Resumo: | This doctoral thesis proposes a method for regulating the secondary voltage of distribution systems based on the identification of ZIP models of the load (constant impedance, constant current and constant power) at the interface of medium and low voltage distribution networks. The proposed method considers the variation of the secondary voltage within the appropriate limits established in current regulations and the identification of the behavior of the load against this variation, which allows the equipment that regulates the secondary voltage to operate according to pre-established objectives, such as: reduction of losses, load shedding, control over the billing of utility companies and on the injection of distributed generation. For this, the geometric analysis of normalized ZIP load models is proposed in this paper, which in a generalized fashion, describes the behavior of the load power and/or current for voltage variations based on the coefficients that compose the model. It should be noticed that the proposed method is applicable to any equipment that allows variation of the magnitude of the grid voltage. In this work, the proposed method is employed considering as voltage regulating agents the transformers which employ electronic on-load tap changers, which are equipped with a bidirectional communication system, allowing: the regulation of the secondary voltage, the grid monitoring, it also allows obtaining the load model at the point of installation of the equipment and the definition of the optimization goal of the grid that the equipment must prioritize. Throughout the work are presented analyzes regarding the geometric interpretation of standardized ZIP models, as well as the proposed method for regulation of secondary voltage, experimental results regarding the obtaining of load models from electronic tap changers and simulation results employing the voltage regulation method proposed in a standard 13-bus IEEE distribution network. |

O método proposto considera a variação da tensão secundária dentro dos limites adequados previstos em normativa vigente e a identificação do comportamento da carga frente a essa variação, o que possibilita ao equipamento que regula a tensão secundária a operação de acordo com objetivos preestabelecidos, tais como: redução de perdas, contingenciamento de carga, controle sobre o faturamento das companhias concessionárias e sobre a injeção de geração distribuída. Para isso, é proposta neste trabalho a análise geométrica dos modelos de carga do tipo ZIP normalizados, que possibilita, de maneira generalizada, descrever o comportamento da potência e/ou corrente da carga para variações de tensão a partir dos coeficientes que compõem o modelo. Cabe destacar que o método proposto é aplicável a qualquer equipamento que possibilite a variação da magnitude da tensão da rede. Neste trabalho, o método proposto é empregado considerando como agentes de regulação da tensão secundária os transformadores com comutação eletrônica de taps, os quais são equipados com sistema de comunicação bidirecional, que possibilitam além da regulação da tensão secundária o monitoramento da rede e obtenção do modelo de carga no ponto de instalação do equipamento e a definição do objetivo de otimização da rede que o equipamento deve priorizar. Ao longo do trabalho são apresentadas análises referentes à interpretação geométrica dos modelos ZIP normalizados, bem como o método proposto para regulação da tensão secundária, além de resultados experimentais relativos à obtenção de modelos de carga a partir de comutadores eletrônicos de taps e resultados de simulação empregando o método de regulação de tensão proposto em uma rede de distribuição padrão de 13 barras da IEEE.Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPqporUniversidade Federal de Santa MariaCentro de TecnologiaPrograma de Pós-Graduação em Engenharia ElétricaUFSMBrasilEngenharia ElétricaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessEletrônica de potênciaModelo ZIPRegulação de tensãoPower electronicsZIP modelVoltage regulationCNPQ::ENGENHARIAS::ENGENHARIA ELETRICAEmprego de um comutador eletrônico de taps para regulação de tensão em redes elétricas a partir do modelo de cargaEmployment of an electronic on-load tap changer for voltage regulation in electrical grids based on the load modelinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisSchuch, Lucianohttp://lattes.cnpq.br/6395346342569490Beltrame, Rafael Concattohttp://lattes.cnpq.br/0818364721574204Heldwein, Marcelo Lobohttp://lattes.cnpq.br/4381538017805856Sperandio, Mauriciohttp://lattes.cnpq.br/8051956713222836Haffner, Sérgio Luíshttp://lattes.cnpq.br/4153337608992291Marchesan, Tiago Bandeirahttp://lattes.cnpq.br/2318413245910780http://lattes.cnpq.br/8817402421677386Quevedo, Josemar de Oliveira300400000007600c67316ac-85b7-465b-9a17-c8aee3a1c9eea9184165-1e05-4c35-8e9a-5387e154ade0850bdee4-096a-4a72-8016-3c5d3c9f1b479f4e9fea-4414-4b68-abe9-d9aeb147ce396e3a04c6-f7b7-4168-a2a1-8d015314dd3f60f7a862-50b0-4eaf-820b-17859c1b6af411dd6331-2eb5-4d46-a5ae-9eda760ef1f3reponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMCC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
