I’m not sure what you mean by “completely non-convex”, but yes, you can use
LAM_P as the LMP. It is simply the sensitivity of overall objective function to
a change in the load at the bus. Of course this is at the OPF solution, which
in a non-convex problem is not guaranteed to be a global solution.
