Technologies and economics of electric energy storages in power
The energy storage capacity could range from 0.1 to 1.0 GWh, potentially being a low-cost electrochemical battery option to serve the grid as both energy and power sources. In the last decade, the re-initiation of LMBs has been triggered by the rapid development of solar and wind and the requirement for cost-effective grid-scale energy storage.
Flexibility enhancement of combined heat and power unit
Combined heat and power (CHP) unit operates in a heat-dominating mode, which reduces the flexibility and makes it impossible to absorb renewable energy on a large scale. By coupling grid-side and source-side thermal energy storage (TES) system to traditional CHP unit, the feasible and safe operation region of the plant is expanded.

Grid Energy Storage
Introduction. Grid energy storage is a collection of methods used to store energy on a large scale within an electricity grid. Electrical energy is stored at times when electricity is plentiful and cheap (especially from variable renewable energy sources such as wind and solar), or when demand is low, and later returned to the grid when demand is high and electricity prices tend to be higher.
