Therefore, the pre-position and reconfiguration of the microgrid defense resources by means of Mobile Energy Storage Vehicles (MEVs) and tie lines in damaged scenarios have attracted more and more attention. This paper proposes a novel two-stage optimization model with the consideration of MEVs and tie lines to minimize the shed loads and the outage duration of loads according to their proportional priorities. In the first stage, tie lines addition and MEVs pre-position are decided prior to a natural disaster; in the second stage, the switches of tie lines and original lines are operated and MEVs are allocated from staging locations to allocation nodes according to the specific damaged scenarios after the natural disaster strikes. The proposed load restoration method exploits the benefits of MEVs and ties lines by microgrid formation to pick up more critical loads. The progressive hedging algorithm is employed to solve the proposed scenario-based two-stage stochastic optimization problem. Finally, the effectiveness and superiority of the proposed model and applied algorithm are validated on an IEEE 33-bus test case.<\/jats:p>","DOI":"10.3390\/s22166046","type":"journal-article","created":{"date-parts":[[2022,8,15]],"date-time":"2022-08-15T23:44:03Z","timestamp":1660607043000},"page":"6046","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Two-Stage Stochastic Optimization for the Pre-Position and Reconfiguration of Microgrid Defense Resources against Natural Disasters"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9650-4080","authenticated-orcid":false,"given":"Bo","family":"Jiang","sequence":"first","affiliation":[{"name":"College of Systems Engineering, National University of Defense Technology, Changsha 410073, China"},{"name":"Hunan Key Laboratory of Multi-Energy System Intelligent Interconnection Technology, Changsha 410073, China"}]},{"given":"Hongtao","family":"Lei","sequence":"additional","affiliation":[{"name":"College of Systems Engineering, National University of Defense Technology, Changsha 410073, China"},{"name":"Hunan Key Laboratory of Multi-Energy System Intelligent Interconnection Technology, Changsha 410073, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4703-9020","authenticated-orcid":false,"given":"Shengjun","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Systems Engineering, National University of Defense Technology, Changsha 410073, China"},{"name":"Hunan Key Laboratory of Multi-Energy System Intelligent Interconnection Technology, Changsha 410073, China"}]},{"given":"Wenhua","family":"Li","sequence":"additional","affiliation":[{"name":"College of Systems Engineering, National University of Defense Technology, Changsha 410073, China"},{"name":"Hunan Key Laboratory of Multi-Energy System Intelligent Interconnection Technology, Changsha 410073, China"}]},{"given":"Peng","family":"Jiao","sequence":"additional","affiliation":[{"name":"College of Systems Engineering, National University of Defense Technology, Changsha 410073, China"},{"name":"Hunan Key Laboratory of Multi-Energy System Intelligent Interconnection Technology, Changsha 410073, China"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,12]]},"reference":[{"key":"ref_1","first-page":"52","article-title":"Comprehensive assessment of extreme ice disaster affecting power system operation","volume":"31","author":"Zhang","year":"2011","journal-title":"Proc.
