Renewable Generation Forecasting
How weather and resource data help estimate wind and solar output.
Systems note: terminology, market structures, voltage classes and reliability rules vary by jurisdiction. Use current local standards and utility information for real projects.
Where this fits
How weather and resource data help estimate wind and solar output.
Core system ideas
Forecasts convert weather expectations and plant characteristics into expected power output.
Error changes with forecast horizon and weather conditions.
Operators use forecast uncertainty when scheduling reserves, storage and other flexible resources.
Interfaces and tradeoffs
Planning uses scenarios because demand, resource additions, retirements, weather, project timing and technology are uncertain. Models are decision aids rather than perfect predictions.
What organizations measure
MAE/RMSE or other forecast error, ramp forecast, curtailment and availability.
