In reservoir operation, optimal release is determined with time period. Hydropower generation is one of the major activity for which the releases from a reservoir are used. Reservoir operation can be achieved in two ways, standard operating policy and optimal operating policy. In this study, a mathematical model has been developed using nonlinear programming for determining optimal reservoir release with maximizing the generated hydropower. Equations representing the continuity, release, storage, head, water elevation and the turbine characteristics have been imposed as constraints in the optimization model. The solution of the developed model provides generated hydropower and optimal reservoir releases. Applicability of the developed optimization model has been illustrated for the reservoir created by Tehri dam in Uttarakhand. The effect of the turbine characteristics has been investigated in the optimal generation of hydropower. The optimal reservoir release and generated hydropower were obtained for ten years as the desired output. From the results, it is inferred that the generated hydropower is more for the same value of release when turbine characteristics are considered.ennullThesis
