Energy Storage Systems can be considered as generation, connected directly to the grid, when they deliver energy, and as demand, when they are drawing energy to charge the energy storage. The advantages of energy storage in these cases are based on its lower cost, speed of response, and ease of location near the load.
At present, the cost–benefit analysis of energy storage in the literature is mostly based on the specific application scenario of a certain type of energy storage.

Community shared energy storage (CSES) can play a crucial role in relieving the uncertainty of renewable energy resources [ 3 ]. CSES stores excess energy generated by renewable sources during low-demand periods and injects that energy during high-demand periods. Accordingly, energy storage systems can reduce the demand on
From a macro-energy system perspective, an energy storage is valuable if it contributes to meeting system objectives, including increasing economic value, reliability and sustainability. In most energy systems models, reliability and sustainability are forced by constraints, and if energy demand is exogenous, this leaves cost as the main metric for

In power-type energy storage applications, [17] calculated not only battery storage cost per kilowatt-hour, but also that per mileage corresponding to mileage compensation in the electricity market. In the LCOS method, the capacity decay of battery storage is simplified by taking the average value, which results in relatively low accuracy.
