Modeling Of Grid Connected PV With Variable Solar Intensity<br>
<br>

<strong>Abstract</strong><br>
Distributed grid connected photo voltaic (PV) is performing a significant role as an electric supply resource and
as an integral part of grid. In this paper, a grid tie Neutral Point Clamped inverter is modeled and simulated as it can reduce
harmonics. Grid synchronization is another concern for grid interfaced system and need continuous monitoring of grid
variables. Hence, the reference frames for the injected current waveform is derived from grid variables such as frequency
and phase. This control algorithm of grid-tie inverter is simulated. A LCL filter is designed to improve the performance of
the solar PV system.
