Short-term hydrothermal scheduling with reservoir volume constraints. I. Simulated annealing approach

This paper develops a short-term hydrothermal scheduling algorithm based on the simulated annealing technique. In the algorithm, the load balance constraint, total water discharge constraint, reservoir volume limits and constraint on the operation limits of the hydrothermal generator and the equivalent thermal generator are fully accounted for. A relaxation method for checking the limits is proposed and included in the algorithm. The performance of the algorithm is demonstrated through an application to a test example. The results are presented and are compared to a conventional method
