Hybrid renewable energy systems (HRES) help to increase system reliability and improve power quality.
However, they face certain challenges in their widespread deployment such as intermittently varying
renewable energy (RE) sources like solar radiation and wind speed, high installation costs and limited
lifetime of energy storage devices. Thus, there is a need to integrate these sources by means of a suitable
power management strategy (PMS) despite the fluctuations in source and load power. This paper aims to
formulate a PMS to integrate the power output from solar photovoltaic (PV) array, fuel cell (FC) stack and
battery with a provision for onsite hydrogen (H2) generation by means of an electrolyzer and H2 tank. The
control strategy handles the source power effectively by considering the limited lifecycle of storage
devices. It also eliminates the need for a dump load in the system by matching the source power with
load demand when the storage devices are charged to their maximum capacity.
