Transmission congestion management in an electricity market

Abstract

Managing transmission congestion in an unbundled electric power system poses a challenge to an independent system operator (ISO). This paper considers an open transmission dispatch environment in which pool and bilateral/multilateral dispatches coexist and proceeds to develop a congestion management strategy for this scenario. Prioritization of electricity transactions and related curtailment strategies are explored and a mechanism for coordination between market participants to achieve additional economic advantages is described.
