Decomposition approaches for block-structured chance-constrained programs with application to hydro-thermal unit commitment

Ackooij, Wim - In: Mathematical Methods of Operations Research 80 (2014) 3, pp. 227-253

<Para ID="Par1">The unit commitment problem, aims at computing the production schedule that satisfies the offer … numerical instances. The latter decomposition procedures are clearly a prerequisite if robust unit commitment is ever to be used … schedule. The obtained results are illustrated on a convex simplification of a unit commitment problem in order to avoid the …
