The performance of the methods was analyzed through the comparison of the results considering the error index (ε). In this work, an IEEE 14 and 30 buses test cases were utilized.

For this purpose, an experimental evaluation using international standards IEEE 112, IEC 60034-2-1 and IEC 60034-2-3 (draft version), was set up. These standards estimated the induction machine’s efficiency based on a loss segregation approach to consider the stator, core, friction, rotor, stray-load, and additional losses contribution. Additionally, the machine’s losses were studied using a time-stepping, 2D, Finite Element Method (FEM) analysis on the open-source software Gmsh–GetDP. This analysis used voltage waveforms suggested by IEC 60034-2-3 and a motor design with the same rated characteristics to those used in the experimental stage.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123892170","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}

The wind turbine model includes the relation between the power coefficient, the tip speed ratio, and the pitch angle, and a Maximum Power Point Tracking (MPPT) strategy to define the torque reference. The stability analysis evaluated the critical clearance time (CCT) of three-phase faults in the 9-bus IEEE power system considering different levels of wind power penetration. Additionally, a wind turbine with a squirrel cage induction generator (SQIG), and synchronous generator cases were simulated as comparison patterns. Furthermore, to evaluate the power system transient performance with high penetration of DFIG generation, the Transient Stability Index (TSI) and the Transient Rotor Angle Severity Index (TRASI) were calculated and compared.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116488134","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}

A hierarchical control structure was established which basic principle is to decompose and coordinate highly complex systems and work them as subsystems. This hierarchical system was shaped by two layers. The first was a supervisory layer, in which initially the variable with major weight was found within the process to establish a hierarchy of variables, this was calculated through the decomposition into singular values of the Hankel matrix, also, considering the behavior of the plant in face of reference changes, it was sought to retune in line the parameters of the controllers arranged in the regulatory layer, this using fuzzy logic. The regulatory layer is the one that receives the parameters, which worked with independent control loops based on the structure of PID controllers that regulated the behavior of the four-tank system.","PeriodicalId":334574,"journal":{"name":"2018 IEEE Third Ecuador Technical Chapters Meeting (ETCM)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127058914","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}
