Simply put, energy storage is the ability to capture energy at one time for use at a later time. Storage devices can save energy in many forms (e.g., chemical, kinetic, or thermal) and convert them back to useful forms of energy like electricity. Although almost all current energy storage capacity is in the form of pumped hydro and the

Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. So, storage can increase system efficiency and resilience, and it can improve power quality by matching supply and demand.

The EV is a nonlinear load; there are many adverse effects on the grids. The EV charging has huge power requirements in a short span of time, hence affecting normal grid operations (Williamson et al. 2015) arging EV in peak demand even contributes to higher pollution as more coal has to be burnt to meet the increasing demand (Phonrattanasak

Thus, energy storage makes it possible to supply energy at peak times and storing it at off-peak times (Baker, 2008, Beltran, 2018, Chen et al., 2008).
