Technical criteria, environmental criteria, economical criteria as well as reliability parameters are used to evaluate the impact of the planned transmission line alternatives. For the reliability evaluation a minimal cut-set-algorithm has been implemented, tested and validated with the NEPLANreg reliability tool. The resulting Multi-Criteria Decision Making problem (MCDM), which is solved by a genetic algorithm (GA) in this paper, is to build a reliable transmission grid with low environmental impact on the public sector, minimum on unavailability and with minimal life-time-costs. The results of the optimization process on an example grid are discussed and further improvements are listed.","PeriodicalId":429968,"journal":{"name":"2008 Power Quality and Supply Reliability Conference","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134386979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
