[en] 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.
