TES systems are divided into two categories: low temperature energy storage (LTES) system and high temperature energy storage (HTES) system, based on the operating temperature of the energy storage material in relation to the ambient temperature [17, 23]. LTES is made up of two components: aquiferous low-temperature TES (ALTES) and cryogenic
Concurrently, power electronics increasingly explores and enhances traditionally hard-wired structures such as storage and energy sources, e.g., batteries or fuel-cells, where it can enable dynamic reconfiguration or active power distribution.

The BESS is rated at 4 MWh storage energy, which represents a typical front-of-the meter energy storage system; higher power installations are based on a modular architecture, which might replicate the 4 MWh system design – as per the example below.
Traditional battery energy storage systems (BESS) are based on the series/parallel connections of big amounts of cells. However, as the cell to cell imbalances tend to rise over time, the cycle life of the battery-pack is shorter than the life of individual cells. New design proposals focused on modular systems could help to overcome this problem,

Several important parameters describe the behaviors of battery energy storage systems. Capacity [Ah]: The amount of electric charge the system can deliver to the connected load while maintaining acceptable voltage.
The PCS should be designed with this capability in mind. Peak Shaving: the battery energy storage system can discharge during periods of high demand to reduce peak load on the grid. The system should be sized appropriately to handle the expected peak demand reduction.
The major challenge now a days is to store the excess energy ,when the demand is low, and reuse this energy later or when needed. This energy can be stored in a Storage unit called „Battery‟. Power from grid connected solar PV units is generated in the form of few KW to several MW.
The output of a grid tied solar power generation which is a distributed resource can change very quickly. Solar power can be integrated into the grid by the help of Battery Energy Storage System .Real and reactive power can be absorbed and delivered by the photovoltaic systems with very few response times.
