Lightweight hybrid local PV short term forecasting using both physics and data
Résumé
There is an increase of PV generation on many distributed sites, especially rooftop PV on buildings. The emergence of aware end-users, that are doing their best to maximize their auto-consumption in an energy community using energy management systems, leads to a need for new adapted forecasting models. We ask the question in this article of the ability to produce with few data, a robust day ahead PV generation forecasting. To do that, we have applied a hybrid methodology taking advantage of both physical model and data-based model in order to reduce the amount and kind of data. We reach improvements from 5% to 12% depending on the model used, compared to pure data-based approaches.
