Optimization of Hydroelectric Power Generation in the Pacific NW

 

With over half of the power in the Pacific Northwest coming from hydroelectric sources and with the limitation that only 30 percent of the annual river flow volume can be stored, optimal planning of water usage is crucial. A previous class at the University of Portland developed a hourly scheduler of a hydro system based on an iterative use of a MILP using Xpress-Mosel. The system contains forty dams, all of which are on the Columbia and Snake rivers and their tributaries. In this study we improved the starting point of the model iterative variables to reduce the number of iterations needed for accurate optimization. Additional constraints were added to the model to incorporate and update constraints on the Pacific Northwest hydroelectric system.
