Dear Ray,
Thanks for your reply! Flexible, I mean, you see in run_w_res(), there is a
fixed value requirement for each reserve, and I don't want this fixed value,
can it just be a limit, so the reserve result will change when the load change.
For example, we give the 10MW for zone 1 with gen1 and gen2, so the sum reserve
of gen1 and gen2 is 10MW. But I want this 10MW to be a limit, and maybe the sum
reserve of gen1 and gen2 less than 10MW, it is not necessary for their sum to
be 10MW.
May I have ways to implement it?
Thanks a lot.
Yang.

I’m not sure what you mean by flexible. Do you mean price-dependent? The
current implementation does not include that.

Dear Ray,
In runopf_w_res() , the zonal requirement is fixed, but I want it to be
flexible, how can I do this ?
Thanks.

Hi Yang,
It’s not clear whether you simply want to use the fixed reserves extension (see
Section 7.6.1 in the MATPOWER User’s Manual) or you want to implement your own
OPF extension. In the first case you can simply use runopf_w_res(). In the
second, please see Chapter 7 and the code for the various extensions described
in Section 7.6.

Dear sir,
I want to do the extensible OPF, and I read paper MATPOWER’s Extensible Optimal
Power Flow Architecture.
The objective function is min f(x)+fu(x,z),and fu=sum(ci*ri), following the
code:
Ar = [I I];
om = add_vars(om, 'R', ng, [], Rmin, Rmax);
om = add_constraints(om, 'Pg_plus_R', Ar, [], Pmax, {'Pg', 'R'});
om = add_constraints(om, 'Rreq', Az, Rreq, [], {'R'});
om = add_costs(om, 'Rcost', struct('N',I,'Cw',Rcost), {'R'});
I add these into .m file, as for add_vars if I should change [], Rmin, Rmax
into data I need, and do the same with other codes.
I don't know if it's right.
Best regards.
Yang.
