Abstract	This paper is concerned with the representation of price-responsive loads in the short term coordination of predominantly hydroelectric hydrothermal systems. The proposed approach allows the representation of cross- relationships between demand and price during different dispatch intervals of a given time horizon. Also, consumer energy constraints which behave as dynamic restrictions can be taken into account. By that means, a load shifting program in which the consumers' overall energy consumption remains constant throughout the time horizon can be simulated. The short term hydrothermal coordination is solved as a single optimization problem employing the primal-dual interior point method. A 32- bus equivalent system of the Southern Brazil Interconnected Power System is used to illustrate the effect of price-responsive loads on reservoir storages.
