Comparison of solar panel models for grid integrations studies: Harmonics and voltage disturbances

The photovoltaic systems are extremely dependents on the climatic conditions in which they are submitted. For to represent this influence, there are in the literature three models of the solar photovoltaic panel: the equivalent circuit, the mathematical model and the multi-physical model. This paper compares these models using a grid connected photovoltaic system. Simulations of grid disturbances, like harmonics and voltage sags are made for observed the behavior of each model.
