PURPOSE ^

RUNMKT Runs smart market for PowerWeb.

SYNOPSIS ^

function [MVAbase, cq, cp, bus, gen, gencost, branch, f, dispatch, success, et] =runmkt(casedata, q, p, mkt, max_p, u0, t, mpopt, fname, solvedcase)

DESCRIPTION ^

RUNMKT  Runs smart market for PowerWeb.

   Deprecated, see RUNMARKET.

   [BASEMVA, CQ, CP, BUS, GEN, GENCOST, BRANCH, F, DISPATCH, SUCCESS, ET] = ...
           RUNMKT(CASEDATA, Q, P, MKT, MAX_P, U0, T, MPOPT, FNAME, SOLVEDCASE)

   Computes a new generation schedule from a set of offers and bids,
   where offers and bids are specified by Q and P, MKT tells it what
   type of market to use, MAX_P is the price cap, U0 is a vector
   containing the commitment status of each generator from the previous
   period (for computing startup/shutdown costs), T is the time duration
   of the dispatch period in hours, and MPOPT is a MATPOWER options vector
   (see 'help mpoption' for details). Uses default options if MPOPT is not
   given. The rows in Q and P correspond to the rows in gen and gencost,
   and each column corresponds to another block in the marginal offer or
   bid. The market codes are defined as the sum of the
   following numbers:
        1000                - all markets
         100 * adjust4loc   - adjust4loc = 0 to ignore network,
                              1 to compute locational adjustments via AC OPF,
                              2 to compute them via DC OPF
          10 * auction_type - where the values for auction_type are 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

   If P or Q are empty or not given, they are created from the generator
   cost function. The default market code is 1150, where the marginal
   block (offer or bid) sets the price. The default MAX_P is 500, the
   default 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 BASEMVA,
   CQ, CP, BUS, GEN, GENCOST, BRANCH, F, DISPATCH, SUCCESS, and 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 with a '.m' extension added.
