The increased share of distributed generation led to a higher loading of the transmission grid. TSOs have addressed the lack of investments in the grid due to the limited social acceptance of new transmission lines, through the installation of flow controllable devices. These devices allow to operate the power system closer to its limits. These devices can also be used to limit the impact of severe contingencies in the system. This paper addresses the effect of coordinated control of these devices on a small example case. By determining the HVDC set-points in a coordinated way, it is possible to extend the grid capabilities. The coordination of the power flow controlling devices can be done as a first measure in the security management procedures.
