MATPOWER only solves OPF problems with continuous variables. I believe that minimum control changes is implicitly a discrete variable problem. A possibly related continuous variable problem would be to minimize the change in dispatch from a given dispatch point. This can be accomplished by shifting the portion of the each cost curve to the right of the dispatch point up by some amount (an incremental cost) and the portion to the left down by some amount (a decremental cost).
