Techno-Economic Analysis (Design) of on-grid hybrid power system considering MPPT

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 into the electrical grid is their high initial cost. The optimum design of such renewable energy systems is the most powerful solution 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 are 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 $0.15/Kw, this lowest cost was obtained at the optimal hybrid system with 5.2 MW and 7.5 MW for PV and wind system, respectively. Also, the study revealed that the proposed hybrid system was also more successful in providing stability for both voltage and frequency while obtaining maximum power from the system and the electrical grid.
