Transmission congestion management in an electricity market

Managing transmission congestion in an unbundled electric power system pose s a challenge to an Independent System Operator (ISO). This paper considers an open transmission dispatch environment in which pool and bilateral/mult ilateral 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 coordinati on between market participants to achieve additional economic advantages is described.
