Computation of spot prices and congestion costs in large interconnected power systems

摘要

Foremost among the new paradigms for the U.S. utility industry is the "poolco" concept proposed by Prof. William W.Hogan of Harvard University ~(1). This concept uses a central pool or power exchange in which physical power is traded based on "spot" prices or market clearning prices. The rapid and accurate calculation of these "spot" rpices and associated "congestion costs" for large interconnected power systems is the central tenet upon which the "poolco" concept is based.
