Abstract
Some models for the economic dispatch of electric power are introduced and treated by mathematical programming techniques. In particular, our presentation includes (i) a short-term model for the optimal dispatch of thermal units, which is solved by a specific path following method, (ii) a daily model for a generation system consisting of thermal units, pumped storage plants and an energy contract, which can be solved by standard convex quadratic programming algorithms, and (iii) two stochastic programming models for the optimal daily dispatch, which depend on the (unknown) probability distribution of the electric power demand. One of the latter models can be solved efficiently by combining nonparametric estimation procedures and convex programming methods.
Zusammenfassung
In der Arbeit werden einige Modelle zur optimalen Lastverteilung von Elektroenergie diskutiert und mit Hilfe von Optimierungsmethoden behandelt. Insbesondere gehen wir ein auf (i) ein Modell der Momentan-Optimierung der Lastverteilung von Wärmerkraftwerden, das mit einer speziellen parametrischen Optimierungsmethode gelöst wird, (ii) ein Tagesmodell für ein Erzeugersystem bestehend aus Wärmekraftwerken, Pumpspeicherwerken und einem Energievertrag, welches mit Standardmethoden der quadratischen konvexen Optimierung behandelt wird, und (iii) zwei stochastische Optimierungsmodelle für die Optimierung im Tagesbereich, welche von der (unbekannten) Wahrscheinlichkeitsverteilung des Elektroenergiebedarfs abhängen. Eines dieser Modelle kann durch die Kombination nichtparametrischer Schätzmethoden mit Verfahren der konvexen Optimierung effizient numerisch behandelt werden.
