PV analysis .sub file

I am trying to perform PV analysis but I am getting error: Messages for api PVENGINE1A No participating dispatch busses in opposing system "SINK" {000189}. I already defined a source and a sink in my .sub file but still I have the same problem. I tried to use in sink an existing area and it works, but I don't want to increase the load of this area, instead I want to increase the load of specific Zone, but I am facing this issue. Please help

Yes I used the same zone number as the load, but still facing same problem. Please find below .sub file:

Subsystem SOURCE
Zone 911
end
Subsystem SINK
Zone 221
end
Subsystem 132_Network
JOIN Group1
Area 8
Owner 433
end
end
Subsystem my_network
JOIN Group2
Area 9
Owner 443
end
end
Subsystem Yoga_plant
BUS 772
BUS 777
BUS 782
end
Subsystem Moka_plant
BUS 622
BUS 627
BUS 632
end
end

Hi, please check if the sink you specified has in-service generators.

No my sink does not have any generators, I think sink represents the load bus, which I want to increase its power. While source should contain the generators? Is my understanding correct?

There should be generators in both subsystems. For Source Subsystem, the generators you specify there will increase their dispatch while recognizing its limits. For the Sink Subsystem, the generators will decrease their output.

Maybe my understanding is wrong, but why would we need to reduce generation from sink side? We just want to examine how much power can be delivered to specific substation, wh ْ.ْ ile increasing its power until we face voltage collapse, this is the definition of PV analysis right?

The reduction of generation in the Sink subsystem is for the purpose of balancing the generation-demand of the power system.

Can you post the SUB file?

Source and Sink regions (areas, zones, or any grouping combination allowed) have unique elements. Also check that the zone number exists in the case and it contains loads. Remember that load's zones numbers may be different than its bus zone numbers.

Make sure on main PV menu, in section "Transfer dispatch methods" -> "For opposing sink system", select DFAX load.

Yes thats what I selected, PV worked for me after inserting some generation at sink zone, but I got another issue, where the PV analysis is not really reflecting how much power can certain zone handle before it collapses. Where, the PV stopped increasing at 250MW.. continue next comment.

but later I increased the load manually and I was able to increase even up to 600 MW without problem
