Customer ServiceIn a world in full development of technologies related to renewable energies, progress in electrical energy storage systems plays a fundamental role. This development accompanies the promotion of sustainable energy sources and makes it possible to optimize the use of each megawatt generated, contributing to the balance of grid systems.
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
For example, when there is more supply than demand, such as during the night when continuously operating power plants provide firm electricity or in the middle of the day when the sun is shining brightest, the excess electricity generation can be used to charge storage devices.
In electrical power systems, electrical energy storage (EES) devices have been shown to improve power reliability, flexibility, and quality, and reduce electricity bills in front-of-meter and/or behind-the-meter applications, especially with the increased penetration of intermittent renewable energy (RE) generators (Ma et al., 2018).
Today's power flows from many more sources than it used to—and the grid needs to catch up to the progress we've made. What is energy storage and how does it work? Simply put, energy storage is the ability to capture energy at one time for use at a later time.
Electricity is used to compress air and store it in either an underground structure or an above-ground system of vessels or pipes. When needed the compressed air is mixed with natural gas, burned and expanded in a modifi ed gas turbine. Typical underground storage options are caverns, aquifers or abandoned mines.
