Capacitors 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.
2.1.1. Capacitors (Cs) Two metal plates called electrodes separated by dielectric layer form the electric capacitor. One plate is charged while the other plate is induced by an opposite sign charge . The energy is stored on the surface of the metal electrodes. This type storeenergy for extremely short periods .
The energy storage capacitor bank is commonly used in different fields like power electronics, battery enhancements, memory protection, power quality improvement, portable energy sources, high power actuators, ASDs, hybrid electric vehicles, high power actuators, off-peak energy storage, and military and aerospace applications.
These problems mainly arise on the distribution side due to the presence of nonlinear loads, unbalanced loads, and power electronics converters. The capacitor can act as an energy storage device for the system to improve power quality and reliability ( Fig. 4.19) .
