Title in Portuguese
Gerenciamento e controle de uma microrrede CC: uma proposta de compartilhamento de energia entre carregador de veículos elétricos e rede de distribuição
Keywords in Portuguese
compartilhamento de carga
conversores de potência
curvas sigmoides
Eletrônica de Potência
gerenciamento de microrredes CC
Abstract in Portuguese
Neste trabalho é proposta uma estratégia SoC-adaptativa para o gerenciamento e compartilhamento de potência para microrredes CC, capaz de integrar veículos elétricos (VEs), fontes de energia alternativa e a rede de distribuição de forma bidirecional, constituindo um hub para serviços de geração com energias renováveis, Grid-to-Vehicle (G2V) e Vehicle-to-Grid (V2G). A estratégia de gerenciamento proposta combina o uso de funções sigmóides e controladores PI, habilitando a inclusão de fatores importantes como o estado de carga (SoC), limites de corrente pertinentes e o compartilhamento de carga por parte dos conversores de potência utilizados. A análise de estabilidade da estrutura de controle é realizada através do software Simulink®. A estratégia é então simulada através do software PSIM® e finalmente experimentada usando a plataforma Typhoon® HIL602+ para demonstrar seu comportamento e validar sua efetividade através de simulação em tempo real.

Abstract in English
This thesis proposes a SoC-adaptive management and power sharing strategy between DC microgrids, electric vehicle chargers and distribution grid, providing bidirectional energy flow, functioning as a service hub of renewable energy generation, Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G). The proposed strategy merges sigmoidal functions and PI controllers allowing the inclusion of relevant factors as battery state of charge (SoC), current limits and load sharing between power converters. The stability analysis of the control structure is performed using Simulink® software package. The strategy is simulated through PSIM® software package and further tested using Typhoon® HIL602+ test-bench to demonstrate its behavior and to validate its effectiveness.
