Re: formula of LMP in ac mode

[Carlos E Murillo-Sanchez]

No formula is used; it comes directly from the optimizer algorithm, which is trying to solve the first order optimality conditions of the optimization problem.  These conditions include the Lagrange multipliers for the power balance equations and that's where the LMPs come from.  Yahook K wrote: Dear Matpower users, I calculate the locational marginal price in ac mode using runofp function. But I am still not clear the formula you use in AC mode to calculate the price. Can you shed the light on me? Thanks.
