Energy storage system to support power grid operation ESS is gaining popularity for its ability to support the power grid via services such as energy arbitrage, peak shaving, spinning reserve, load following, voltage regulation, frequency regulation and black start.
Techno-economic assessments (TEAs) of energy storage technologies evaluate their performance in terms of capital cost, life cycle cost, and levelized cost of energy in order to determine how to develop and deploy them in the power network.
The energy storage technologies provide support by stabilizing the power production and energy demand. This is achieved by storing excessive or unused energy and supplying to the grid or customers whenever it is required. Further, in future electric grid, energy storage systems can be treated as the main electricity sources.
Optimal coordination of energy storage systems (ESSs) significantly improves power reliability and resilience, especially in implementing renewable energy sources (RESs) [ 2 ]. The most popular ESSs used in this context are battery energy storage systems (BESS) and supercapacitors (SC).
