I am a PhD student and I am trying to model a pv connected grid by modefying the existing one using matlab. this is the orientation of the model. I have 10 pv arrays, each pv arrays is connected to boost converter and each 10 boost converter is connected to individual inverters. The 10 inverters are connected in parallel to grid. The problem is the output of the model is very noisy and is very small compare to the suppose power rating of the system. The system is using voltage source control. Does anyone know how to correct the output of my model. Thank you so much
