27.2. Energy Production and Transmission. Energy storage technologies provide grid operators with an alternative to traditional grid management, which has focussed on the ''dispatchability'' of power plants, some of which can be regulated very quickly like gas turbines, others much more slowly like nuclear plants.
The Energy Generation is the first system benefited from energy storage services by deferring peak capacity running of plants, energy stored reserves for on-peak supply, frequency regulation, flexibility, time-shifting of production, and using more renewal resources ( NC State University, 2018, Poullikkas, 2013 ).

Electrochemical capacitors. ECs, which are also called supercapacitors, are of two kinds, based on their various mechanisms of energy storage, that is, EDLCs and pseudocapacitors. EDLCs initially store charges in double electrical layers formed near the electrode/electrolyte interfaces, as shown in Fig. 2.1.
