The optimal control of the process of energy production is the cheapest way of increasing its thermal efficiency. However, the possible benefits could be achieved both by setting optimal values of thermodynamic parameters as well as by decreasing the time span of change of these values, dependent upon change of cogeneration plant energy load. Computer-aided modelling and optimisation applied to these two aspects of steering can be done with use of accessible computer software and should lead to economical profits through the thermal cycle efficiency increase. A new methodology of optimal thermal cycle steering is presented in this paper. This methodology is based on local data models formulated owing to data obtained from the simulation software. Optimisation procedures are applied to found the best values of thermodynamic parameters of the thermal cycle which realise one of the important steering aspects. Moreover, because of using simulation software the calculations are fast enough to realise also the second one. This paper also presents application of methodology and evaluated numerical procedures to optimisation of thermal cycle of cogeneration power plant for which the simulation model was also elaborated. Optimisation process was made for different thermodynamic parameters with respect to total egzergetic and energetic efficiency of the cycle.
