Then, an energy storage optimisation plan is developed with the goal of minimizing the cost of the energy storage system and the power fluctuations of distributed sources (Wang et al. 2023).

How does energy-to-power ratio affect battery storage?

The energy-to-power ratio (EPR) of battery storage affects its utilization and effectiveness. Higher EPRs bring larger economic, environmental and reliability benefits to power system. Higher EPRs are favored as renewable energy penetration increases. Lifetimes of storage increase from 10 to 20 years as EPR increases from 1 to 10.

What is the difference between rated power capacity and storage duration?

Rated power capacity is the total possible instantaneous discharge capability of a battery energy storage system (BESS), or the maximum rate of discharge it can achieve starting from a fully charged state. Storage duration, on the other hand, is the amount of time the BESS can discharge at its power capacity before depleting its energy capacity.
