Because the energy flow is not just non-constant but also erratic, the back-up systems also need to be extremely sensitive and capable of ramping up from shut-down to fully-on within a very short period of time to prevent grid instability and even collapse.

The minister said the exact reason for the collapse had not yet been pinpointed but, in the summer, "states try to take more power from the grid" and at the time of the collapse, the grid frequency was "above normal".
At the same time, an electric grid runs smoothly only when there is a balance of supply and demand.

World champion Hamilton, 24, struggled with understeer on a crucial sector of a flying lap in the first session of qualifying, from which five drivers are knocked out, and ended up among the last five drivers on the grid for only the second time in his career.
Using advanced computational techniques capable of analyzing streaming data from sensors across the grid in near real-time enable more dynamic monitoring of the entire power system across large geographic areas, and offers the potential to reach even higher levels of performance and cost-effectiveness through improved situational awareness.
