Keeping system security
Since the power lines are operating at their limits and congestion is on the rise, real-time coordination has become a key to ensure a safe supply at any time, especially with other European TSOs and with DSOs (distribution system operators).
Various measures are taken like re-dispatching, curtailing wind power, even controlled brownouts, etc. to secure the electricity system. These measures can be preventative or operative and can be employed nationally or internationally.
Measures: Activating reserves, re-dispatching, curtailing wind power and controlled load reductions
