Optimal Daily Operation of Cascade Hydropower Stations
Abstract: Daily operation models for cascade hydropower stations were proposed and developed in this paper. The dynamic programming (DP) was used to solve daily optimal operation for two deterministic models with the goal of maximizing the hydropower generation and minimizing turbine discharge of the cascade hydropower stations, respectively. The inflow (from July to December in 2013) and corresponding real-time hydropower record data were used. The optimal result showed that hydropower generation can be increased from 0.581 billion kW•h to 0.648 billion kW•h (or an increase 11.54%) and turbine discharge of the cascade hydropower stations can be decreased from 2.92 billion m3 to 2.89 billion m3 (or a decrease of 0.89%) compared with current operation method. The assurance rate of firm output can be increased from 92% to 100%.
