Supercapacitors have been introduced as replacements for battery energy storage in PV systems to overcome the limitations associated with batteries [79, , , , , ].
However, batteries suffer from a drawback in terms of low power density. In recent years, supercapacitor devices have gained significant traction in energy systems due to their enormous power density, competing favorably with conventional energy storage solutions.
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.
In this configuration, the PV array serves as the primary power source, while the supercapacitor functions as the energy storage device mitigating uncertainties in both steady and transient states . The incorporation of a supercapacitor in this system enhances power response, improving both power quality and efficiency.
The size and application make the constructional features of supercapacitors different from those of conventional capacitors. Accordingly, based on the fundamental principle of charge storage mechanisms, supercapacitors are further classified as Electrochemical double-layer capacitors (EDLC), pseudocapacitors, and hybrid supercapacitors.
