The solver has been built in order to solve transient problems of circuit theory that feature fractional and nonlinear circuit elements (i.e. fractional coils and fractional capacitors that can even be nonlinear elements). The problems lead to a general form of fractional differential-algebraic equations. The introduced numerical solver relies on the SubIval numerical method, which is briefly recalled. The options for the solver are given and a simple circuit example containing fractional and nonlinear elements is considered. The problem is solved and the results are presented and analyzed along with the error estimation results.","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131814887","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 suggests that it is necessary to implement modern technologies in the management of distribution systems capable of providing alternatives for decision making in a fast and economically viable manner supported by periodic studies with technical and economic bases. This work summarizes the first stage of the implementation of ETAP 18.1.0 Electrical Power System Analysis, software used for the study of the Villarrica distribution network carried out by the Compañía de Luz y Fuerza S.A. (CLYFSA), company in charge of the supply of electrical energy in the city of Villarrica since 1953 and currently has more than 14.000 users. The software is used for the modeling of the entire medium voltage electrical distribution system (including public and exclusive transformers, capacitor bank, pre-assembled and protected distribution lines, etc.) and then perform simulations for different operating states of the system and loading conditions These simulations in turn are used to evaluate the decision making of alternatives that improve the reliability and robustness of the electrical system in such a way to improve the quality of service.","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","volume":"17 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131924223","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 motivation for the development of these techniques came from structure-preserving matrix approximation problems that appear in the fields of system identification and model predictive control, for data-driven systems and processes. The research reported in this document is focused on finite-state approximation of data-driven systems. Some numerical implementations of the aforementioned techniques in the simulation and model predictive control of some generic data-driven systems, that are related to electrical signal transmission models, are outlined.","PeriodicalId":272652,"journal":{"name":"2019 IEEE 39th Central America and Panama Convention (CONCAPAN XXXIX)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127518991","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}
