Automated Real-Time Hydropower Scheduling for Lower Colorado River, Texas
Publication: Watershed Management and Operations Management 2000
Abstract
A major water and energy provider in Central Texas is the Lower Colorado River Authority (LCRA). It supplies water and electricity to over a million persons. Approximately 10 percent of that electricity is generated from hydroelectric power plants on the six dams in the Highland Lakes system on the lower Colorado River. A real-time scheduling system has been developed and is being implemented into the LCRA Energy Management System (EMS) to optimally schedule the hourly operation of thirteen hydropower generating units in concert with the three steam-electric power stations operated by the LCRA. The hydro scheduling system uses a mixed integer linear programming (MILP) model of the Highland Lakes to determine the optimal hydro generation based on forecasted power and water demands and hydrologic conditions over the next 72 hours. The MILP model maximizes hydropower generation while satisfying hourly and daily constraints on generation capacity, lake storage and flow releases. The solution to the scheduling model is provided in real-time to the EMS which uses the results to determine generation unit commitment in the LCRA power system.
