Energy storage can smooth out or firm wind- and solar-farm output; that is, it can reduce the variability of power produced at a given moment. The incremental price for firming wind power can be as low as two to three cents per kilowatt-hour. Solar-power firming generally costs as much as ten cents per kilowatt-hour, because solar farms

The daily non-uniform power demand is a serious problem in power industry. In addition, recent decades show a trend for the transition to renewable power sources, but their power output depends upon weather and daily conditions. These factors determine the urgency of energy accumulation technology research and development.
Based on an analysis of the results of demand management and energy storage scheduling period-setting, we established a bi-level optimal sizing model of user-side energy storage that can be transformed into a single-level MILP model for optimization.
Energy storage systems play an increasingly important role in modern power systems. Battery energy storage system (BESS) is widely applied in user-side such as buildings, residential communities, and industrial sites due to its scalability, quick response, and design flexibility [1], [2] .
Driven by global concerns about the climate and the environment, the world is opting for renewable energy sources (RESs), such as wind and solar. However, RESs suffer from the discredit of intermittency, for which energy storage systems (ESSs) are gaining popularity worldwide. Surplus energy obtained from RESs can be stored in
Storage can provide similar start-up power to larger power plants, if the storage system is suitably sited and there is a clear transmission path to the power plant from the storage system''s location.

energy consumption can be reduced, more efficient systems can be facilitated and are cost effective. The share of renewable energy can be increased by the way of such thermal energy storage
The different types of energy storage can be grouped into five broad technology categories: Batteries. Thermal. Mechanical. Pumped hydro. Hydrogen. Within these they can be broken down further in application scale to utility-scale or the bulk system, customer-sited and residential.
While both approaches do not mention competitiveness or the value of energy storage, their outputs combined with cost and benefit analysis allows finding the value of energy storage solutions. The levelised cost approaches for energy storage include metrics such as the levelised cost of storage when electricity is discharged
Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today. Of the remaining 4% of capacity, the largest technology shares are molten salt (33%) and lithium-ion batteries (25%). Flywheels and Compressed Air Energy Storage also make up a large part of the market.
