PSCAD/EMTDC model for photovoltaic modules with MPPT based on manufacturer specifications

Commonly used simulation models for photovoltaic arrays often require the knowledge of unavailable parameters and the calculation of equivalent resistances to be used. Those resistances are not provided by manufacturers and their calculation makes the application of the designed models difficult. This paper proposes a photovoltaic panel or array model based on the specifications provided by manufacturers in datasheets. The model emulates the characteristic curves declared by the panel manufacturer and an integrated MPPT (Maximum Power Point Tracking) technique. The well-known PSCAD/EMTDC software has been selected to develop the proposed model and commercial panels have been used for validation.
