A tight MIP formulation of the unit commitment problem with start-up and shut-down constraints

Gentile, C.; Morales España, German Andres; Ramos Galán, Andrés (01/03/2017)

This paper provides the convex hull description of the single thermal Unit Commitment (UC) problem with the following basic operating constraints: (1) generation limits, (2) start-up and shut-down capabilities, and (3) ...

An MIP formulation for joint market-clearing of energy and reserves based on ramp scheduling

Morales España, German Andres; Ramos Galán, Andrés; García González, Javier (Association des Economistes de l'Energie (París, Francia), 04/06/2015)

The day-ahead unit-commitment (UC)-based marketclearing (MC) is widely acknowledged to be the most economically efficient mechanism for scheduling resources in power systems. In conventional UC problems, power schedules ...
