The interaction of the gas network with the electrical grid is modeled through mathematical equations that represent the energy exchange between the two infrastructures. The joint natural gas and power flow is solved using the linear-analog transformation (LAT) and the Newton-Raphson (NR) algorithm, respectively. Here, a unified solution framework of the two systems is presented using the previous proposed methods. The applicability of the methodology is illustrated using two case studies: IEEE-14 bus test system combined with a 16-node natural gas network and the IEEE-30 bus test system integrated with a 15-node natural gas network with 4 compressors. The proposed methodology proves to be useful for the assessment of coupled natural gas and electricity critical infrastructures. info:eu-repo/grantAgreement/ES/MINECO/ENE2016-77172-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.211 2019 1.042 2019 ENGINEERING, ELECTRICAL & ELECTRONIC 78 / 266 = 0.293 2019 Q2 T1 Energy Engineering and Power Technology 2019 Q1 Electrical and Electronic Engineering 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-4770-0069 Dominguez Navarro, Jose Antonio Universidad de Zaragoza (orcid)0000-0003-3174-9703 Yusta Loyo, Jose Maria Universidad de Zaragoza 5009 535 Universidad de Zaragoza Dpto.
