Question

[pourahmadi_f]

Hi,

I want to run an AC optimal power flow with fixed zonal reserves and
co-optimize reserves and energy via using MATPOWER5.1. RUNOPF_W_RES. I
have a question about obtaining locational marginal price (LMP).
As this problem used in MATOPWER is completely non-convex, is it valid to
take Lagrangian from the non-convex problem?


In user's manual, it is stated that Lam_P is Lagrange multiplier on
real power mismatch.
Can I use Lam_P as LMP?

I would appreciate if you help me.

Best Regards
