A Practical Monthly Optimum Operations Model

A mathematical model is developed for the Central Valley Project. The model produces a 12-month operating policy. The model is programmed in FORTRAN IV for processing on a CDC CYBER 74 computer. Project operations managers use the model as a decision-advising tool. This model will be coupled with a daily strategy mode. A four-dimensional incremental dynamic programming algorithm is developed to optimize the operation of the four-reservoir system. The objective of the model is to maximize energy generation within the limits of firm water and power contracts, mandatory releases, and flood control. A unique technique given the acronym RecIP for recomputed initial policy is developed to compute the initial operating policy that is optimized. The RecIP technique is an iterative process using the results of the incremental dynamic programming algorithm to compute a new initial policy to satisfy the required end of operational period target storages desired by the user.
