Zonal Grid Limitations

[Marija Ch.]

Hello,

I'm working on a PV project that is divided into 9 zones, each with its own grid export limit of 4.44 MW AC. Overpaneling is allowed, so the DC side can exceed this limit. In total, the full plant would have 40 MW AC and potentially more on the DC side.

I know PVsyst allows setting a Grid Power Injection Limit at the system level, but I haven't found a way to apply individual grid export limits per zone within a single simulation.

Is there a way to simulate per-zone injection limits in one project? Or is it necessary to simulate each zone separately and then aggregate the results?

Thanks in advance for your help!

Hello Marija,

Indeed, the only possibility is to apply a grid limit for the full system. As you suggest, a workaround would be to create a variant for each sub-system and aggregate the results. I will note your use-case for possible future development of for instance having the possibility to define the limitation per sub-array (as for the ohmic losses for instance). 

Thank you reaching out

Modifying the OND file is another way
