bus(es) manually, or you could use the extended OPF formulation (see Sections
6.3 and 7 in the MATPOWER User’s Manual) to apply constraints or costs to
voltage angles.

Dear Dr. Ray,
I want to develop algorithm for multi area coordination using voltage
angles as sharing variables in matpower pf. Kindly guide me how can i set
voltage angles in matpower so opf/pf start from that point and increase or
decrease angle further while following power flow constraints. I
The values in area and zone are not used at all by the power flow, CPF and OPF
routines. The area can be used by scale_load() to modify all loads in a given
area and there are options for viewing output summaries by area.

I think the case30 is sectioned into areas for the purpose of identifying
buses that belongs to the same power export/import area/zone.

Hello everyone,
I am working on congestion management for 30 bus system as given in
MATPOWER case.
I would like to know the role of AREA in the 30 bus system?
At some buses, it is 1, at other busses, it is 2 and 3 also.
What is the role of AREA and what is 1, 2 and 3?

I suppose it depends … do you want to minimize costs in the other areas as
well, subject to fixed exchange schedules? If so, yes, I think working with
toggle_iflims.m is best. If, on the other hand, you are only interested in
minimizing cost in one area, with the dispatches fixed in other areas
Dear Dr. Zimmerman,
Thanks a lot for your help.
I want to minimize the cost of generation of one area subject to a fixed
value for the exchange between all the other areas. Shall I still work with
toggle_iflims.m as you suggested or you have some other suggestions?
Thanks a lot.
Best,
Henry
Thanks a lot

Hi Matpower users,
Anybody have any ideas about how to calculate opf with the total import power
and export power specified?
Thanks a lot

Dear all,
I am trying to use OPF with area interchange being specified. I know how
much power is going to be import and export.
How can I do it using Matpower?
Thanks,
Henry
