Unit Commitment Models with Power Variables

ABSTRACT
Traditional Unit Commitment models either do not consider ramp-rate constraints for thermal units or make the hypothesis that the power can be instantaneously adjusted. These assumptions greatly simplify the model. Indeed the energy produced in each hour is equal to the power level multiplied by 1 h, and thus energy and power can be represented by the same variable. In this paper we present two new Mixed-Integer Quadratic Programming models where the variables are associated with the power levels, that are assumed to change linearly in each time period, while the energy levels are then computed accordingly. This enables us to derive a more realistic model that can represent more effectively the constraints imposed on the units in order to avoid mechanical stresses to the rotors and can avoid the use of more units in peak hours.
