A Fractional-Order Dynamic Pv Model

A dynamic model of Photo-Voltaic (PV) solar module is important when it is utilized in conjunction with switching circuits and in grid connected applications. In this paper, a fractional-order dynamical model of a PV source is introduced. The model includes both a fractional series inductor and a parallel capacitor which are in general of two different orders allowing for extra degrees of modeling freedom. An expression for the load current is derived and the step response is investigated for different orders. It is found that the nature of the connections has a dominant effect on the response in comparison with the nature of the PV itself. The abstract goes here. The length of the abstract should not exceed 150 words.
