This article proposes an online spatial risk analysis capable of providing an indication of the evolving risk of power systems regions subject to extreme events. A Severity Risk Index (\n                    <jats:italic>SRI<\/jats:italic>\n                    ) with the support of real\u2010time monitoring assesses the impact of the extreme events on the power system resilience, with application to the effect of windstorms on transmission networks. The index considers the spatial and temporal evolution of the extreme event, system operating conditions, and the degraded system performance during the event.\n                    <jats:italic>SRI<\/jats:italic>\n                    is based on probabilistic risk by condensing the probability and impact of possible failure scenarios while the event is spatially moving across a power system. Due to the large number of possible failures during an extreme event, a scenario generation and reduction algorithm is applied in order to reduce the computation time.\n                    <jats:italic>SRI<\/jats:italic>\n                    provides the operator with a probabilistic assessment that could lead to effective resilience\u2010based decisions for risk mitigation. The IEEE 24\u2010bus Reliability Test System has been used to demonstrate the effectiveness of the proposed online risk analysis, which was embedded in a sequential Monte Carlo simulation for capturing the spatiotemporal effects of extreme events and evaluating the effectiveness of the proposed method.\n                  <\/jats:p>","DOI":"10.1111\/risa.13220","type":"journal-article","created":{"date-parts":[[2018,10,23]],"date-time":"2018-10-23T21:30:53Z","timestamp":1540330253000},"page":"195-211","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":65,"title":["Spatial Risk Analysis of Power Systems Resilience During Extreme Events"],"prefix":"10.1111","volume":"39","author":[{"given":"Dimitris N.","family":"Trakas","sequence":"first","affiliation":[{"name":"Electric Energy Systems Laboratory, School of Electrical and Computer Engineering National Technical University of Athens Athens Attiki Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathaios","family":"Panteli","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering University of Manchester Manchester Greater Manchester UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikos D.","family":"Hatziargyriou","sequence":"additional","affiliation":[{"name":"Electric Energy Systems Laboratory, School of Electrical and Computer Engineering National Technical University of Athens Athens Attiki Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierluigi","family":"Mancarella","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering University of Manchester Manchester Greater Manchester UK"},{"name":"Department of Electrical and Electronic Engineering University of Melbourne Parkville Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,10,23]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"crossref","unstructured":"Bhat R. &Meliopoulos A.(2016 March).Probability of distribution network pole failures under extreme weather conditions.
