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.
Capacitors possess higher charging/discharging rates and faster response times compared with other energy storage technologies, effectively addressing issues related to discontinuous and uncontrollable renewable energy sources like wind and solar .
This comprehensive review has explored the current state and future directions of supercapacitor technology in energy storage applications. Supercapacitors have emerged as promising solutions to current and future energy challenges due to their high-power density, rapid charge-discharge capabilities, and long cycle life.
Supercapacitors, in particular, show promise as a means to balance the demand for power and the fluctuations in charging within solar energy systems. Supercapacitors have been introduced as replacements for battery energy storage in PV systems to overcome the limitations associated with batteries [79, , , , , ].
Both supercapacitors and batteries can be integrated to form an energy storage system (ESS) that maximizes the utility of both power and energy. The key objective here is to amplify their respective strengths while minimizing their shortcomings.
Due to the benefit of high power density, the supercapacitor can store energy when the load is low. Once the circuit reaches load peak, supercapacitors release the power reserved quickly, which can lead to reducing the impact of transient energy supply problems on the microgrid.
