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

Abstract

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.

Experimental investigation and thermodynamic analysis of application of hybrid nanofluid in a parabolic solar trough collector

“…[1][2][3][4] Solar energy has been identified as the most abundant source of energy, [5][6][7] and it has been estimated that the amount of solar energy entering the earth for 1 h is more than the annual energy consumption of world societies. [8][9][10][11] Currently, solar energy provides part of the energy needed by advanced countries in two forms: electrical energy through photovoltaic systems and thermal energy using solar collectors. [12][13][14] Among the types of solar systems technology, the linear parabolic collector has been widely accepted due to the fact that it can produce high temperatures for heating and cooling, , it needs less space to reflect sunlight in the focal area, and various ways have been proposed to increase the efficiency of this technology.…”
