Forecasting of PV power application to PV power penetration in a microgrid

This paper treats the subject of Photovoltaic (PV) power forecasting. The power generated by a PV system is always nonlinear because of the variability of weather parameters such as solar irradiance and temperature. This variability present a major challenge in term of penetration of power into a microgrid plus the difficulty in control and management of grid. Moreover, to respond to all these equivocal, we use the forecasting applied to PV power which will injected into a grid. Many Approaches and strategies are found in the literature review, but the difficulty is how to find the convenient forecasting method to predict the power output of any PV plant. In this study we present the NARX model destined to predict the PV power.
