Hi, everyone!
I want to divide the 30 buses and 6 generators into 3 areas in case 30.m, in
earlier messages, I find 'areas' don't affect the runopf(), but how in
runopf_w_res? And what are differences between 'area' and 'zone'? After reading
messages, I think areas are about buses and zones are about generators. Is it
correct about my understand?
I have two questions:
First, I do some modify in in the t_case30_userfcns.m, gen1 and gen2 are in
zone 1, gen5 and gen6 are in zone3, and gen3 and gen4 are in zone2. And every
zone's reserve requirements are 30MW.

The prices for zones are different in the 30MW and 20MW, how do they change?
And I'm not clear about Rmin mu, Rmax mu and Pmax mu.
And the second question is I want to divide 30 buses into 3 areas or zones, in
corresponding with generators. I find scale_load(), and I don't know if it is
right, and if it is necessary to do this division. Also, if it is necessary,
how to connect them?
load_zone = zeros(30, 1);
load_zone(1:9,11,28) = 1;
load_zone(12:20,23) = 2;
load_zone(10,21,22,24:27,29,30) = 3;
opt = struct('pq', 'P', 'scale', 'QUANTITY');
dmd = [30; 30; 30];
Thanks a lot!
Yang.
