Although stochastic commitment policies provide robust and efficient solutions, they have high computational costs. This letter considers two modeling approaches for the reduction of their computational effort: the relaxation of the integrality constraint of fast-start units, and the modeling of generation outages as load increments. These approaches are shown to reduce the computational cost while maintaining the good properties of stochastic policies.
