Efficient handling of power system balance in a future with close to 100% renewable power

Wind power has grown strongly in recent years and is expected to continue to increase significantly. Solar power is also expected to increase.

In a power system, a continuous balance is maintained between production and consumption. In the Nordic power system, this is currently handled mainly by hydropower. With large amounts of wind and solar power, it will be a challenge to maintain this balance. The system becomes more volatile with changing conditions between different states.

Even in this system, the continuous balance between production and consumption must be maintained. At present, in 2020, there are several different support services for balancing, which affect each other: FFR, FCR, aFRR, mFRR, time shift trading etc.

The aim of this project is to estimate future imbalances and the need for support services. These will vary from hour to hour in a future, entirely renewable, electricity generation system. The basic system has much higher consumption, and more flexibility.
