1. Introduction The energy industry is a key industry in China. The development of clean energy technologies, which prioritize the transformation of traditional power into clean power, is crucial to minimize peak carbon emissions and achieve carbon neutralization (Zhou et al., 2018, Bie et al., 2020).).
This energy storage can be used to smooth out power usage and seamlessly transition to an always-on battery-enabled power supply whenever needed. By doing so, organizations can reduce OpEx costs, such as peak demand charges, on an ongoing basis. They can also participate in energy arbitrage and other services, enhancing profitability.
Storage can provide similar start-up power to larger power plants, if the storage system is suitably sited and there is a clear transmission path to the power plant from the storage system''s location. Storage system size range: 5–50 MW Target discharge duration range: 15 minutes to 1 hour Minimum cycles/year: 10–20.
Energy storage is an integral part of any critical power system, as this stored energy is used to offset interruptions in the power delivered from either a utility or an on-site generator. Traditionally, capacitors are used for short-term storage (µs-ms)
