SEASONAL-SCALE OPTIMIZATION OF CONVENTIONAL HYDROPOWER OPERATIONS IN THE UPPER COLORADO BASIN

摘要

This study applies HydroSCOPE to the Aspinall Unit, a three-reservoir system in the Upper Colorado River Basin, to illustrate and test the application of a multi-objective reservoir operations optimization model. HydroSCOPE is a systems-level hydropower simulation and optimization tool that couples a water quality model of reservoir and river systems with optimization software to perform tradeoff analysis for seasonal-scale hydropower operations. A multi-objective optimization strategy is used to explore operational approaches that improve both revenue generation and environmental goals, while a single-objective optimization capability makes the tool integrable with short-term planning models. HydroSCOPE is being developed as part of the DOE funded Water Use Optimization Project, which incorporates streamflow forecasting, environmental performance indicators, and day-ahead and seasonal scale planning to facilitate more efficient water use, power and ancillary services generation, and environmental performance in conventional hydropower systems.
