Battery Storage System Optimal Exploitation Through Physics-Based Model Predictive Control

Mario Paolone, Fabrizio Sossan, Sidi-Rachid Cherkaoui, Emil Namor, Dimitri Torregrossa

Traditionally, the safe operation of a battery energy storage system (BESS) is achieved by imposing conservative constraints on its DC bus current and voltage. By using a computationally efficient single particle model (SPM), we propose to replace these co ...

Model-free computation of ultra-short-term prediction intervals of solar irradiance

Jean-Yves Le Boudec, Mario Paolone, Dimitri Torregrossa

We propose an ultra-short-term dynamic interval predictor (DIP) of solar irradiance. Our DIP relies on experimentally observed correlations between the derivative of the solar irradiance and the forecast error in the next time-step. The main originalities ...
