Replacing clean and renewable energy with energy from fossil fuels is critical today, and more efficient energy systems and more efficient use of renewable resources are needed to sustain energy systems in the future. In multiple power generation systems, proper selection of energy supply sources is one of the most important issues. Solar energy, which according to the potential of the implementation site, which is the implementation site of this project in Khuzestan province, was determined as a suitable source to provide the necessary energy for the system studied in this dissertation. In the present study, we investigated a renewable system and the use of solar energy with suitable and close to reasonable conditions with high solar potential. The main components of the system consist of a solar tower system, a heat storage source, a Brighton cycle, a steam Rankin cycle, Reverse Osmosis and a single-effect absorption refrigeration cycle. The main outputs of this system include fresh water, generated electricity and cooling. These systems are a receiver system where heat is transferred to the mirrors and hot air is given to the turbine and then the power generation process is performed. Fresh water produces cooling absorption through RO desalination and chiller. In this system, there is a Brighton cycle that uses a solar system instead of a combustion chamber, which is an innovation. EES software has been used as an engineering tool to model the system and obtain thermodynamic results.The city of Ahvaz was analyzed by examining the potential of solar radiation as a case study. The most important effective and practical parameters in these studies are solar intensity (DNI), number of heliostat (N_hel), turbine inlet pressure (P8) and compressor pressure ratio (r_p).
Keywords: Solar energy, Multiple energy production system, Multi-objective optimization, Exergy, Cost rate.
