Grid balancing using FFR, Fast Frequency Reserve

The rise of renewable energy production, decommissioning of nuclear and coal power plants with high inertia, and increasing electricity demand have put a strain on the electrical power grid in many countries. New demand flexibility is needed to tackle power grid balancing issues. FFR, Fast Frequency Reserve is a method to rapidly shut down consumers when the demand is greater than the supply and the grid frequency is falling below a treshold. Typically the UPS will shut down in 0.7 seconds and run on the internal battery for 30 seconds in order to help stabilize the power grid. After a 15 minute re-charge of batteries the cycle can be repeated

Input(s):

• FFR start/stop request from grid owner.

Main feature(s):

• New datacenters can be seen as a resource in the power grid balancing rather than just a burden with high energy consumption. Batteries can be put in active use for revenue, not only passive backup.

Output(s):

• UPS power control
