A system of mathematical models for studying the prospects of functioning and development of gas industry under current conditions
Journal Title: Проблеми загальної енергетики - Year 2017, Vol 0, Issue 3
Abstract
To study the prospects of development of the gas industry, we propose a system of mathematical models that takes into account the considerable uncertainties of external and internal conditions of its operation, the life time of main technological equipment, and constraints on investment resources. The optimization mathematical model of development of the gas industry is implemented in the modeling language MathProg, which enables one to describe the logic of mathematical model fairly transparently by using binary variables, which is quite problematic in the application of other optimizers. It is established that the use of GLPK optimizer enables one to solve large-scale problems with binary variables, which include the task of forecasting the functioning and development of gas industry within an acceptable time framework.

Enhancement of the efficiency of burning low-reaction coal in the swirl burners of boilers at their high-concentration dust supply under pressure
We describe the results of investigating the work of swirl burners of TPP-210A boiler of a 300 MW power unit at traditional and high-concentration systems of dust supply and the influence of these technologies on the eff...
Influence of the nonuniformity of water-concentration distribution in a tower scrubber on the efficiency of the cleaning of flue gases from solid particles
Enhancing the efficiency of the cleaning of flue gases of pulverized-coal fired boilers from fly ash is an important ecological problem. In power engineering, apparatus for the wet cleaning of flue gases are widely sprea...
Development of renewable energy using accumulative technologies
A mathematical model for determining the cost of Electric energy supply by different types of storage systems is proposed. This is relevant in accordance with the goal No. 7 – "to ensure stability and reliability of fina...
Revision of the possibilities of the models of equilibrium prices and outputs in the theory of intersectoral balance
Based on the performed analysis of numerous publications containing the models of equilibrium prices and outputs in the theory of intersectoral balance, we have proved that the use of transposed matrices of direct cost i...
Projected demand for fuel and energy resources in the fabrication of some types of energy-intensive chemical products
We give a review of the state of some energy-intensive productions of chemical industry, namely, of ammonia, nitrogen fertilizers, and caustic soda. We also collected and verified initial data on production volumes and c...
