Investigation of the reactions exhibited by the system in relation to different loads in a sample house powered with a hybrid photovoltaic-hydrogen/fuel cell

Abstract

In today's world where energy resources are rapidly depleted and great importance is attached to clean, environmental friendly, modular and fossil fuel-independent energy sources, "photovoltaic-hydrogen fuel cell hybrid energy production systems" come into prominence. In our university, there is a Clean Energy House and here, there is already a 5kWP photovoltaic and 2.4kWP hydrogen fuel cell power system established. Here, electric energy is produced through photovoltaic panels mounted on sun tracking half of which are fixed and the other half is liquidbased, the energy produced is stored in batteries with 28.8kWh storage capacity and some of the stored energy is consumed to meet the internal energy needs of the clean energy house through 5kW-220V/50Hz thoroughly sinus inverter, the rest is used to power a hydrogen generator. Hydrogen generated from the city water through the hydrogen generator is converted into DC energy through 2.4kW power cells. With this study, electrical energy analysis of the clean energy house was carried out. Within the framework of the study, harmonics, voltage changes, voltage and current sags, voltage and current swells, transients, power-cuts, frequency changes, in short, power quality of the whole system was analyzed. © 2010 Praise Worthy Prize S.r.l. - All rights reserved.
