Constructing a new power system with renewable energy as the main body is an important way to achieve the goal of carbon emission reduction. However, uncertainty and intermittency of wind and solar power generation lead to a dramatic increase in the demand for flexible adjustment resources, mainly hybrid energy storage.
Renewable energy generation can depend on factors like weather conditions and daylight hours. Long-duration energy storage technologies store excess power for long periods to even out the supply. In March 2024, the House of Lords Science and Technology Committee said increasing the UK''s long-duration energy storage capacity would support the
The economic value of energy storage is closely tied to other major trends impacting today''s power system, most notably the increasing penetration of wind and solar generation. However, in some cases, the continued decline of wind and solar costs could negatively impact storage value, which could create pressure to reduce storage costs in order

Mainstream wind power storage systems encompass various configurations, such as the integration of electrochemical energy storage with wind turbines, the deployment of compressed air energy storage as a backup option, and the prevalent utilization of supercapacitors and batteries for efficient energy storage and prompt release [16, 17]. It is
From a technical perspective, an ESS involves three processes: a) discharging electrical power from the power grid; b) transforming energy into an appropriate way for storage, and c) converting and redirecting electricity to the grid (EPRI, 2010). Through these processes, energy is stored with reduced generation costs when electricity demand is low and with high
