No participating dispatch buses in study system !?

unfortunately,i've checked all the related posts. Have you any ideas about the difference between dispatch methods !

In order to avoid complicate cas ,my subsystem source contain one generator bus and sink one non generator bus ,for mon file i don't think if there is a problem, on .mon file we chose juste voltage range and deviation

But the PV analysis is a transfer of generation between the source area and the sink area, so if there is no generation in the sink one, how he will dispatch the generation in this area? the is no plant to reduce

By reducing or increasing loads in the sink subsystem! Any way, I'm going to add generators into sink subsystem if that could resolve this issue

Dear friend @yaya , i've added generator in my sink subsystem ,but A new error replaces the old one it says : unable to increment transfer in the base case

if you want to reduce or increase loads, you can choose in transfer dispatch methods DFAX loads instead of DFAX generation
