Grid-Tied PV design

Hi Guys,

Currently I’m doing research topic on this power quality PV module integrated grid. I need to pick any of the power quality issues e.g: harmonics,voltage fluctuation,voltage reg etc. I would like to ask for some guidance on what should I basically include in my design? Basically, my idea is to design the PV module attached to the grid(include transformers,buses etc..) then simulate and determinet the power quality issues then fix them by finding solutions to the power quality issues. But I don’t really know what should be included in my designs besides those I’ve mentioned.

Btw,I’m new to this forum.If I’ve posted in the wrong section or anything.Please do lemme know. Many thanks.
