Development of a new hybrid energy system based on a microturbine and parabolic trough collector for usage in sports stadiums

The use of solar technologies is expanding day by day due to easy access and its easiness in combining with other systems. The low density of solar radiation in some places has caused a quiet acceptance of this type of energy, which can be overcome by concentrating solar radiation in a specific area. One of the other problems of renewable energy is the lack of access at all hours of the day and night, and to solve this problem, a gas microturbine system has been used. The purpose of this research is to supply the thermal and electrical energy needed by the sports stadium. The purpose of this research is to investigate the hybrid gas microturbine system with a capacity of 30 kW with a linear parabolic concentrator collector. To achieve this goal, thermodynamic modeling was done and the effect of effective parameters on electrical and thermal power production was evaluated. Among the significant results of this research, the decrease of 0.1% in mechanical power due to the increase of 5 °C in the ambient temperature is noticeable, and on the other hand, according to the obtained results, it can be said that the electrical and mechanical efficiencies increase by 3% due to the increase in the annual radiation intensity to the amount of 1100 W/m2.
