Definition
Kraftbalanse (power balance) is the physical state in which total power generation in the grid is at all times equal to total consumption plus transmission losses. If the balance is broken, the frequency changes (nominally 50 Hz) - excess generation drives the frequency up, insufficient generation drives it down. StatnettNorway's system operator for the transmission grid - owns and operates the high-voltage network and operates Elhub., as TSOTransmission System Operator - responsible for operation and balance of the transmission grid at national level. (Transmission System Operator), is responsible for maintaining the balance in the Norwegian grid, including through the regulating power market (the RK market) and primary/secondary reserves. Parties with balance responsibility (BRPs) are obliged to submit expected production and consumption profiles to Statnett, and deviations are settled financially. The Nordic power system (Norway, Sweden, Denmark, Finland) is closely coupled, and balance is managed at system level through cooperation within ENTSO-EEuropean Network of Transmission System Operators for Electricity - collaborative body for European TSOs coordinating joint grid operations and regulations..
