As a result, short-circuit current is not constant, but it varies depending on the current and disconnection order of distributed generators (DGs). This time-varying short-circuit current complicates the estimation of the time it will take for an overcurrent relay or fuse to trip. The existing short-circuit calculation algorithms usually assume that the fault current is constant throughout the whole period of fault. This assumption may result in incorrect conclusions regarding the tripping time of protective devices in networks with high renewable penetration. This paper incorporates modern FRT standards into the fault analysis by considering the influence of fault current variations on the protective devices (relays, fuses), significantly increasing the accuracy of the estimated tripping time. Simulations carried out in a 13-bus and the IEEE 8500-node network indicate that the traditional short-circuit calculation approaches may miscalculate the tripping time of protective devices, with deviations up to 80 s, when applied to networks complying with modern FRT standards.<\/jats:p>","DOI":"10.3390\/s23218868","type":"journal-article","created":{"date-parts":[[2023,10,31]],"date-time":"2023-10-31T12:53:32Z","timestamp":1698756812000},"page":"8868","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Incorporating Modern Fault Ride-Through Standards into the Short-Circuit Calculation of Distribution Networks"],"prefix":"10.3390","volume":"23","author":[{"given":"Evangelos E.","family":"Pompodakis","sequence":"first","affiliation":[{"name":"Institute of Energy, Environment and Climatic Change, Hellenic Mediterranean University, 71004 Heraklion, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1994-4314","authenticated-orcid":false,"given":"Yiannis","family":"Katsigiannis","sequence":"additional","affiliation":[{"name":"School of Engineering, Power Systems and Energy Engineering, Hellenic Mediterranean University, 71004 Heraklion, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3589-0627","authenticated-orcid":false,"given":"Emmanuel S.","family":"Karapidakis","sequence":"additional","affiliation":[{"name":"School of Engineering, Power Systems and Energy Engineering, Hellenic Mediterranean University, 71004 Heraklion, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"300","DOI":"10.35833\/MPCE.2021.000542","article-title":"Distribution Management Systems for Smart Grid: Architecture, Work Flows, and Interoperability","volume":"10","author":"Jabr","year":"2022","journal-title":"J.
