In order to establish better performance compromises between the process functionals of a heat engine, in the context of finite-time thermodynamics (FTT), we propose some generalizations for the well-known Efficient Power function through certain variables called “Generalization Parameters”. These generalization proposals show advantages in the characterization of operation modes for an endoreversible heat engine model. In particular, we introduce the k-Efficient Power regime. For this objective function we find the performance of the operation of some power plants through the parameter k . Likewise, for plants that operate in a low-efficiency zone, within a configuration space, the k parameter allows us to generate conditions for these plants to operate inside of a high-efficiency and low-dissipation zone.
