Table 1 Factors affecting the efficiency of shipping.
From: Hydropower station scheduling with ship arrival prediction and energy storage
Influence factors | Descriptions |
|---|---|
Discharge flow | In order to meet the navigational conditions, the discharge flow needs to meet a certain range |
Daily water level variation | The power station needs to perform grid peaking, but the downstream flow fluctuates, so the daily change in water level has to meet certain conditions |
Hourly water level variation | Considering the safety of shipping, in addition to the daily variation of water levels, the condition of hourly variation should be satisfied |
Downstream water level change rate | The rate of the changes of downstream water levels shall meet constraints |
Water flow rate | The flow rate of water should meet certain requirements for ship passing |
Downstream flow height | Downstream flow height affects the safety of ship navigation |
