PVSCOPE™ combines and offsets meteorogical models, satellite images and real-time measurements to minimize prediction errors for each geographical scale and for each time horizon.
Our software merges multiple forecasts to generate the most accurate prediction :
1-Use of data from local observation : PV production measurement are collected by the information system installed on the production site (10 min timestep)
2- Use of satellite data : satellite images are provided by the Centre for Space Meteorology (10 to 30 min timestep).
3- Use of meteorological modelisation : day weather forecasts are recovered from agencies that perform the weather forecast and reactualize all 12h.
Then, this data are used to generate forecasts using several innovative algorithmic methods:
- Corrected persistence models from measured production data (Very short term, less than 1h)
- Forecast from geostationary satellite observations (Short term. Between 1h and 6h.)
- Climatology-based forecast (Between 6h and 24h)
- Forecast from meteorological numerical prediction (Between 6h and 24h)
- Merging multiple forecasts to minimize prediction error
PVSCOPE™ was developed in partnership with the Dynamical Meteorology Lab (Ecole Polytechnique, Paris), for generating day-ahead and intraday PV power production forecasts.
