An optimization model has been developed to maximize releases for supplemental power generation in a pump-storage system. The model was developed to aid in the scheduling of pump-storage operations at two facilities of the California State Water Project (SWP). The model allows a base operation of pumping and/or generating to be scheduled at the plant for a given study length (e. g. , a week). This study is then broken down into on-peak/off-peak time periods. To determine the maximum quantity and optimal distribution of releases for supplemental power generation, the model represents the pump-storage system as a flow network to be solved using a network flow programming algorithm. The model is a low-cost, easy to use, and highly effective means of determining an optimal schedule of releases and return pumping in a pump-storage system, in order to maximize the amount of releases for supplemental power generation.
