1.4. Narrative of Use Case
Short description
RES generation is required for different purposes. This UC calculates the RES generarion forecast
Complete description
RES generation forecasts are needed by different actors and for different purposes, among others:
• For bidding in the different energy markets
• For assessing the security of the transmission grid
Each type of RES has its own forecasting algorithm and required inputs. For wind and solar generation, an accurate weather forecast is required. For hydro generation, besides weather forecast, it is also needed a forecasting of the water level in the reservoir, which may involve a modelling of the plant and historical data.
Additionally, any RES production forecast should take into account the following:
• Operational rules
• Scheduled maintenance periods
The operational rules for the RES do not change very often and can be modelled in the forecasting algorithm (e.g. maximum wind speed that the windmill supports or scheduled stops to avoid shadow flickering)
Scheduled maintenance periods cannot be predicted and thus there should be a procedure to agree and distribute information on these periods, in a request/approval scheme. The objective is that all the relevant actors are aware of the maintenance periods and these periods are taken into account in the calculation of the forecast. The role of the actor generating the forecast is the FORECASTING GENERATION CALCULATOR.
