical energy can be stored using different storage schemes like mechanical storage, electrochemical storage, electromagnetic storage, electrostatic storage, thermal storage etc. [16]. Depending on the characteristics, convenience and fiscal benefits some of them are preferred for large scale storage.
For utility-scale storage facilities, various technologies are available, including some that have already been applied on a large scale for decades – for example, pumped hydro (PH) – and others that are in their first stages of large-scale application, like hydrogen (H 2) storage.) storage.
Energy storage can play an important role in large scale photovoltaic power plants, providing the power and energy reserve required to comply with present and future grid code requirements.

Energy storage systems can be categorized into small and large scale systems. Small scale technologies such as batteries are mainly used by residential and industrial customers while large scale systems such as compressed air energy storage and pumped hydro are used by power suppliers [22] .
Flow batteries store energy in electrolyte solutions which contain two redox couples pumped through the battery cell stack. Many different redox couples can be used, such as V/V, V/Br 2, Zn/Br 2, S/Br 2, Ce/Zn, Fe/Cr, and Pb/Pb, which affect the performance metrics of the batteries.

Electrical Energy Storage (EES) refers to the process of converting electrical energy into a stored form that can later be converted back into electrical energy when needed.1 Batteries are one of the most common forms of electrical energy storage, ubiquitous in most peoples'' lives. The first battery—called Volta''s cell—was developed in 1800. The first U.S. large
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
