Hybrid Energy Storage Performance Evaluation of Fuel Cell Injection on Standalone Photovoltaic System

Abstract

In this research, some performance evaluations of battery as the main storage
and supercapacitor as the supporting storage in a hybrid energy storage system were
carried out to determine the recommendations of whether fuel cells could be integrated
into a standalone photovoltaic system. In previous studies, the fuel cell circuit was judged
to be quite different by integration with a standalone photovoltaic system, and in this
study, observations were made on aspects of power quality such as voltage, current, and
power for the two energy storage systems. The research method is using simulation as the
medium with several self-definition aspects on photovoltaic, fuel cell, battery, and
supercapacitor, also with their parameters. The result shows that on the battery, the fuel
cell integration has no particular effect since the battery is the main storage, and the
voltage and current had minor perturbation. While in a supercapacitor, major
perturbation from the system had been absorbed due to the fuel cell integration
characteristic of giving major perturbation to the system. The main recommendation is by
choosing supporting storage instead of using both supercapacitors and fuel cells.
