Elimination of Undetectable Attacks on Natural Gas Networks

IEEE Signal Processing Letters, 2021
Natural gas pipeline system operations rely heavily on Supervisory Control and Data Acquisition (SCADA) systems. While the SCADA systems introduce many advantages, they also introduce more vulnerabilities by providing opportunities for malicious cyber-attackers.

Forecasting Natural Gas Flows in Large Networks

2017
Natural gas is the cleanest fossil fuel since it emits the lowest amount of other remains after being burned. Over the years, natural gas usage has increased significantly. Accurate forecasting is crucial for maintaining gas supplies, transportation and network stability.

Fundamentals of Natural Gas Networks

2019
Natural gas is a fossil fuel that was formed over millions of years from decomposing organic matter, which was subject to intense heat and pressure as successive layers of sand and rock were laid down. It is a mixture of hydrocarbon and non-hydrocarbon gases and is usually found in porous material underneath an impervious rock layer that prevents the ...

Natural gas distribution network modelling and leak minimization

Proceedings of the 11th IEEE International Conference on Networking, Sensing and Control, 2014
A gas network model has been constructed based on the steady-state Weymouth equation. A fast and robust solution algorithm is proposed and subsequently used to calculate all flows and pressures in a gas network with over 40,000 pipes. The obtained result is mathematically accurate within 0.1% and has been obtained within 0.2 seconds.

SERVICEABILITY OF NATURAL GAS DISTRIBUTION NETWORKS AFTER EARTHQUAKES

Journal of Earthquake and Tsunami, 2013
The concept of disaster resilience has received considerable attention in recent years and it is increasingly used as an approach for understanding the dynamics of natural disaster systems. No models are available in literature to measure the performance of natural gas network, therefore, in this paper, a new performance index measuring functionality ...

Topology Attack Detection in Natural Gas Delivery Networks

2019 53rd Annual Conference on Information Sciences and Systems (CISS), 2019
Whenever a system operator is led to believe that the system topology is different from the actual system topology, we call this a topology attack. These attacks can cause tremendous damage from the result of improper network control. A number of algorithms to detect these attacks for electrical networks have been suggested in the literature, but such ...
