Management of city heat supply of system due to target optimization of structure of technical means

The process of heat supply a modern Ukrainian city actually provides a variety of different sources of thermal energy, both at the local level, individual consumers, and at the level of separate houses, neighborhoods and entire district. Today the market of thermal power equipment offers a wide range of thermal energy sources: district and industrial boilers and CHP, roof, modular boilers, heat pumps, boilers operating on different fuels, electric water heaters, oil heaters, etc. For several reasons, today the final consumer solves the problem of heating due to various alternative sources of thermal energy, which can operate simultaneously and in parallel. Given the progressive and payment multiband primary energy cost per unit of heat energy for individual consumer may vary significantly depending on the source. In this paper we propose a modified objective function, which allows you to estimate the cost of thermal energy source without actually turning. Raised a number of model experiments and the results of their analysis. It is shown that in the presence of alternative sources of heat energy of different physical nature and effectiveness of the possible solution of the optimization process in order to minimize heating costs. In addition, the proposed approach can also be used as a means of diagnosing the state of thermal networks to increase the cost of thermal energy.
