How do I run a load flow analysis for a solar PV array?

I simulated a microgrid on matlab simulink. I want to run a load flow analysis of the system. However matlab does not recognize the solar PV array in the microgrid as a source. When I place a load flow bus after the inverter of the PV array, it produces an error message saying the model does not converge. Increasing the number of iterations does not help. Any advice would be greatly appreciated

you can find it in simscape electrical library. just install add ons simscape and simscape electrial then you can find pv array in the library.

Hello Rusith,
the inverter is not supported for load flow, here are the supported blocks:

no, you will have to switch away from specialized power systems (simpowersystems) to Simscape (the blue blocks)
