Abstract
This article proposes a supercapacitor (SC)-based energy storage system (ESS) connected to the common DC link of a DC microgrid (MG) through a bidirectional DC/DC converter. The studied DC MG consists of a hybrid wind/PV/wave power generation system (PGS) fed to a DC load through a DC/DC buck converter. The proposed SC-ESS is to achieve both power management and DC-link voltage control of the DC MG under various operating conditions. The simulation results show that the proposed SC-ESS can render better DC grid resilience enhancement and dynamic stability improvement to the DC MG under various disturbance conditions and severe weather conditions.
