function [pcost, qcost] = pqcost(gencost, ng, on) %PQCOST Splits the gencost variable into two pieces if costs are given for Qg. % [pcost, qcost] = pqcost(gencost, ng, on) checks whether gencost has cost % information for reactive power generation (rows ng+1 to 2*ng). If so it % returns the first ng rows in pcost and the last ng rows in qcost. % Otherwise, leaves qcost empty. Also does some error checking. % If on is specified (list of indices of generators which are on line) % it only returns the rows corresponding to these generators. % MATPOWER Version 2.0 % by Ray Zimmerman, PSERC Cornell 9/19/97 % Copyright (c) 1997 by Power System Engineering Research Center (PSERC) % See http://www.pserc.cornell.edu/ for more info. if nargin < 3 on = [1:ng]'; end if size(gencost, 1) == ng pcost = gencost(on, :); qcost = []; elseif size(gencost, 1) == 2 * ng pcost = gencost(on, :); qcost = gencost(on+ng, :); else error('gencost has wrong number of rows'); end return;
