Resumo: This dissertation presents the control system for a DC-Nanogrid based on the DCBus Signalling technique. Converter principle of operation is described and its control loops are designed. Modulation geometric approach is used in order to simplify the mathematical modelling and its inner current loop. In order to maximize the power extracted from the photovoltaic arrangement, a maximum power point tracking algorithm is implemented in a indirect way, regulating the input DC-bus voltage. NIBB converter operates in closed loop, using a faster inner inductor current, using the voltage across the inductor as control variable as well as two outer voltage slower loops, so it would be possible to regulate both input and output voltages (V1 and V2). Both simulation and experimental results corroborate the theoretical analysis about the efficiency improving on the BBNI converter as it can be modulated by modifying a auxiliar voltage, adding a degree of freedom in the PWM modulation.

O princípio de operação do Conversor Buck-Boost Não-Inversor (BBNI) é descrito e suas malhas de controle são projetadas. A abordagem geométrica para a modulação PWM é utilizada para simplificar a estrutura de controle e modelagem matemática para a malha interna de corrente, fazendo com que esta seja bidirecional e comum para os dois modos de operação do conversor. Para extrair a maxima potência do módulo fotovoltaico, o rastreamento do ponto de maxima potência (MPPT - Maximum Power Point Tracking) é realizado de maneira indireta, controlando o barramento de entrada do conversor. O Conversor BBNI opera em malha fechada utilizando uma malha rápida de corrente do indutor e usando a tensão sob o indutor como variável de controle e duas malhas externas mais lentas (droop e regulacão da tensão de entrada). Os resultados de simulação e experimentais corroboram as análises teóricas acerca da melhora na eficiência do conversor BBNI visto que este é modulado utilizando uma variável auxiliar, a qual adiciona um grau de liberdade adicional para a modulação PWM.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade 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/openAccessModulação geometricaSinalização pela tensão do barramento CCNanorrede CCControle droopConversor buck-boost não-inversorNon-inverting buck-boost converterGeometric modulationDC-bus signallingDroop controlCNPQ::ENGENHARIAS::ENGENHARIA ELETRICAModelagem geométrica do conversor buck-boost não-inversor usado na interface de nanorrede CC residencialGeometric modelling of the non-inverting buck-boost converter as interface for residential DC nanogridinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisMartins, Mário Lúcio da Silvahttp://lattes.cnpq.br/2730012969211616Lopes, Luiz Antonio CorreaLopes, Luiz Antonio CorreaFont, Carlos Henrique IllaGrigoletto, Felipe Bovolinihttp://lattes.cnpq.br/8659952713500017Ribeiro, Gustavo Colpes3004000000076006006006006004450a16e-aa18-4d50-a97e-49469130b8d60db6d845-819d-4fe5-adf5-3b6404e6f119b37c79c2-0776-4b27-86c1-7ea95cb046247e5c0b1a-1f3f-47c2-b3c1-edbac5a5a9465824c38f-3adc-4c06-ad2a-514e89595ac9ff495058-c72f-43d4-a408-8adeff1dc1a1reponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGEE_2021_RIBEIRO_GUSTAVO.pdfDIS_PPGEE_2021_RIBEIRO_GUSTAVO.pdfDissertação de Mestradoapplication/pdf4883996http://repositorio.ufsm.br/bitstream/1/22706/1/DIS_PPGEE_2021_RIBEIRO_GUSTAVO.pdf85f54d43b337e3629b27db5ab8f9a9bdMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

description This dissertation presents the control system for a DC-Nanogrid based on the DCBus Signalling technique. Converter principle of operation is described and its control loops are designed. Modulation geometric approach is used in order to simplify the mathematical modelling and its inner current loop. In order to maximize the power extracted from the photovoltaic arrangement, a maximum power point tracking algorithm is implemented in a indirect way, regulating the input DC-bus voltage. NIBB converter operates in closed loop, using a faster inner inductor current, using the voltage across the inductor as control variable as well as two outer voltage slower loops, so it would be possible to regulate both input and output voltages (V1 and V2). Both simulation and experimental results corroborate the theoretical analysis about the efficiency improving on the BBNI converter as it can be modulated by modifying a auxiliar voltage, adding a degree of freedom in the PWM modulation.
