Experiments with the interior-point method for solving large scale Optimal Power Flow problems

This paper reports extensive results obtained with the interior-point method (IPM) for nonlinear programmes (NLPs) stemming from large-scale and severely constrained classical Optimal Power Flow (OPF) and Security-Constrained Optimal Power Flow (SCOPF) problems. The paper discusses transparently the problems encountered such as convergence reliability and speed issues of the method.

► We report extensive results obtained with the interior-point method on large scale Optimal Power Flow problems.
► We discuss transparently the convergence reliability and speed issues of the method.
► The computational effort of the OPF application is acceptable while the SCOPF requires simplified post-contingency models.
