摘要：

This paper presents a short term hydrothermal scheduling approach for dominantly hydro systems. The problem modelling takes into account both the hydroelectric system operating and the electric transmission network constraints in detail. It basically consists of a simulation of the hydraulic system with the discharge decisions given by an optimal DC power flow algorithm. The release targets of the reservoirs, established by the long term operational planning, are enforced by a dual Lagrangean approach that fixes a penalty for the use of water in the reservoirs. Two illustrative examples have been solved in order to evaluate the efficiency of the approach.
