The analysis of sensitivity of criterion function for management of heat supply of city areas of systems

The process of heating the modern Ukrainian city must meet the high requirements of reliability and efficiency. Usually the problem of heating and hot water supply are solved centralized by network of regional boiler rooms. At the same time, depreciation of equipment and pipelines increases the thermal and physical loss of coolant, which significantly reduces the efficiency of the heat supply system. This leads to the fact that some consumers is switches to alternative sources of heat such as modular and roof boiler rooms, the individual boilers, heat pumps, etc. Previously been proposed target function for controlling the heat supply system such distributed across the city. The function allows to estimate the unit cost of production thermal energy arbitrary source, given its reliability and efficiency. This paper presents the results of the parametric sensitivity analysis of the proposed target function to deviations of various parameters. It is shown that for heat supply systems with a big network of pipelines major influencing factor is reliability. Maintaining such pipelines in good condition can significantly reduce the cost of primary energy. It is also shown that the heat pump is mainly influenced factor is their thermal conversion factor, and the use of the band in electricity tariffs heat pumps allow receive thermal energy at a very low cost. Formulated recommendations on which options should be improved in the first place to achieve maximum effect.
