Formulation of the objective function for economic dispatch optimisation of steam cycle CHP plants

Abstract

The paper starts the series of publications concerned on production simulation and expansion planning of various cogeneration applications, especially based on distributed generation technologies. This particular paper presents the formulation of optimisation problem for economic dispatch of steam cycle CHP plants widely used in the former Soviet Union. Polynomial quadratic equations were applied to describe interrelations between input steam and output power and heat for cogeneration steam turbines. Mathematical model of turbines was verified by numerical example, taking the input data from normative characteristic graphs.
