Energy storage systems are used in the power grid to solve imbalances between electricity demand and supply. They can be used in various stages of the process, including power generation, transmission, transformation, distribution, and final consumption.
Utilizing energy storage systems as power generation resources primarily involves the system taking over the electricity supply function that generators in existing power systems are typically responsible for. Energy storage systems can be used both for moving electric supply (differential trading) and as an electric supply capacity.
The deployment of energy storage systems (ESS) can also create new business opportunities, support economic growth, and enhance the competitiveness of the power market. There are several ESS used at a grid or local level such as pumped hydroelectric storage (PHES), passive thermal storage, and battery units [, , ].
Therefore, energy storage systems provide emergency power quickly and even act as an independent power source during long-term power outages, preparing the power system for emergency situations. An energy storage system (ESS), while installed for specific purposes, can be used for other purposes as well, as seen in Table 4.
An Energy Storage System consists of storage devices (such as reservoirs, compressed air storage, batteries), conversion devices (such as Power Conditioning Systems (PCSs), compressors/expansion engines, generators), and control devices. Figure 2 shows the basic components of an Energy Storage System using a battery (lithium-ion cell).
Electrochemical storage systems, such as batteries and supercapacitors, are commonly used in small-scale and distributed energy storage applications. Mechanical storage systems, such as PHES and flywheels, are widely used in large-scale energy storage applications.
