RUNOPF_W_RES Runs an optimal power flow with fixed zonal reserves.
RESULTS = RUNOPF_W_RES(CASEDATA, MPOPT, FNAME, SOLVEDCASE)
[RESULTS, SUCCESS] = RUNOPF_W_RES(CASEDATA, MPOPT, FNAME, SOLVEDCASE)
Runs an optimal power flow with the addition of reserve requirements
specified as a set of fixed zonal reserves. See RUNOPF for a
description of the input and output arguments, which are the same,
with the exception that the case file or struct CASEDATA must define
a 'reserves' field, which is a struct with the following fields:
zones nrz x ng, zone(i, j) = 1, if gen j belongs to zone i
0, otherwise
req nrz x 1, zonal reserve requirement in MW
cost (ng or ngr) x 1, cost of reserves in $/MW
qty (ng or ngr) x 1, max quantity of reserves in MW (optional)
where nrz is the number of reserve zones and ngr is the number of
generators belonging to at least one reserve zone and ng is the total
number of generators.
In addition to the normal OPF output, the RESULTS struct contains a
new 'reserves' field with the following fields, in addition to those
provided in the input:
R - ng x 1, reserves provided by each gen in MW
Rmin - ng x 1, lower limit on reserves provided by each gen, (MW)
Rmax - ng x 1, upper limit on reserves provided by each gen, (MW)
mu.l - ng x 1, shadow price on reserve lower limit, ($/MW)
mu.u - ng x 1, shadow price on reserve upper limit, ($/MW)
mu.Pmax - ng x 1, shadow price on Pg + R <= Pmax constraint, ($/MW)
prc - ng x 1, reserve price for each gen equal to maximum of the
shadow prices on the zonal requirement constraint
for each zone the generator belongs to
See T_CASE30_USERFCNS for an example case file with fixed reserves,
and TOGGLE_RESERVES for the implementation.
Calling syntax options:
results = runopf_w_res(casedata);
results = runopf_w_res(casedata, mpopt);
results = runopf_w_res(casedata, mpopt, fname);
results = runopf_w_res(casedata, mpopt, fname, solvedcase);
[results, success] = runopf_w_res(...);
Example:
results = runopf_w_res('t_case30_userfcns');
