A Microgrid is implemented with PSCAD/EMTDC software and three study cases, or operational modes of the Microgrid, are simulated. Initially a characterization of the power flows through the Microgrid is done, using the P-Q Theory, which facilitates the recognition of the main power issues that have to be compensated in the Microgrid. Then an SVC is implemented, using a control strategy based on fuzzy logic and genetic algorithms, in order to mitigate those power issues identified in the power flow characterization. It is important to take into account that all the simulations (the characterization and the compensation) are made for the three study cases running PSCAD and Matlab simultaneously.","PeriodicalId":330140,"journal":{"name":"2012 IEEE International Symposium on Alternative Energies and Energy Quality (SIFAE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117053401","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 implement the proposed methodology the data of two power transformers, located in different places and with different operational conditions, were considered. Real data from a data base was provided by utility Interconexión Eléctrica S.A. (ISA). To forecast the load curves a neural network was trained using MATLAB, being able to fit a load curve with daily and weekly prediction times. The proposed method allows the estimation of load curve values in power transformers with an average percentage of relative error around 10%. The method described in this paper can be applied to other equipment with similar operating characteristics.","PeriodicalId":330140,"journal":{"name":"2012 IEEE International Symposium on Alternative Energies and Energy Quality (SIFAE)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122620575","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}

This initiative of the government has strengthened very significantly the decision of higher education institutions and even secondary schools to advance the training of their students on the topic of renewable energy sources. ITSA has been carrying out projects, developing prototypes, scale models and simulations related to the subject, since its inception as an institution of higher education, mainly solar energy photovoltaic and solar thermal, wave energy systems and innovative initiatives such as utilization system for vehicle flow to generate electricity, or water reuse systems in shopping centers to save energy and water. Taking into account the importance of this research, teachers and students have participated in internal project samples, departmental events and national events, achieving important recognitions.

Such a methodology, developed by the authors, is the possibilistic harmonic load-flow.
