SteadyEye

Solar forecasts for the next minutes, intra-hour and nowcasting

ABOUT

Forecasts based on real time sky imagery for very short-term solar forecasting needs

SteadyEye provides an advanced solar power production forecasting technology. This unique application delivers the most accurate forecasting solutions available on the market, to anticipate short-term solar variability.

Power generation and irradiance are forecasted up to 30 minutes ahead thanks to fine modelling of the cloud cover motion and its interaction with solar radiation, all integrated into an on-site all-sky imager.

KEY BENEFITS

OPTIMIZE PV RAMP MANAGEMENT

Thanks to the 15-seconds image acquisition frequency.

REDUCE HYBRID PLANT OPERATION COSTS

By increasing the use of solar energy.

FACILITATE BALANCING OF POWER GRIDS

And manage spinning reserves.

IMPROVE OFF-GRID ENERGY SYSTEM OPERATION

By fostering balancing of the system.

CUSTOMERS NEEDS

Particularly suitable for insular networks and hybrid systems. It favors real time management and decision making in order to optimize the alternative energy production methods to implement

HYBRID WITH STORAGE SYSTEMS

 

Microgrid studies, solar and wind forecasts to optimize the sizing and the management of hybrids systems (PV/Wind/Storage/Genset).

INSULAR POWER SYSTEMS

 

Studies to anticipate the meteorological impact on the grid during transition to renewable energies, solar and wind forecasts to reduce spinning reserve, and avoid grid instability.

POWER GRID MANAGEMENT

 

Solar and wind forecasts to reduce spinning reserve, and avoid grid instability.

METHODOLOGY

Local cloud information is acquired by one or several ground-based sky imager at a high frequency (up to 15 seconds) (step 1). The combination of these images and local weather measurement information are processed to simulate cloud motion vectors and optical depth to obtain forecasts up to 30 minutes ahead (step 2).

Forecasts are then optimized (step 3), by using production/irradiance observations, to take into account local phenomena, and by leveraging artificial intelligence technologies.

Ready-to-use forecasts, in a customized format, are then disseminated (step 4) through our proprietary web interface, csv files delivered via (S)FTP platforms or API.
