Operation Strategy for a Stand-Alone Hybrid Energy System Supplying a Remote Residential Home for Minimizing Total Cost and Carbon Emission Equipped with Geothermal System

Abstract

This study deals with the operational control strategy of a Hybrid System (HS) for a residential home equipped with a Geothermal System (GS). HS includes photovoltaic (PV), wind turbine (WT), battery energy storage system (BESS), and diesel generator (DG). The thermodynamic module of the GS was used to calculate the value of the electrical energy that could be saved, and the variation in environmental temperature during the day was considered. The presented model was studied using different scenarios for a residential home in Iraq and analyzed in terms of economic and environmental aspects. The results show that during some hours of the day, a GS minimizes the power drawn from the DG, reducing the cost and emissions of the total electrical power generation.
