Neste trabalho, apresenta-se uma estratégia de controle aplicada a um sistema para inserção de energia fotovoltaica na rede e compensação de tensão na carga. Como parte da estratégia de controle, faz-se uso de uma técnica que utiliza separadamente as componentes de sequência positiva, negativa e zero da tensão no Ponto de Acoplamento Comum (PAC), aqui denominada Decomposição Instantânea em Componentes de Sequência (DICSE). A metodologia proposta provê ao sistema a capacidade de operar adequadamente mesmo durante a ocorrência de faltas assimétricas no PAC. Para validar esta contribuição foram realizadas simulações em tempo real, onde o sistema foi submetido a dois diferentes tipos de faltas assimétricas. As faltas consideradas são do tipo curto-circuito. A partir dos resultados obtidos conclui-se que o método proposto é promissor, pois agrega mais robustez ao sistema, tendo em vista que a maioria das faltas ocorridas nos sistemas de distribuição são do tipo assimétricas.
