The High-Elevation Hydropower System In California Is Composed Of More Than 150 Hydropower Plants. The Expected Shift Of Runoff Peak From Spring To Winter As A Result Of Climate Warming, Resulting In Snowpack Reduction And Earlier Snowmelt, Might Have Important Effects On Hydropower Operations. Estimation Of Climate Warming Effects On Such A Large System By Conventional Simulation Or Optimization Methods Would Be Tedious And Expensive. Employing Optimization And Cooperative Game Theory Methods, This Book Presents A Novel Approach For Modeling Large Hydropower Systems And Deriving Climate Change Adaptation Strategies For California.
