Grid-scale energy storage projects complement renewables by storing energy and dispatching it during periods of low wind or sunlight, creating a more resilient energy system.
Shared energy storage is generally applied in the supply, network, and demand sides of power systems. The shared energy storage at the supply side is mainly utilized for renewable energy consumption (Zhang et al., 2021). The proportion of renewable energy is greatly increasing due to the continuous promotion of "carbon peaking and neutrality".
CES is a shared energy storage technology that enables users to use the shared energy storage resources composed of centralized or distributed energy storage facilities at any time, anywhere on demand. Users won''t need to build their ESS but pay for the energy storage services they obtain.
