Abstract
The paper presents an automatic active power modulation control that has been developed and implemented to handle the potential overload that can appear in case of loss of one or more of the export cables of the Modular Offshore Grid (MOG) installed in the Belgian Coastal Area. The automatic controller, implemented in the Energy Management System (EMS) of ELIA sends setpoints of active power to the different wind parks, that have a total installed power of 1 GW taking into account not only the current and potential future topology (i.e. potential additional incidents) and the forecast of ampacity calculated by a Real Time Thermal Rating system installed on the cables. The robustness and reliability of the system has been enhanced with the addition of dynamic alarms, automatic detection of non-compliant control actions from the parks and a local backup protection that disconnects automatically the cables in case of prolonged unacceptable overload.
