Challenges for the grids of the future

Electricity markets

optimal utilization of regional advantages

(further) growth of interconnected systems

short-term changes in load flow

restricted access to informationfor system operators

Renewable energy generation far away from consumption

volatility of generation

The grids of the future must be more flexiblethan in the past from structural as well as

from operational point of view!
