Optimization of real-time hourly operations of a complex, multiple purpose reservoir system
An hourly optimization model has been developed for on-line use in the operation of the Central Valley Project (CVP) in California. The procedures which are used for optimization are applicable to other water resource systems, although program details must necessarily be changed. The hourly program is supplemental to monthly and daily optimization programs previously developed by the Principal Investigator and his co-workers for the CVP, and maximizes a weighted summation of generated power over a 24-hour period subject to specified plant releases obtained from a daily program, a desired hourly power schedule, and appropriate system and equipment constraints. The procedure has been developed in two phases. Phase I involves a determination of a good feasible policy (a set of releases) through an iterated linear programming and adjust process. Phase II uses this feasible policy as a starting policy in an incremental dynamic programming, successive approximations process to derive an optimal policy. CVP operational records of some typical days have been compared with the program outputs for these days, and significant improvements are observed, both in better conformance with the desired (Pacific Gas and Electric Co.) power schedule and more efficient hydropower production.
