This is a solver issue. See footnote 5 on page 10 of the MOST User’s Manual
<http://www.pserc.cornell.edu/matpower/docs/MOST-manual-1.0.pdf>. For MIQP
problems, that is, unit commitment problems with quadratic generator costs
and/or ramping wear and tear costs, you will need Gurobi, CPLEX or MOSEK. I
recommend Gurobi.
