摘要

The integration of intermittent renewable energy in the energy mix is currently limited to a threshold of 30% of the total power being produced. This restriction aims at ensuring the safety of the power input. The elimination of this technical obstacle will be possible with solutions to energy intermittence of wind and solar energy. The energy issues which islands are facing today prefigure global problems in a more or less long term. These territories constitute unique laboratories for testing new technologies of storage, management and forecasting of energy. The contribution of this thesis focuses on the forecasting of global horizontal irradiance at different time horizons. Indeed, the generated PV power stems directly from the intensity of the global horizontal irradiance. First, the review of solar irradiance forecasting methods allows to classify numerical weather models and statistical forecasting methods depending on spatial and temporal resolution. Moreover, it shows that best performance is obtained with hybrid models. Second, a short-term forecast model (day ahead forecast) is developed with the Weather Research and Forecasting model (WRF) and a Bayesian neural network. The hybridization of these methods improves the day ahead forecast performance. Third, a model for forecasting the very short term is developped with the Kalman hybrid model. This method offers on the one hand an energy forecasting and on the other hand a multi-horizon forecast. Comparing the performance of the aforesaid with the reference method, namely the persistence method, shows an improvement of the quality of the forecasts. Combining the Kalman filter with the WRF numerical model allows an operational implementation of the forecast.
