SHORT-TERM HYDROTHERMAL SCHEDULING .1. SIMULATED ANNEALING APPROACH

The paper develops a short-term hydrothermal scheduling algorithm base d on the simulated annealing technique. In the algorithm, the power ba lance constraint, total water discharge constraint, reservoir volume l imits and constraints on the operation limits of the hydrothermal gene rator and the thermal generator are fully accounted for. The relative operation capacities of the hydroplant and the thermal plant is also c onsidered. A relaxation method for checking the limits is proposed and included in the algorithm. The performance of the algorithm is demons trated through a test example.
