Inertia’s new frontier

As the amount of traditional inertia on our grid systems decreases with the shift to inverter-based resources like wind and solar photovoltaics (PV), system operators are increasingly seeking carbon-free alternatives for stabilising frequency

New rapid response technologies mean less inertia is required

STABILISING FORCE Rotating masses in power plants provide grids with inertia to cushion sudden changes in frequency

ALL ABOUT SPEED The more quickly you are able to react to changes in frequency, the less inertia is needed

KEY QUOTE Today we can run smaller systems fully based on power electronics so they can simulate the behaviour of synchronous generators and respond just as quickly

The vital missing links of the energy transition in Europe

No matter how much wind and solar power is generated, the energy transition cannot be achieved without a built-for-purpose electricity infrastructure. Gaps in the interconnections of Europe’s grid network and lack of capacity on the wires where it is needed most will halt green electrification of energy.

The grid in search of a brain

Around 50% of the shift from fossil fuels to renewable forms of energy has been a digitised transition to 2020, says Energinet, Denmark's power system operator. As the world digitises further, the already vast volumes of data will only increase in mass. Advances in Artificial Intelligence technology and machine learning tools provide ways of processing this tsunami of data into a new world order
