Métodos de pontos interiores para problema de fluxo de potência ótimo DC

Abstract

Os métodos de pontos interiores primal-dual e preditor-corretor são desenvolvidos para um modelo de fluxo de potência ótimo DC onde as leis de Kirchhoff são representadas por um problema de fluxo em redes com restrições adicionais. A estrutura matricial resultante é explorada reduzindo o sistema linear a ser resolvido a um sistema da dimensão do número de barras ou, opcionalmente, do número de laços independentes, cuja matriz é invariante ao longo das iterações permitindo que o método tenha uma iteração bastante rápida. Como conseqüência, um sistema linear cuja matriz varia a cada iteração deve ser resolvido. A dimensão deste sistema se reduz ao número de geradores. Resultados numéricos com implementação em C são apresentados para sistemas testes do IEEE e sistemas brasileiros de grande porte. O método de pontos interiores se mostra bastante robusto convergindo rapidamente para todos os casos testados.
