Despite the availability of new alternative energy sources, growing worldwide energy demand and emissions targets lead power plants to work optimizing performances. In this new scenario in which renewable energies are increasingly taking the field, it is also important to produce energy at a low price. Moreover, the variability of the energy market price complicates the analysis. Comparison between the produced energy cost and the market price is necessary to get a return on investment. In this context, the paper investigates the implications of using a gas turbine in an energy system estimating the plant layout and the number of working hours that guarantees a better profit. The analysis focuses on the study of the start-up and shutdown operation mode to find the optimal solution strategy in the Italian electricity market.

The optimization of the steam parameters of the heat recovery steam generators (HRSG) of Combined Cycle Gas Turbines (CCGT) has become one of the important means to reduce the power generation cost of combined cycle units. Based on the structural theory of thermoeconomics, a thermoeconomic optimization model for a triple pressure reheat HRSG is established. Taking the minimization of the power generation cost of the combined cycle system as the optimization objective, an optimization algorithm based on three factors and six levels of orthogonal experimental samples to determine the optimal solution for the high, intermediate and low pressure steam pressures under different gas turbine (GT) operation strategies. The variation law and influencing factors of the system power generation cost with the steam pressure level under all operation strategies are analyzed. The research results show that the system power generation cost decreases as the GT load rate increases, T4 plays a dominant role in the selection of the optimal pressure level for high pressure (HP) steam and, in order to obtain the optimum power generation cost, the IGV T3-650-F mode should be adopted to keep the T4 at a high level under different GT load rates.

Energy, economy, and ecological (3E)-based analysis of steam cycle power plant evaluated through multiobjective investigation. The Montazer Ghaem steambased power plant situated in Iran is considered for investigation. Cycle efficiency, total cost, and ecological function of steam power cycle are treated as the 3E objective in the analysis. Simultaneous optimization of this performance parameter is executed through a heat transfer search algorithm. Fifteen operating variables of the steam power cycle, which includes different pressure, temperature, and isentropic efficiency are
