MATPOWER does not include ramp rate in power flow analysis. Power flow finds a 
steady state solution, whereas ramp rate has to do with changes in solution 
through time (e.g. limiting differences between two steady state solutions). So 
I don't really think ramp rate is relevant to the traditional power flow 
problem.
