Abstract :
This work describes studies concerning the impact of operational limits on the total transfer capacity and transmission costs of systems under pool-bilateral markets. These studies are made via an optimal power dispatch model that, using the superposition principle (SP), represents each transaction and the power traded at spot market by an individual set of network equations. Results are presented for a 5-bus system and a 182-bus equivalent of the Brazilian southern region system.
