See Section 6.4.2 in the User’s Manual
<http://www.pserc.cornell.edu/matpower/docs/MATPOWER-manual-6.0b1.pdf> and the
load2disp()
<http://www.pserc.cornell.edu/matpower/docs/ref/matpower6.0b1/load2disp.html>
function.
When using dispatchable loads, as defined here, the objective function being
minimized is the negative of the net benefits (benefits to dispatchable loads
minus generation costs). Defining a dispatchable load with a marginal benefit
of $1000/MW is equivalent to saying the load has a $1000/MW cost of
curtailment. That is the OPF’s maximum net benefits solution will minimize the
cost of generation + the cost of demand response (load curtailment).
If you want to explicitly compute the cost of curtailment from the solved OPF
case, however, you will need to do it manually by extracting the quantity of
curtailment (difference between PG and PMIN for the dispatchable load) and
multiplying it by the cost of curtailment.
