PV analyze in PSSE

The transmission network is basically a "transfer system" between two systems: the source (generators/plants) and the sink (load centers). PV analysis aims to statically determine the behavior of voltage while transmitting power from the source to load. Most of the time, bus voltage at the vicinity of the sink is depressed whenever power transfer takes place.

You need a subsystem because you want to study a particular system affected by the transfer of power, in this case, you need to check the relationship of power transfer against the bus voltage, hence P-V analysis.

It mean we have to creat 2 subsysem in whole large system, a source & a sink ?

Not necessarily limited to only 2 systems. You can actually create several subsystems in case you want to test inter-area transfers considering the behaviour of voltage.

OK..thank you so much

Can you tell me why I run PV analyze appear error " message for api PV_ENGIN_6. No participating dispatch buses in opposting system ' WEST' (000200)

Can you post your .sub file here?

I took file sanw in example to analysis PV. Maybe, I realized the wrong steps. I used this document. I don't know if it correct https://drive.google.com/file/d/0B4rCeFur8Pd6cmVZZ2VjSWNHRjg/view?usp=sharing

Use these settings: Source: STUDY Sink: EAST Max. Incremental MW: 500 Min. Incremental MW: 50 Tolerance: 10 MW Base case solution to allow adjustments. For Contingency solution, lock all control options. It should perform well.

I done it but it is still error

please copy and paste the contents of .sub file here.

SUBSYSTEM STUDY AREA 1 END SUBSYSTEM EAST AREA 2 END SUBSYSTEM WEST AREA 5 END END

Dear ffl, Thank you very much for your help. The problem is solved. Regards,

can you check if there is generation in your sub file? because it seems that there is no plant which participate in the dispatshing
