Energy, due to its increasing usage in various broad areas has been maintained as a vital factor in economic growth and development of societies. Meanwhile, natural gas is considered as one of the most important energy sources. Therefore, the efficiency and the productivity of the gas companies are crucial to be assessed. Numerous examples from industrial multistage processes including internal...

We consider balanced flows in a natural gas transmission network and discuss computationally hard problems such as establishing if solution of the underlying nonlinear gas flow equations exists, if it is unique, and finding the solution. Particular topologies, e.g. trees, are known to be easy to solve based on a variational description of the gas flow equations, but these approaches do not gene...

In this study a pseudo comprehensive carbon footprint model for fossil fuel power plants is presented. Parameters which their effects are considered in this study include: plant type, fuel type, fuel transmission type, internal consumption of the plant, degradation, site ambient condition, transmission and distribution losses. Investigating internal consumption, degradation and site ambient con...

ABARE project 1653 Natural gas demand forecasts are used by regulatory bodies when setting transmission and distribution tariffs. Reviews of current forecasting methodology used by gas companies indicate that the current approaches may be inappropriate for forecasting gas demand. The modeling methodology for gas demand forecasting and the implications of the results for the regulation of transm...

The global energy crisis, rising demand and climate warming make it imperative to find ways recover that is not being put beneficial use, reduce primary final consumption, emissions. An important part of Lithuania’s sector the natural gas its transmission network, including distribution stations (GDS). It GDS has an unexploited potential for recovery, as pressure reduced through use regulators,...

This paper intends to take power system planning as the main module, while considering requirements and constraints of natural gas network transportation construction use energy hub model analyse transmission transformation relationship between different networks, realize system, network, transportation. Integrated for network. To verify effectiveness proposed PMIES method, an improved Garver t...
