Abstract
In this work, a PV-based Distribution Static Compensator (DSTATCOM) system has been integrated into the three-phase grid having linear/non-linear loading conditions. The complete DSTATCOM system has two stage converters i.e., DC-DC converter and voltage source converter (VSC). DC-DC converter has been controlled by the Incremental Conductance based MPPT algorithm while the voltage source converter has been controlled by the power balance theory (PBT)/ unit vector template (UVT) technique. These two converters are coupled with a DC link and connected at the common intersection point of the grid. The complete PV-based DSTATCOM system along with the grid has been developed and executed in the MATLAB/Simulink platform. The power quality performances have been observed in terms of DC voltage regulation and grid current harmonics mitigation for linear/non-linear loading conditions. Moreover, the THD regulation for the grid current has been verified by the IEEE 519–2014 and IEC 6100–3–2 standard.
