Since the power flow and optimal power flow problems implemented in MATPOWER are for a static problem, they do not make use of the ramp rate data at all, as you have correctly observed. If you want to run experiments that take them into account you will have to define your own problem and implement your own solution algorithm. MATPOWER could potentially be useful as a building block.
