Introduction

The major target of this paper shows effect of selected decision variables in the steam system for optimization of thermal combined cycle power plant.
Material and

Method

Exergoeconomic, and other similar terms used to imply the combined thermodynamic and economic analysis of energy systems, which helps to increase the efficiency of a plant without jeopardizing its economic viability. The optimization accomplished using an iterative exergoeconomic. The design data of an existing plant (Damavand combined cycle power plant in Tehran) used for the present analysis.
Results and Diction: Two different objective functions proposed: one minimizes the total cost of production per unit of output, and the other maximizes the total exergetic efficiency. The analysis shows that the total cost of production per unit of output is 2% lower and exergy efficiency is 4% higher with respect to the base case. It demonstrates that selected decision variables have a good result for the exergy analysis and cost effectiveness
