Moreover, operating conditions and units availability are also in constant evolu-tion. The selection of the best produc-tion configuration is then a difficult task if the hydraulic circuit head losses and the turbine hill-charts non-linearities are also considered. Thus, simple optimization tool can significantly help to improve a power plant annual production.OptiPower: Hydropower Generation Optimization ToolOptiPower is a custom designed software divided in two parts:- 1) calculator: to select the best operating set points of a hydroelec-tric power plant according to opera-ting constrains;- 2) forecast: to optimize power generation strategy over 24/48/72 hours.OptiPower includes a model of the power plant taking into account: - custom hydropower plant layout; - hydraulic non-linear head losses; - turbine efficiency hill-charts; - upstream/downstream water levels;- power and/or guide vanes set Power Vision EngineeringOptiPower enables to de?ne best operating set points of a power plant in order to maximize the power generation and global e?ciency according to real-time operating conditions, constrains and demand.OptiPower 1.0Operating Conditions:- Upstream / Downstrem water levelsOperating Strategy:- Operating Units- Power levels or GVOPower Plant Data:- Hydraulic Circuit Layout- Losses Coefficients- Turbine CharacteristicsOperating Parameters:- Power- Discharge- Guide vane Openings- EfficencyOPTIMUM ?ENDCalculatorCustom-designedpower optimization toolyesnoOptiPowerOptiPowerOptiPower enables to test and thus optimize power generation scenarios taking into account: - reservoir inflow forecasts; - reservoir geometry; - power generation scenarios with power or guide vanes set points; - hydraulic circuit model inclu ding head losses, turbine efficiency hill- charts, operating units; - surge tanks mass oscillations; - energy hourly price.For each scenario, OptiPower provides: - the energy production history in MWh; - the power production profile; - the time evolution of the efficiency of each unit; - the global operation efficiency given by: - the turbine transients (without waterhammer effects); - the surge tank transient; - the overall total discharge during 24/48/72 hours; - the time evolution of the reservoir water levels.OptiPower can also be interfaced with: - energy market price database; - flood prediction tools; - maintenance costs database.By iterative process, the user can: - optimize the production; - define optimal operating strategy; - optimize water flows; - minimize spillway discharge; - reduce maintenance costs; with reliable power plant model.OptiPower enables to test power generation scenarios over 24/48/72 hours, in order to ?nd the best opera-ting strategy according to upstream/downstream in?ows forecast, units availability and demand forecast.
