Large-scale energy storage has become necessary for the safe and stable operation of the power system to suppress the volatility of wind power and photovoltaic [5, [9] [10][11]. [10][11].
Electrical energy storage (EES) cannot possibly address all of these matters. However, energy storage does offer a well-established approach for improving grid reliability and utilization.
The use of electric energy storage is limited compared to the rates of storage in other energy markets such as natural gas or petroleum, where reservoir storage and tanks are used. Global capacity for electricity storage, as of September 2017, was 176 gigawatts (GW), less than 2 percent of the world''s electric power production capacity.
