Optimal life cycle oriented design of a GT + 1PSH HRSG type CCGT power plant.

Abstract

In the present work, a life cycle oriented approach is used for designing power plants in a way they can satisfy the desired demand along the whole time horizon, while a selected performance indicator of the project is optimized. As case study, optimal design characteristics as well as optimal values of long term operation parameters of a GT + 1PSH HRSG Type CCGT power plant (GT: gas turbine, 1PSH HRSG: 1 pressure with superheater-heat recovery steam generator, CCGT: combined cycle gas turbine) are obtained by means of a multiperiod mathematical model, seeing that the selected performance indicator is maximized. In addition, advantages of the life cycle oriented approach results are discussed when compared with a power plant design obtained by traditional methods.
