Résumé
Kingdom of Saudi Arabia government has established several projects in line with Vision 2030 to increase the utilization of renewable energy (RE) resources while reducing the environmental impact of oil and gas conventional resources. In the present work, RE systems are considered for electricity and hydrogen productions via hybrid solar and wind systems under local weather conditions. In this case, techno-economic and environmental studies are carried out and MATLAB computer codes are developed to assess the performance of case studies incorporating solar/wind RE systems for different applications. In the first case study, a standalone hybrid PV/wind with battery storage system is devleoped to meet the electrical load requirements of a residential house integrated with electric vehicle under different weather conditions at different locations in the Kingdom of Saudi Arabia, namely : Dammam, Riyadh, Jeddah, Buraydah, Tabouk and Sharurah. The results show considerable variations in the optimum system configurations at the considered locations due to different renewable energy potentials. In the second case study, a hybrid solar/wind system is developed for multigeneration of electricity and hydrogen to meet demands of residential house integrated with hydrogen veicle. In this case study, to assess the performance of the hydrogen production, novel performance indicators are introduced, which include : deficiency in hydrogen supply, and loss of hydrogen supply probability (LHSP). This work is extended to assess the feasibility of indtroducing hydrogen refueling stations in the Kingdom of Saudi Arabia. As hydrogen refueling demand differs in various areas based on people behaviour, a third case study is conducted in the kingdom to evaluate the effect of people behaviour in various areas on the optimization results of hydrogen refueling station. Refueling data is collected in four areas : Industrial, Residential, Highway and Tourist area. Then, the performance of hydrogen refueling station powered by hybrid solar/wind renewable energy system is simulated via MATLAB software. The findings of this study show that, cheapest investment costs are found in the industrial areas. This effect of people behaviour on the optimization results has led to a novel idea of load coordination with solar potential. Therefore, a forth case study is conducted to determine how load coordination with solar energy potential influences the system size and cost in off-grid renewable energy systems. A standalone photovoltaics PV array with battery storage system is considered and optimal size of the system is investigated under various types of load requirements with different load coordination levels with the solar energy availability, namely : street lighting, industrial, residential, and irrigation loads. The findings show that, fully coordinated load (irrigation) resulted in a remarkable reduction in the levelized cost of energy, which was reduced by 24%, while the storage system size was reduced by 39%. On the other hand, with no coordination opportunity for the street-lighting load has been identified, thus no reduction has been obtained.
