Technical-economic evaluation of medium-power gas turbine plant with air bottoming cycle

... and economic analysis. The approach used in the study is aimed at solving two types of optimization problems: (1) to determine the maximum net efficiency of the power plant and (2) to adjust the equipment and operating parameters for achieving minimum costs of electricity production. The study shows that the air bottoming cycle provides an increase in the net efficiency up to 44 - 48% and adds about 20% to the installed power capacity. The minimum costs of electric energy production estimated for different ...

One approach to the study of gas pricing based on gas supply systems modelling (the case of Northeast Asia)

... of gas supply systems. The object of the study is the Northeast Asian gas market. The model of the excessive gas supply system in Northeast Asia is described. The primal problem of the model is to minimize the sum of gas production and transportation costs under the infrastructure constraints. The solutions to the primal problem are the volumes of gas produced in each production point and transported via each route. The solutions to the dual problem (dual variables or shadow prices) are node prices ...

Mathematical Modeling of the Heat Energy Market on a Single Heat Supplier Basis

... are considered. An equilibrium mathematical model is proposed for the liberalized tariff setting conditions based on a microeconomic monopolistic market model. This mathematical model allows for taking into account energy production and transportation costs as part of a single economic criterion and to determine the supply-and-demand equilibrium for heat energy. A regulated heat energy market model on the SHS basis considers an option of a tariff setting for consumers of the housing and utility sector ...

Energy-intensive manufacturing enterprises as active players in demand side management system

... problems in the energy industry is ensuring rational operating conditions of electric power systems under variable loads and with regard to cost-effectiveness and technical capabilities of power plants. Supply fluctuated load considerably increases the costs in the power systems. The price of electricity in the case by changed load is generally higher than by constant load. This price cannot be decreased without cooperation with consumers. The last decade has shown an intensive adoption of new smart ...
