Distributed generation (DG) based on Renewable Energy Sources (RES) has been increased in the last decade and penetrated the energy generation markets due to the huge rising up in energy consumption, environmental issues as well as due to the predicted depletion of the conventional energy sources. DG system uses disbursed generators near load sites, while traditional centralized generation units normally located far away from the loads.
This paper defines and introduces various combinations of DG systems based on RES and storage devices. The suitable application of each combination is addressed.
A case study to electrify a typical household in Italy using standalone hybrid system based on wind energy conversion system (WECS), photovoltaic energy conversion system (PVECS) and battery energy storage system (BESS) is presented to contribute in further understanding of DG systems.
This paper discusses the general issues of the system and introducing the simulation results without going into specific details of modelling and control strategies. The case study depends on real winter weather data collected in CNR/ITAE-Italy/Messina and on a designed winter household profile for Italy.
The simulation results of the case study are discussed. It shows the effectiveness of the proposed DG system in which the power flow among the different energy sources, storage battery energy system and the load demand is balanced successfully.
