Power Auctions and Intertemporal Production Costs: Dealing with Unit Commitment

Bart McGuire

How should generators (‘units’) with different energy costs, different miniumum and maximum levels of operation, and different start-up costs be assigned to satisfy a time profile of electricity demand? In PWP-054, two very simple models of this "unit commitment problem" are studied - both in the context of uncertainty about future demand.  The preliminary objective of McGuire’s analysis is to find optimal commitment strategies for the manager of a system of generators.  The main objective is to suggest models of power-generation technology sufficiently simple to make possible the exploration of efficient power-auction design.  Small steps toward both goals are described.
