Modeling a Level Power Reservoir
Steps to follow in setting up a level power reservoir for optimization
1. Set up a running simulation model, using methods that are compatible with optimization for Power, Tailwater, Spill, and so on.
2. Chose an Optimization Power method.
3. Choose an Optimization Head Computation method. In Optimization, None must be chosen.
4. Select the Optimization Spill method corresponding to the method selected in the Spill category.
5. Fill in the LP Param tables related to Power, Turbine Capacity and Best Turbine Flow (if plant power is used). Alternatively, the Power Linearization Automation method can also be chosen to automatically determine the values for the LP Param tables.
6. Select the Optimization Tailwater method corresponding to the method selected in Tailwater category. If Opt Base Value Plus Lookup Table or Opt Stage Flow Lookup Table is selected, fill in the Tailwater Elevation LP Param table. Alternatively, select a Tailwater Linearization Automation method (Range Input Automation is currently available).
7. If future value is needed, select a method in the Future Value category, followed by the Optimization Future Value category, and if desired, Cumul Stor Val Linearization Automation.
8. Selection of the remaining methods and linearizations can be done in any order. Pool elevation linearizations, Pool Elevation Linearization Automation, Evaporation and Precipitation, Optimize Evaporation Computation, Evaporation Linearization Automations, Bank Storage, Hydrologic Inflow, Energy In Storage, and Diversion from Reservoir. The appropriate data must be entered for each method.
