Hi Everyone,

Currently I'm working on the power quality issue on PV grid-tied. Basically, I've designed a solar panel, buck-boost converter, battery storage(optional) and three-phase grid model in Simulink. However, I've problems in connecting them on the grid model. Would anyone kind enough to help me on this? Many thanks.

 

How can we help if we don't know the nature of the problems you are having?

 

Hi Crutschow,

Sorry about the previous post. Actually, I'm supposed to measure the harmonics on this solar pv grid-tied. Since, I've already constructed the three-phase grid model in Simulink. Now, I'm trying to connect the pv array with buck-boost converter before connecting them to the three-phase inverter to connect it to the three-phase grid. The below attachment are my designs in Simulink. I hope you could guide me on where it went wrong so I could rectify my mistakes. Many thanks.
