Purpose: Backup batteries provide electricity during outages and lower electric bills, while self-consumption batteries only reduce electric bills. They don't provide power during blackouts.
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.
Battery storage is one of several technology options that can enhance power system flexibility and enable high levels of renewable energy integration.
Battery energy storage system (BESS) has been applied extensively to provide grid services such as frequency regulation, voltage support, energy arbitrage, etc. Advanced control and optimization algorithms are implemented to meet operational requirements and to preserve battery lifetime.
For example, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours. Cycle life/lifetime is the amount of time or cycles a battery storage system can provide regular charging and discharging before failure or significant degradation.
The nature of rechargeable batteries, charging for down-regulation and discharging for up-regulation with immediate response and adjustable power scale is the inherent advantage compared with other components in the power system.

Hybrid energy storage systems (HESS), which combine multiple energy storage devices (ESDs), present a promising solution by leveraging the complementary strengths of each technology involved. This comprehensive review examines recent advancements in grid-connected HESS, focusing on their components, design considerations, control strategies.
Energy storage technologies can potentially address these concerns viably at different levels. This paper reviews different forms of storage technology available for grid application and classifies them on a series of merits relevant to a particular category.
In this context, energy storage systems (ESSs) are proving to be indispensable for facilitating the integration of renewable energy sources (RESs), are being widely deployed in both microgrids and bulk power systems, and thus will be the hallmark of the clean electrical grids of the future.
However, no single storage technology can effectively address all grid stability and reliability requirements. This is where the hybrid energy storage systems come into play. HESS combines different energy storage technologies to provide short-term high power output and long-term energy storage solutions (Y. Wang et al., 2020).
Therefore, the application technology of the battery energy storage system is used to support the impact of changes in the new power system structure. This paper designed control technologies based on the WECC second-generation generic model, namely, dynamic regulation, steady regulation, and virtual inertia regulation.
The development and expansion of energy storage technology not only depend on the improvement in storage characteristics, operational control and management strategy, but also requires the cost reduction and the supports from long-term, positive stable market and policy to guide and support the healthy development of energy storage industry.
Due to rapid development of energy storage technology, the research and demonstration of energy storage are expanding from small-scale towards large-scale. United States, Japan, the European Union have proposed a series of policies for applications of energy storage technology to promote and support industrial development [12 – 16].
