Dear friends,
When I run PV analysis and I got the message "Messages for api PVENGINE6. No in-service buses in subsystem "WORLD" (004269)". Then the program PSSE stops. But I can run QV analysis normally.
Please help me.
Thank you so much.
Okay, your main problem is that you only have one subsystem defined ('A'). Now, PV analysis is inherently different to QV analysis. When performing PV analysis, you need to define a source and a sink. As the process is progressed, more power will be transferred through a cutset of lines by adjusting the load/generation in the source and sink subsystems.
Your subsystem (SUB) file should be something like this:
SUBSYSTEM 'SOURCE'
BUS 100
END
SUBSYSTEM 'SINK'
BUS 101
BUS 102
BUS 103
BUS 104
BUS 105
BUS 106
END
END
Your MON file can then reference the SINK subsystem (or SOURCE if you want to include that too):
MONITOR LINES IN SUBSYSTEM SINK
MONITOR VOLTAGE DEVIATION ALL BUSES 0.1
END
END
Finally, your contingency file might look like this:
SINGLE BRANCH IN SUBSYSTEM 'SINK'
SINGLE BRANCH IN SUBSYSTEM 'SOURCE'
END
The things to be careful about:
Check the post "How PV Analysis work?" as well as "Can anybody help me with PV analysis in PSSE please?" and download the python files to run a script-based PV study.
Dear friend, i run pvf analysis as explained by the most of expert in this platform, i got a good result but i face a big problem, all contingincies are ine the zone that i selected in the sink area but i dont understand why in the bus voltage column the excell file show only buses in 60kV
The monitor (*.mon) file identifies which 'variables' are available for output (typical command line follows), monitor voltage range areas 1 99 kvrange 130 400 0.92 1.04
this is my mon file MONITOR TIES FROM SUBSYSTEM 'ZONE_ETUDE' MONITOR VOLTAGE RANGE KV 400 0.937 1.087 MONITOR VOLTAGE RANGE KV 225 0.910 1.087 MONITOR VOLTAGE RANGE KV 150 0.90 1.10 MONITOR VOLTAGE RANGE KV 60 0.90 1.10
but he show me all the buses and not only the buses in 'ZONE_ETUDE'!! how i can solve that problem? and also in column generator dispatch i see generator different form the area that i selected in 'ZONE_ETUDE'
In the mon file, the first line only check flow of ties. The next 4 lines monitors bus voltages at those kv levels (all buses?!) . The gen table show gens at the selected kv levels. for buses only a subsystem, enter [psee manual POM 8.1.3]: MONITOR VOLTAGE RANGE SUBSYSTEM 'ZONE_ETUDE' 0.9 1.1
Hi, Im trying to run the PV analysis on the IEEE 14 bus system and it keeps giving me an error stating : No participating dispatch buses in study system 'SOURCE'. The following is my .sub file
SUBSYSTEM 'SOURCE'
BUS 1
END
SUBSYSTEM 'SINK'
BUS 2
BUS 3
BUS 4
BUS 5
BUS 6
BUS 7
BUS 8
BUS 9
BUS 10
BUS 11
BUS 12
BUS 13
BUS 14
END
END
Bus 1 is a type 3, the swing bus. Since PV is a steady state process, it requires a swing bus to adjust for power unbalance during a load flow solution. Being the only 'source' element, it cannot be adjusted by the PV process and then re-adjusted by its swing bus property, resulting in an error.
In summary, The IEEE14 case is not suitable for a PV run for your subsystem setup. You can set type 2 generators as the source and some (or all) loads as the sink.
Hey, thanks for your quick response. So, do i exclude the swing bus completely from the .sub file?
yeah, try that.
so, that doesnt work too. Does every subsystem need to have a type 2 generator for PV analysis to work?
Dear friend,
Thank you so much for your comment. However, I put all machines and loads in "Service", I still have the same problem. If you don't mind, please give me your email then I send my file ( sav, con, mon, sub). Please run PV analysis and help me to solve the error. Thank you so much.
Regards,
Dear friend, I sent the files to your email. Please check them. Thank you so much.
Dear Eli Pack, Thank you very much for your help. The problem is solved. Regards,
I'm running PV for IEEE 9bus and have an similar error. I can't solve it. Can you help me?

It sounds like it might relate to how your source and sink subsystems are defined. Can you show your subsystem definition, and confirm that they have in-service generators and loads? If you are running the PV via Python, please include that line of code too.
