NONLINEAR APPROACH TO THE DETERMINATION OF RESERVOIR OPERATING RULES (WATER, SYSTEMS, PROGRAMMING, MATHEMATICAL)
Abstract
A new approach to the determination of reservoir operating rules is presented. The implicitly stochastic optimization technique is modified by the formulation of a deterministic nonlinear program incorporating the operating rule as target release bounded constraints. The methodology is developed to minimize losses associated with non-attainment of specified demands or targets in terms of releases or releases and storages. In the problem formulation, operating rules or release rules are expressed as functions of storages and inflows. Different pairs of loss functions and release rule forms are considered to illustrate the versatility of the new approach. Results show that the new methodology provides more information and generates operating rules that are better than or comparable to those obtained from methodologies originally based on dynamic programming. An indication is given on how the method can be applied to multireservoir systems.
