英文摘要	Feasibility and optimal sizing analysis have been paid more attention for electrifying rural and remote areas while desert areas have received less consideration. These analyses help in developing effective financial strategies. Therefore, this paper proposes an economic off-grid hybrid AC/DC microgrid design that integrates the AC and DC components including batteries, diesel generators, wind turbines, and photovoltaic arrays to meet the power requirements of 200 kWh/day in the desert region in EI Kharga Oasis, Egypt. The developed system evaluates the cost of electricity, renewable fraction, and loss of power system probability through HOMER Pro simulation by assessing the feasibility and determining the optimal size. The outcomes results are then compared with five configurations of microgrid systems, which include the solar/batteries/converter, wind/batteries/ converter, solar/wind/batteries/converter, solar/wind/ diesel generators/batteries/converter, and standalone diesel generator. As compared to other alternatives, the simulation demonstrates that the solar, wind, diesel generators, batteries, and converter system performs optimally for achieving load demand. In the selected desert region, the optimal solution comprises of 21 kW of solar PV, 15 kW of diesel generators, 20 kW of wind turbines, and 76 kW of batteries. The designed system acquires the lowest net present cost at $103,43 and a cost of energy of 0.10 $/kWh with a high renewable fraction of 90.1 %. Furthermore, considered microgrid generate 7.8 % of CO2 emissions as compared to stand-alone diesel generators. In addition, sensitivity analysis indicates that solar radiation, diesel fuel price wind speed, and rate of interest have a significant impact on the system costs.
