Abstract

In this study, Given the importance of Bandar Abbas steam power plant in terms of Location and its electricity generating, it has been considered for applying the repowering method. After reference cycle modeling and assessing results accuracy, the applied repowering method has been implemented and it’s results reported in four main scenarios. Exergy efficiency and electricity generation cost (per kWh) have been considered as objective functions. Based on the six independent variables and four different scenario multi objective optimization has been done. The final reported results can be implemented by the energy managements for making the best decision and choosing the adequate option. Multi objective optimization of proposed combined cycles with single and double pressure heat recovery boilers indicate that the exergy efficiency upgrades up to 46%.
