BESS systems not only provide flexibility in generation, transmission and consumption such that they are able to provide an alternative energy as per the growing demand but also support power distribution.
Battery energy storage system (BESS): definition A battery energy storage system (BESS) is a large scale storage and power system which integrates batteries that are interconnected to a grid. Rechargeable batteries of lithium-ion technology are used as battery energy storage systems (BESS) which are compact in size and high in energy and power density making them suitable for deployment at the distribution transformer level. The fact that there is available space within the configuration of distribution transformers can enable the placement of battery energy storage systems. Elements of construction of the BESS storage facility include lithium battery panels, flexi glue, relay assemblies, connectors, passive devices, electric switches and other electric products.
A lithium battery consists of interconnected battery cells with each unit capable of transforming chemical energy into electric energy. The configuration consists of primary cells which are connected both in series and parallel to the main bulk of the structure. Within the bulk of the structure, there exists a module battery management system which is responsible for the oversight of the operation of the battery cells. Containers primarily designed to hold energy storage can accommodate multiple parallel battery clusters and can be enhanced with additional requirements in order to control or manage the internal environmental conditions of the container. The battery generates Direct Current (DC) which is supplied to a battery power compatible converter system then changes the voltage to Alternating Current (AC) and releases to the grid. If needed, the system can also connect to the grid to emit current from the battery.
BESS energy storage systems often have parts of the safety systems as well including the fire control systems, smoke detectors, temperature control systems and sometimes cooling, heating, ventilation and air conditioning systems. Which systems in particular will be included will be determined by the requirement to ensure reliable and safe operation of the BESS.
Compared to other energy storage systems, energy storage batteries (BESS) occupy less space and can be installed anywhere in the world without any limitations. It can have improved functionality, usability, and network security and through the BMS algorithm, the battery performance can be enhanced and the life of the battery extended.
