Significant voltage levels can be induced in the gas pipelines due to power transmission lines in the areas where they share the same corridor, especially during a fault. These voltages can affect the operating personnel, pipeline associated equipment, cathodic protection and the pipeline itself. Quite often, mitigation is required to reduce these induced voltages to levels that are safe for pe...

4 We present an optimal control model that captures spatiotemporal interactions between gas 5 and electric transmission networks. We use the model to study flexibility and economic oppor6 tunities provided by coordination. A case study in the Illinois system reveals that coordination 7 enables the delivery of significantly larger amounts of natural gas to the power grid. In particular, 8 under ...

Title of dissertation: A STOCHASTIC EQUILIBRIUM MODEL FOR THE NORTH AMERICAN NATURAL GAS MARKET Jifang Zhuang, Doctor of Philosophy, 2005 Dissertation directed by: Professor Steven A. Gabriel Department of Civil and Environmental Engineering This dissertation is an endeavor in the field of energy modeling for the North American natural gas market using a mixed complementarity formulation combin...

This paper presents a game-theoretic analysis of multimarket competition with capacity investments, applied to international gas markets. It identifies a strategic advantage of «focused» pipeline gas producers (e.g., Gazprom) over «diversified» multimarket exporters of liquefied natural gas (e.g., Qatar). Based on this, the paper examines the spillover impacts of the Fukushima nuclear accident ...

This study mainly focuses on enhancing the overall efficiency of gas transmission networks. The authors developed a model with detailed characteristics of compressor and pressure reduction stations. Following this, they suggested three different systems with gas turbine including: organic rankine cycle (ORC), air bottoming cycle (ABC), and ABC along with steam injection (SI-ABC). In addition, u...

Abstract At present, volume measurement is still used in transfer of natural gas China, so the calculation and management Unaccounted for Gas are based on measurement. With change method from to energy measurement, will be paid more attention. This paper investigates methods measures China other countries, compares research progress. The results show that: general principles countries basically...

The pipelines in mountainous areas have complex terrain conditions and pass through many densely populated areas. Once a pipeline leakage accident occurs, it will cause serious damage to the surrounding people environment. In this article, diffusion model of bare natural gas is established for exposed scenario, simulation scheme according characteristics pipeline-laying processes environmental ...

Worldwide consumption in oil and natural gas is expected to lead all other energy sources in the next 20 years. The oil & gas pipeline network will constantly expand placing greater demand on operators to ensure any integrity threats to these pipeline systems are accurately and reliably identified. What are the main integrity threats to pipelines? There are many such as third-party damage, exte...
