Lastprognoser
Lastprognoser, or load forecasts, are projections of future electricity demand used by power system operators, utilities, and energy markets to schedule generation, maintain reliability, and price electricity. Forecast horizons range from minutes to months, with short-term forecasts (hour-ahead to day-ahead) guiding balancing and unit commitment, and longer horizons informing capacity planning and investment decisions.
Inputs include historical load, weather variables (temperature, wind, solar radiation), calendar effects (weekday patterns, holidays), and
The forecasting process typically involves data collection and cleaning, feature engineering, model training and validation, forecast
Applications span grid operation and planning, including unit commitment, economic dispatch, balancing services, demand response, transmission
Challenges include data quality and resolution, model drift from changing usage patterns, integration of distributed resources,
