How does a DNO anticipate a blackout?

The European energy market context and the development of intermittent power generation on a massive scale may give rise to an increased risk of black-out phenomena. Although the probability of such an incident is fortunately very low, it would have a major impact on a distribution network operator in both economic and image terms. From the perspective of the network operator, if there is no action that can be taken to prevent the phenomenon occurring, a number of anticipatory measures can still be taken to minimise its operational impact by carrying out a robust analysis of vital infrastructure components and setting up an appropriate organisation that is able to deal effectively with such a situation.
