The famous economic, exergic, thermoeconomic optimization methods do not take into account the changing of heat accumulation capacity of power systems. This complicates the coordination of the production and energy consumption and requires additional equipment. It was suggested to evaluate the changing of heat accumulation capacity on the basis of the information as a measure of reflection ratio of energy production and consumption in a single information space. This makes it possible to predict the change of the parameters of the technological process and not to eliminate the effects of their changes. Methodological and mathematical explanations of expert systems architecture were developed, using coordinated interaction of dynamic subsystem. Dynamic subsystem is the energy system as the base and units that predict the main stages of the technological process. The methodology of the mathematical formulation of the dynamics of power systems was worked out. The change of parameters is presented in both time and space coordinate along the axis of the heat exchanger, which coincides with the direction of flow. The graph of cause-and-effect relations was designed, to control operability and to identify the state of power systems. The thermodynamic basis of admission, as the structure and the principle of intelligent control of heat-mass exchanging processes, was formulated. The examples of the developed technologies and assessment of their effectiveness were represented.References
