A novel experimental method of power smoothing using supercapacitors and hydrogen for hybrid system PV/HKT

Nowadays, the intermittent nature of renewable energy systems represents one of the most significant challenges in isolated systems, where power fluctuations can cause instability and compromise energy quality. Although hydrogen systems and supercapacitors have been widely studied in the literature,...
