Energy flow management of a hybrid renewable energy system with hydrogen

Abstract

This paper presents a preliminary study on a hybrid renewable energy system at the Ostfalia University of Applied Sciences Wolfenbüttel, Germany. The test-bed is made up of solar photovoltaics (PV), a micro wind turbine (MWT), a micro-CHP, a fuel cell system (FC), and two storage devices (a battery system and an electrolyzer). All the installations are in the range of 1 to 6 kW electrical power output/input; the focus of this research is renewable energy systems for residential applications. In addition to the presentation of experimental test results, a model of the hybrid system will be introduced.
