If you call runmarket as ...
define_constants;
[QUANTITY, PRICE, FCOST, VCOST, SCOST, PENALTY] = idx_disp;
[r, co, cb, f, dispatch, success, et] = runmarket(mpc, offers, bids, mkt,
mpopt);
There are two equivalent ways to get the cost ...
cost = totcost(r.gencost, r.gen(:, PG));
cost = dispatch(:, FCOST) + dispatch(:, VCOST);
And the profit (for generators) or benefit (for loads) is simply the revenue
minus the cost ...
profit = dispatch(:, QUANTITY) .* dispatch(:, PRICE) - cost;
Regarding the transformer, I had in mind something like ...
voltage_not_ok = 1;
while voltage_not_ok
r = runpf(mpc, mpopt); % or runmarket or whatever
if <voltage in r.bus(k, VM) too low>
<increase tap in mpc.branch(i, TAP)>
elseif <voltage in r.bus(k, VM) too high>
<decrease tap in mpc.branch(i, TAP)>
else
voltage_not_ok = 0; % exit the loop
end
end
That's just the overall idea. Obviously, you would have to make sure that your
tap update scheme does not result in cycling, etc.
Hope this helps,
