What is frequency control in the Nordic power system?
To securely operate a power system several attributes need to be controlled, one of these is the frequency. The purpose of this report is to give an overview to the frequency control in the Nordic power system. The report is mainly focused on the technical aspects related to frequency stability.
What is a Nordic power system?
The Nordic power system is designed for a nominal frequency of 50 Hz, however, the actual frequency always fluctuates around the nominal value depending on the imbalance between production and consumption. When there is more electricity production than consumption the frequency will start to increase and vice versa.
What is the normal frequency range in the Nordic power system?
Normal state is shown in green, Alert state in yellow and Emergency state in red. In the Nordic power system the standard frequency range is 50 Hz ±100 mHz. During large imbalance events the frequency is allowed to transiently deviate ±1000 mHz for up to 60 seconds, after which the frequency has to settle within ±500 mHz.
Do energy storage stations improve frequency stability?
With the rapid expansion of new energy, there is an urgent need to enhance the frequency stability of the power system. The energy storage (ES) stations make it possible effectively. However, the frequency regulation (FR) demand distribution ignores the influence caused by various resources with different characteristics in traditional strategies.
