Fluctuating photovoltaic (PV) power creates a challenge for grid energy management as energy penetration increases rapidly. As a result, the forecasting of PV energy has become essential to ensure grid stability and promote optimal use of energy resources and more economical distribution. The objective of this work is to forecast PV power for a 10 min horizon, based on a set of data. This approach is used to ensure efficient operation of the fluctuating output of a PV station charging a station for electic vehicules. Simulation results show the reliability and efficiency of the technique.
