Abstract

In this paper, practical approaches dealing with some application issues in a direct nonlinear interior point algorithm (DNIPA) for optimal power flows (OPF) are presented. These issues include hot start, warm start, initialization and decoupling. These approaches effectively enhance the performance of DNIPA for OPF problems in terms of iteration counts and CPU times. Numerical results carried out on a 244-bus system are reported. These results show that the proposed approaches are promising in practice for the use of DNIPA in solving OPF problems.
