I may have been confused about what you were trying to accomplish. I thought you had a single OPF problem, where your decision variables are voltages and generator injections, and you wanted to optimize two objectives, losses and social welfare. That's a single optimization problem with multiple objectives.
Now it sounds like maybe you were referring to a multi-level optimization problem where an inner loop solves an OPF (maximize social welfare using voltages and generator injections) and an outer loop (minimize loss, maximize NPV or DG dev profits) where there is some sort of investment decision variable or something. If this is the case, you should be able to use MATPOWER to solve the inner loop, but you'll have to come up with your own algorithm to solve the outer loop. -- Ray Zimmerman Senior Research Associate 419A Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Dec 12, 2012, at 1:30 PM, Carlos Gonzalez Almeida <[email protected]> wrote: > Thanks.
