abstract = "Installing solar collectors to preheat boiler
feedwater is one of the most economical methods of
repowering steam power plants. The production of
freshwater in repowered plants can increase their
productivity. The present study aimed at integrating
the Bandar Abbas steam power plant's repowered cycles
with desalination units and subsequently analyzing the
cycles using the R-Curve tool. Three scenarios are were
considered for repowering: In the first scenario,
parallel collectors were used instead of the
low-pressure feedwater heaters, while in the second and
third scenarios, parallel solar collectors were used
instead of low-pressure feedwater heaters integrated
with multi-effect and multi-stage flash desalination
units, respectively. The dynamic development of the
R-Curve, as well as the use of a combination of
artificial intelligence and genetic algorithm
programming to optimize the complex cycles of the
multi-generation of power, heat, and freshwater, are
the most important issues presented in this study.
Results show that the Bandar Abbas steam power plant in
operation has an R-ratio equal to 1.21 and a
cogeneration efficiency of 36.5 percent. In the first
scenario of repowering, the R-ratio is equal to 1.21,
and in most months, the cogeneration efficiency varies
between 35 and 45 percent. In the second and third
scenarios, however, cogeneration efficiency is 50
percent at its lowest level. Moreover, with the
introduction of the new conceptual graphical curves, it
was found that using more solar energy and adding
desalination units increase the cogeneration efficiency
throughout the year. Optimization of repowered cycles
integrated with multi-effect and multi-stage flash
desalination units increased freshwater production by
178 and 42 percent, respectively",
