Methods for Deriving Operating Rule Curves for Multiple Reservoir Systems

摘要

Studies undertaken examined procedures to improve the efficiency with which reservoir systems are operated and to improve the tools for studying such systems. Three risk-based criteria (reliability, resiliency and vulnerability) for describing reservoir-system operation were developed. These criteria illustrated the sensitivity of a reservoir system's performance to the objective function employed to derive its operating policy. Several families of multi-reservoir screening models were examined. Models based on mean-monthly flows performed very poorly as did linear-decision-rule (LDR) chance constrained models. A sequential linear programming (SLP) approach always found the optimal solution in somewhat less time. A new optimal control algorithm was faster than the SLP procedure but is difficult to implement.
