PSPI: A Physics-Based Smart Persistent Model for Intra-Hour Solar Forecasting

Dec 17, 2019, 17:00 PM
PSPI improves the accuracy of the smart persistent model. It uses a cloud retrieval technique to estimate cloudy fraction and cloud albedo using surface-based observations of solar radiation. The solar radiation in future time steps is accurately given by actively computing individual cloud albedo related to the future solar position. PSPI significantly increases the accuracy of short-term forecasts of solar radiation, especially in thin cloud conditions.
