Customer ServiceCapacitors exhibit exceptional power density, a vast operational temperature range, remarkable reliability, lightweight construction, and high efficiency, making them extensively utilized in the realm of energy storage. There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors.
The merits and demerits of energy storage capacitors are compared with the other energy storage units. The basic need of an energy storage system is to charge as quickly as possible, store maximum energy, and discharge as per the load demand.
Providing reliability in both generations and supplying energy storage devices plays a very important role. Among all energy storage devices, the capacitor banks are the most common devices used for energy storage. The advantage of capacitor banks is, that they can provide very high current for short period.
