The California State Water Project (SWP) is operated and managed using state-of-the-art operations research and optimization techniques. Medium- and long-range studies for the operation of the SWP are performed using a simulation/optimization model called NEOSYS. NEOSYS simulates and optimizes the operation of five main SWP reservoirs and produces reports with monthly detail. The electrical schedules for operation of the pumping and generating plants for power sales and purchases are determined using a network flow programming optimization model. A comprehensive large-scale optimization model has been developed to replace the network model and the hydraulic simulation models presently used for operations scheduling. It consists of hydraulic network components to meet storage objectives of all the reservoirs, a linear programming component to determine the schedules at pumping and generating plants, and a network programming component to balance electrical loads and resources within the SWP.
