Definition
Kraftprognoser (power forecasting) is the calculation of future electricity production (wind, solar, hydro) and consumption based on historical data, weather forecasts, temperature and market conditions. Forecasts are fundamental to balancing the power systemThe totality of facilities, lines and systems for producing, transmitting and distributing electrical energy.: production plans for hydropowerElectricity produced from the potential energy of falling water - Norway's dominant energy source (~90% of production) with a unique ability to ramp up and down quickly. are submitted the day before, and continuous adjustments take place in the regulating power market. Accuracy increases with shorter time horizons. Machine learning and AIArtificial Intelligence - technology that enables machines to perform tasks that normally require human intelligence, such as language understanding, pattern recognition, and decision-making. are significantly improving power forecasts, particularly for variable renewable sources such as wind and solar.
