Transient simulation of a solar-PV/battery-based electricity and cold supply for an off-grid restaurant under the climatic conditions of Doha city

This project considers a solar power and battery system to provide the electricity and cooling of food and fast-food restaurants which is off-grid. This off-grid restaurant is designed to be considered for the world cup 2022 which will be held in Qatar, and it has been modeled in Open Studio software with renewable energy. The system uses solar energy as renewable energy and to store the surplus electricity; battery banks are considered for nights. TRNSYS software with the ability of transient simulation of renewable energy systems is used. This research has been simulated using weather data from Doha in Qatar with its high solar radiation transiently at all hours of the year. The results showed that photovoltaic panels in Doha, Qatar, with their high solar radiation can provide 56% of the annual energy for the off-grid restaurant without batteries. Using batteries alongside these panels could reduce the grid dependency down to 9% per year, which could be provided using diesel-based generators due to being low. Furthermore, batteries could create complete grid independence for the off-grid in some months. The usage of batteries in solar panel systems considerably reduces the Conex box grid dependency. They provide 35% of the annual Conex box power consumption rate based on results from this modeling. This research provides significant results and impacts for the upcoming world cup where a lot of people from various countries will go to Qatar and off-grid restaurants in addition to reducing the emission can also highlight the importance of using renewable energy for future sustainability.

Automated summary

This project considers the use of solar power and battery systems to provide electricity and cooling for off-grid restaurants. The research demonstrates that photovoltaic panels can meet a significant portion of the energy needs for off-grid restaurants, with the use of batteries further reducing dependency on the grid. These findings are important for the upcoming World Cup in Qatar, as they highlight the significance of using renewable energy and can serve as a model for future sustainability.
