This paper is a sequel to and builds upon the survey paper on optimal power flow (OPF)[4]. It
provides an up-to-date critical review of the recent major advancements in the OPF state-of …

We survey two aspects of mixed-integer nonlinear programming which have attracted less
attention (so far) than solution methods, solvers and applications: namely, whether the class …

This paper presents a computational platform for dynamic security assessment (DSA) of
large electricity grids, developed as part of the iTesla project. It leverages high performance …

This paper studies an extended formulation of the security constrained optimal power flow
(SCOPF) problem, which explicitly takes into account the probabilities of contingency events …

Significant growth in gas-fired generator use has strengthened the interdependence
between the electrical power systems and the natural gas systems. It is therefore imperative …

Power system planning and operation offers multitudinous opportunities for optimization
methods. In practice, these problems are generally large-scale, non-linear, subject to …

Power flow refers to the injection of power on the lines of an electrical grid, so that all the
injections at the nodes form a consistent flow within the network. Optimality, in this setting, is …

The secure integration of renewable generation into modern power systems requires an
appropriate assessment of the security of the system in real-time. The uncertainty associated …

Power flow refers to the injection of power on the lines of an electrical grid, so that all the
injections at the nodes form a consistent flow within the network. Optimality, in this setting, is …

We investigate a mixed-integer variant of the alternating current optimal flow problem. The
binary variables activate and deactivate power generators installed at a subset of nodes of …
