RUNMARKET Runs PowerWeb-style smart market.
[RESULTS, CO, CB, F, DISPATCH, SUCCESS, ET] = ...
RUNMARKET(MPC, OFFERS, BIDS, MKT, MPOPT, FNAME, SOLVEDCASE)
Computes the new generation and price schedules (cleared offers and bids)
based on the OFFERS and BIDS submitted. See OFF2CASE for a
description of the OFFERS and BIDS arguments. MKT is a struct with the
following fields:
auction_type - market used for dispatch and pricing
t - time duration of the dispatch period in hours
u0 - vector of gen commitment status from prev period
lim - offer/bid/price limits (see 'help pricelimits')
OPF - 'AC' or 'DC', default is 'AC'
MPOPT is an optional MATPOWER options struct (see MPOPTION for
details). The values for the auction_type field are defined as follows:
0 - discriminative pricing (price equal to offer or bid)
1 - last accepted offer auction
2 - first rejected offer auction
3 - last accepted bid auction
4 - first rejected bid auction
5 - first price auction (marginal unit, offer or bid, sets the price)
6 - second price auction (if offer is marginal, then price is set
by min(FRO,LAB), if bid, then max(FRB,LAO)
7 - split the difference pricing (price set by last accepted offer & bid)
8 - LAO sets seller price, LAB sets buyer price
The default auction_type is 5, where the marginal block (offer or bid)
sets the price. The default lim sets no offer/bid or price limits. The
default previous commitment status u0 is all ones (assume everything was
running) and the default duration t is 1 hour. The results may
optionally be printed to a file (appended if the file exists) whose name
is given in FNAME (in addition to printing to STDOUT). Optionally
returns the final values of the solved case in results, the cleared
offers and bids in CO and CB, the objective function value F, the old
style DISPATCH matrix, the convergence status of the OPF in SUCCESS, and
the elapsed time ET. If a name is given in SOLVEDCASE, the solved case
will be written to a case file in MATPOWER format with the specified
name.
