SteadySat offerta

 

Associata alle previsioni meteorologiche, l’elaborazione di immagini satellitari consente di affinare l’evoluzione della copertura nuvolosa e il profilo di produzione per le ore successive. Questo modulo utilizza immagini satellitari raccolte da 1 a 4 volte all’ora. Grazie a una modellazione dettagliata e ad algoritmi matematici evoluti, la produzione energetica delle ore successive viene predetta con una maggior capacità di valutare le fluttuazioni e i rischi di intermittenza.

A titolo esemplificativo, in un mix energetico che comporta una parte significativa di energia solare, quest’offerta consentirà di modulare le necessità in termini di energia termica complementare. Risultato: riduzione dei costi di esercizio e miglior bilancio a livello di CO2.

Schema SteadySat (it)

The solar forecast service SteadySat was developed in response to intra-day forecasting needs (up to 6 hours in advance) and is intended primarily for network operators (TSOs and DSOs), but also for electricity producers, traders or suppliers. This production forecast service allows in particular to:

> Manage the injection gap recorded during the day compared to the previous day’s announcement, and reduce associated costs (penalties, risks);

> Set up and operate a storage system associated with a solar power plant;

> Efficiently exploit solar resources in an island environment or in non-interconnected areas, while reducing the use of fossil fuel energy;

> Manage the hybridization of a fossil fuel off-grid power plant using solar power to reduce the average cost per MWh locally produced;

> Manage a micro-grid network operating multiple power assets to maximize the use of the solar resource.

Coupled to weather forecast (SteadyMet), satellite imagery allows more accurate evaluation of cloud cover evolution and production profile over the coming hours. This module uses satellite images collected 1-4 times per hour. Through detailed modelling and advanced mathematical algorithms, energy production is predicted over the following hours with increased capability for assessing fluctuation risks and intermittency.
