Abstract
Off-grid hybrid energy systems are attractive options for supplying electricity to rural areas in all aspects like, reliability, sustainability and environmental protection. It is especially best option for communities living far in the interior areas, where grid extension is not appropriate. Ethiopia is also facing the same problem. Many villages are very far from the grid. Therefore, off grid hybrid systems will supply those villages. This work presents the photovoltaic, wind turbine, battery bank and diesel generator based off grid system, which is sized and simulated for the rural community of Addis Border village in the Southern Regional State of Ethiopia. Primary load demand of 142kWh/day, peak load of 26kW, deferrable energy requirement of about 27kWh/day, and deferrable peak load of 3.6kW are involved during modeling of the proposed stand alone power system.
