Abstract in Portuguese
Este projeto de pesquisa teve o objetivo de desenvolver uma nova abordagem para a resolução do Fluxo de Potência Ótimo. Para isso, foram obtidos dados teóricos, a partir de um levantamento bibliográfico, que explicitaram os conceitos de otimização aplicados ao sistema estático de energia elétrica. A pesquisa fundamentou-se metodologicamente nos métodos: Newton-Langragiano, Penalidade e Função Barreira Logarítmica de Newton Projetada. Os sistemas de equações resultantes das condições de estacionaridade da função Lagrangiana foram resolvidos pelo método de Newton. Na implementação computacional foram utilizadas técnicas de esparsidade. Foram realizadas estudos para validação e a verificação da abordagem proposta nos sistemas de 3, 14, 30 e 118 barras.

Abstract in English
This research project had the objective of developing a new approach for the resolution of the Optimum Power Flow. For this purpose, theoretical data were obtained through a bibliographical survey, which explained the optimization concepts applied to the electrical energy static system. The research was based on the methods: Newton-Lagrangian, Penalty and Projected Newton Barrier Function. The systems of equations resulting from the Lagrangian function stationarity conditions were resolved through the Newton's method. In the computational implementation, sparsity techniques had been used. Studies had been carried out for the proposed approach validation and verification in the systems of 3, 14, 30 and 118 buses.
