RESERVOIR OPERATING POLICIES CONSIDERING RELEASE CHANGE

Optimization models have been used in reservoir management problems to facilitate the satisfaction of various demands. One frequently ignored problem is the reservoir operation quality. The resulting operation curves may have sharp changes in the storage level of the reservoir or in the release to the downstream channel, which has potentially negative impact on the quality of reservoir operation. A Goal Programming model involving a min-max objective has been developed herein to determine operating policies, which attempts to remedy such problems. The results show a significant improvement in the reservoir operation.
