Abstract:

The production of electric energy from renewable sources has become inevitable due to economic and environmental importance. One of the important obstacles to increasing the integration of these sources to the electrical grid is their high initial cost. The optimum design of such renewable energy systems is the most powerful solutions to this obstacle. This paper proposes an optimum techno-economic design of a hybrid power model consisting of two renewable sources that are PV and wind, which also fed by the electrical grid. The optimal design aims to find the minimum energy cost per kilowatt by determining the optimal number of components for the hybrid system, whether photovoltaic panels or wind turbines, while achieving continuity of energy production to fulfill the intended consumption. This optimization is performed using the Hybrid Optimization Renewable Energy Model (HOMER) simulation tool. In addition, this paper presents the maximum energy harvesting that can be obtained for the two energy sources used in the system during changes in environmental conditions. This study was simulated using MATLAB / SIMULINK. It was found from the application of the study that the grid/photovoltaic/wind is the most effective assembly of the system with the lowest price of energy was $0.89/Kw, this lowest cost was obtained at the optimal hybrid system with 6 MW and 7.5 MW for PV and wind system respectively. Also, The study revealed that the proposed hybrid system was also more successful with providing stability for both voltage and frequency while obtaining maximum power from the system and the electrical grid.<
