A MILP approach to the short term hydrothermal self-scheduling problem

This paper addresses the hydrothermal electricity producer self-scheduling problem in day-ahead energy and reserves markets. A 0/1 mixed integer linear formulation of the producer self-scheduling problem is presented, which allows a realistic modeling of the unit´s operating phases (synchronization, soak, dispatchable, desynchronization). Prohibited operating zones and daily hydro energy production constraints are also modeled. Test results address the effect of the energy and reserves market clearing prices on the producer units´ day-ahead commitment status and profits.
