Comparative Cost Analysis for Sizing of Different Stand Alone and Hybrid Energy Systems

Emad Ahmed Sweelem

Renewable energy stand-alone and hybrid energy system are promised the attractive solution to generate the electricity for rural and remote area. But, the only disadvantage to use it, it’s energy cost ($/kWh). In this paper, a formulation for optimizing the design of different kind of stand-alone and hybrid energy system are developed. This formulation employs linear programming techniques to minimize the average production cost of electricity while meeting the bad requirements in a reliable manner. The computer program (HOMER) developed reads the necessary input data, formulates the optimization problem by computing the coefficients of the objective function and the constraints and provides the optimum wind, solar, diesel, and battery ratings. In order to study the effect of parameters predefined by the designer on the optimum design, several sensitivity analysis studies are performed, and the effects of the expected energy not served, the bad level, the maximum available wind area, the maximum available solar areas, and the diesel engines‘ lifetime are investigated. Finally, the results show the comparison between the different kind of renewable energy systems with and without diesel. Also, the best system which gives us the minimum energy production cost and the maximum output energy.
