Hydrogen is of great significance for replacing fossil fuels and reducing carbon dioxide emissions. The application hydrogen mixing with natural gas in network transportation not only improves the utilization rate energy, but also reduces cost large-scale updating household or commercial appliance. This paper investigates necessity a device adding to existing pipelines industrial network. A thr...

The main aim of this study is to identify the most important natural gas pipeline failure causes and interrelation analysis. In research, rough analytic hierarchy process (Rough-AHP) used rank order. Then a combination decision-making trial evaluation laboratory (DEMATEL) interpretive structural modeling (ISM) method applied generate level importance. comparison traditional DEMATEL Rough-DEMATE...

In this study, the energy consumption in the food and beverage industries of Iran was investigated. The energy consumption in this sector was modeled using artificial neural network (ANN), response surface methodology (RSM) and genetic algorithm (GA). First, the input data to the model were calculated according to the statistical source, balance-sheets and the method proposed in this paper. It ...

In this paper, the combined natural gas and electric optimal power flow (GEOPF) is presented. It shows fundamental modeling of the natural gas network to be used for the GEOPF, and describes the equality constraints which describe the energy transformation between gas and electric networks at combined nodes (i.e., generators). We also present the formulation of the natural gas loadflow problem,...
