The estimation of the country's total needs in primary energy resources and the required volumes of gas to fully cover these needs (taking into account the capabilities of other energy systems of the fuel and energy complex) is made. The total possible levels of Russian gas exports for the future are estimated. The possibilities of fuel and energy complex industries for the perspective satisfaction of the needs of domestic and ...

Mathematical models of elements and mini-CHP in general based on technological schemes were constructed. The mathematical models were constructed with the software developed at Melentiev Energy Systems Institute of Siberian Branch of the Russian Academy of Sciences. The calculations were made for two sizes of internal combustion engines. Thus, we obtained the values of flow rates, temperatures of heat carriers at various points of flow ...

This approach involves the use of a hierarchical system of models, presupposes a preliminary choice of critical objects for energy systems. The approach is focused on the analysis and evaluation of interrelated systems functioning when implementing threats to energy security (in the form of contingencies), requires the accounting for changes in the work of critical objects ...
