The robust supply with electric power is fundamental for economy, industry
and our daily life. In periods of high loads the breakdown of a single
transmission line can cause a global cascade of failures implying
large-scale outages with potentially catastrophic consequences. Such periods
of high loads are expected to become more likely in the future, as electric
power from renewable sources is often generated far away from the consumers.
In this talk I will discuss the stability of power grids to transmission
line failures from a network science perspective, addressing the following
questions: Which links are indispensable for network operation? How does a
failure spread, i.e. which parts of a network are affected by the initial
failure? How can we efficiently detect those failures with few measurements?
