Exergoeconomic and techno-economic analysis of a solar multi-generation plant with thermal energy storage

摘要

A exergoeconomic and techno-economic analysis of integrating multi-effect distillation, absorptionrnrefrigeration and process heat plants in a concentrated solar power plant is carried out. A solarrnmultigeneration plant is modeled to simultaneously produce electricity, desalinated water, cooling, andrnprocess heat. The methodology considers modeling a multi-generation plant, applying exergoeconomicrnmethod and levelized cost method. The solar multi-generation plant is simulated in a typical meteorologicalrnyear, with one hour time-step and a yearly total DNI of 3,389 kW h/m2/year, considering the demand of arnspecific mining company located in northern Chile. The analysis of simulation shows that the levelized costrnmethod overcharges electricity and undercharges water, cooling and process heat with respect to thernexergoeconomic method. The exergoeconomic method is a robust method of cost allocation for applying in arnsolar multi-generation plant.
