Natural Gas Short-Term Operation Problem with Dynamics: A Rank Minimization Approach [PDF]
, 2022 Natural gas-fired generation units can hedge against the volatility in the uncertain renewable generation, which may occur during very short periods. It is crucial to utilize models capable of correctly capturing the natural gas network dynamics induced by the volatile demand of gas-fired units.

Dynamic Security Region of Natural Gas Systems in Integrated Electricity-Gas Systems [PDF]
arXiv, 2023 In an integrated electricity-gas system (IEGS), the tight coupling of power and natural gas systems is embodied by frequent changes in gas withdrawal from gas-fired units to provide regulation services for the power system to handle uncertainty, which may in turn endanger the secure operation of the natural gas system and ultimately affect the safety ...

Modeling Gas Flow Directions as State Variables: Does it Provide More Flexibility to Power Systems? [PDF]
arXiv, 2022 As a common practice, the direction of natural gas flow in every pipeline is determined ex-ante for simplification purposes, and treated as a given parameter within the scheduling problem. However, in integrated gas and electric power networks with a large share of intermittent renewable power supply, it is no longer straightforward to optimally ...

Control of Line Pack in Natural Gas System: Balancing Limited Resources under Uncertainty [PDF]
arXiv, 2023 We build and experiment with a realistic but reduced natural gas model of Israel. The system is unusual because (a) it is controlled from a limited number of points which are at, or close to, the gas extraction sites offshore of Israel's Mediterranean coast; (b) control specifies average flux at inlet, not pressure; (c) there are no inland compressors ...

On Negative Correlation of Arboreal Gas on Some Graphs [PDF]
arXiv, 2023 Arboreal Gas is a type of (unrooted) random forest on a graph, where the probability is determined by a parameter $\beta>0$ per edge. This model is essentially equivalent to acyclic Bernoulli bond percolation with a parameter $p=\beta/(1+\beta)$. Additionally, Arboreal Gas can be considered as the limit of the $q$-states random cluster model with $p ...

An Investigation of Natural Gas as a Substitute for Diesel in Heavy Duty Trucks and Associated Considerations [PDF]
arXiv, 2015 In this paper, applicability of natural gas fuel for transportation as compared to diesel is investigated. This study investigates a promising technology for the heavy duty truck sector of transportation as a target for conversion from diesel to natural gas. The supply of natural gas is limited so we also verify the available domestic supply quantities
