Abstract:
This report focuses on best modelling of a photovoltaic cell by making it closed
loop. This model is based on mathematical equations and is described through an
equivalent circuit including a photocurrent source, a diode, a series resistor and a
shunt resistor. The developed model allows the prediction of PV cell behaviour under
different physical and environmental parameters. The model can also be used to
extract the physical parameters for a given solar PV cell as a function of temperature
and solar radiation. In addition, this study outlines the working principle of PV
module as well as PV array. In order to validate the developed model. The PV model
is connected into different grid systems and analysed the performance of different
systems. The comparative study also made in accordance with ripple output voltage
by using the result analysis dc grid connection and two stage ac grid connection is
made closed loop for the best performance.
