The methodology, developed by the authors, allows to characterize network sites by time series of voltage sags, described by amplitude, duration and type. A responsibility sharing curve is used to establish an adequate voltage sag index. The developed methodology is based on Monte Carlo simulation and considers the stochastic nature of power system faults, as well as the probabilistic nature of successful operation of transmission line and busbar primary protection systems. An application example is presented, considering the IEEE Reliability Test System. The sensitivity of the voltage sag index with regard to the transmission lines failure rate is assessed. Results allow to establish a linear dependence, which is used for site characterization, showing that the methodology is an important tool for network planning, design, operation and maintenance. It allows to quantify the benefits obtained, at each network site, from reducing the transmission lines failure rate.","PeriodicalId":232908,"journal":{"name":"Power Systems Computation Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122874112","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}

To circumvent the combinatorial explosion of reinforcement alternatives, a constructive heuristic algorithm is used for adding new branches to the sub-transmission grid. Based on performance indices to measure the attractiveness of new branches and using an expansion tree, the proposed algorithm is able to capture the combined effect of reinforcement additions. For selecting the best alternative, from the set of good reinforcement solutions, the planned network performance in meeting the future load demand is evaluated, considering the following operational aspects: ohmic losses, reliability, branch loading condition, and voltage profile. The evaluation of the performance indices and all operational aspects is achieved by applying a non-linear AC model-based power flow. For the reliability assessment, an enumeration technique is used to select system states. A large sub-transmission Brazilian system belonging to CEMIG utility is used to validate the methodology and the results are presented and extensively discussed.","PeriodicalId":232908,"journal":{"name":"Power Systems Computation Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126025279","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}
