The aim of the present work is to propose and describe a complete photovoltaic DC source model that can supply grid connected inverters, which are usually employed in distributed generation plants as interconnection to the power system. The main advantage of this model is that all non ideal characteristics of the photovoltaic (PV) source are taking into account, and complex weather conditions patterns can be included in the model to simulate, study and predict the effects of increasing penetration of PV generators in the grid. The model includes: A photovoltaic array consisting of 34 photovoltaic modules with total peak power of 7412 Wp and a boost-buck DC-DC converter that operates to assure maximum power extraction by using a maximum power point tracking (MPPT) algorithm based on the incremental conductance method.
