Strategic Unit Commitment for Generation Companies in Deregulated Electricity Markets (original) (raw)

1999

Abstract

In this chapter the new short-term problems that are faced by a generation company in a deregulated electricity market are addressed and a complete decision procedure is proposed. Additionally, a strategic unit commitment model, which deals with the weekly operation of the firm's generating facilities is presented. The traditional cost evaluation techniques and the technical constraints that grant a feasible schedule have been combined with new market modeling equations. Strategic constraints, that allow the accomplishment of the firm's medium term objectives, are suggested. The model is formulated as a MIP optimization problem and is solved by means of a commercial algorithm instead of using the traditional Lagrangian Relaxation approach. Results of the application of the method to a numerical example are presented. The procedure is as simplified version of one of the several tools currently used by a leading Spanish generation company, Iberdrola, for the weekly operation...
