Maksymov M. Improving the energy efficiency of biogas technology via searching for the best structure of its power plants by computer-integrated control system.

The dissertation is devoted to the improvement of methods and models of automated control of a biotank power plant, which uses renewable energy sources to maintain the balance of the energy system. The aim of the dissertation is to improve the methods and models of computer-integrated control system of a power plant that uses renewable energy sources to maintain the balance of the power system by finding the best structure of its components, and move such plants to a regulated class with energy efficiency increasing. The following issues are solved in the dissertation. A method of express analysis has been developed, which determines the suitability of power plants of different types, depending on their dynamic characteristics, for the possibility of compensating for disturbances in the power system. Simulation models of biogas technology as a control object have been created to increase its efficiency, which allowed to obtain additional energy resources. Models of the automated control system and the method of controlled pyrolysis for utilization of the fermented residue of variable composition have been investigated, obtained in biogas technology, which allows to produce additional synthesis gas with maximum calorific value, A method for determining the objective optimization function and finding the best structural combinations of the power plant using renewable energy sources, which have the possibility of regulation, depending on external disturbances in order to maintain the balance of the power system.
