Analytical model for PV — Distributed generators, suitable for power systems studies

As PV - distributed generation (DG-PV) penetration increases, its reaction with various system disturbances (i.e. voltage drop, short circuit, frequency deviation) has to be taken into account during relative system studies. Though for wind farm generation (WFG) a lot of effort has been made for the development of appropriate models, there is still a lot of progress to be done in the field of PV Generation modelling and especially for DG-PV. This paper presents an analytical model for the case of DG-PV containing a full bridge SPWM inverter, suitable for integration into power system studies. The model will be used to describe the DG-PV behavior under several typical system disturbances, both for the case of grid connection as for the case of an isolated microgrid. Finally, MATLAB/Simulink simulation environment will be used in order to integrate the proposed DG-PV model into a system model.
