Carlos, I'm not sure what you mean by "test the example ... regarding zero power factor". If you are going to change some of the existing dispatchable loads to have a zero power factor, then the existing market structure for the example, which includes only $/MW bids for active power, will not be applicable. So you need to decide how you want to handle these reactive-only loads. I suppose you'll need to specify reactive power bids for them.
On your second question, the offers and bids are used to construct a gencost matrix with negative costs for the negative generators that represent dispatchable loads. The objective function is then to minimize this "cost" of generation, which is computed in opf_costfcn.m. You are correct that this is equivalent to maximizing social welfare. -- Ray Zimmerman Senior Research Associate 211 Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Mar 8, 2011, at 5:04 PM, Carlos Gonzalez Almeida wrote: > Dear Dr. Zimmerman > > -Could you please test the example provided in the manual (t_auction_case) > regarding zero power factor.
