Description: This paper
presents a PSCAD/EMTDC model of PV solar panels, the grid
connected three phase voltage sourced inverter (VSI) and its
controller system. The VSI control is implemented with current
control loops. A maximum power point tracking (MPPT)
algorithm is implemented to get the maximum output power for
any given solar irradiation and temperature. This is integrated
with the inverter control in such a way that the requirement of
DC-DC converter is eliminated to harvest the maximum power.
The inverter model also maintains near unity power factor
regardless of the level of power output and maintains an
acceptable level of current harmonics. Finally, the developed
model is validated with the output of a commercially used PV
module.
