Thank you so much for tthe help. I think the problem is because I am using lossless DCOPF and the change in my hourly load profile is not that much, so the sensitivity of LMP to laod change will be zero. I replaced (rundcopf) by (runopf) to perform ACOPF. Also, I changed (OPF_ALG_DC) to (OPF_ALG), but I got the following error:
??? Error using ==> makeAvl at 73 makeAvl: either Qmin or Qmax must be equal to zero for each dispatchable load. Error in ==> opf_setup at 172 [Avl, lvl, uvl] = makeAvl(baseMVA, gen); Error in ==> opf at 219 om = opf_setup(mpc, mpopt); Error in ==> runopf at 96 [r, success] = opf(casedata, mpopt); Error in ==> run_3bus at 120 results = runopf(mpc, opt); What this error means? What should I do else to have a correct ACOPF? Thanks again, appreciate your help. ----- Original Message ----- From: sarab singh <[email protected]> Date: Monday, September 16, 2013 10:42 pm Subject: Re: Question about locational marginal prices To: MATPOWER discussion forum <[email protected]> > It may happens when the network is not in congestion. > > > > From: Haneen Mohammad dawoud Aburub <[email protected]> > To: [email protected] > Sent: Monday, 16 September 2013 10:54 PM > Subject: Question about locational marginal prices > > Hi, > > I used the DCOPF to get the locational marginal prices of a 3-bust system. > The locational marginal prices that I have got are not changing with the > change in load.
