very grateful for the nice explanation. however, in the objective function of the dual LP (slide 9), i think it should have added the part of lambda to be like ( -b transpose*v+ beq transpose*lambda))??? Anyone can agree with me??
The problem described in the video lecture indeed allows to get both the dispatch and the price. The dispatch is given by the primal solution of the optimization problem, and the price by the dual variable associates with the equality constraint (balance equation).
