| Description: | Maximum change in flow (MW or cumecs per hour) |
Waterway Max Ramp is the maximum change in flow (MW or cumecs per hour). To correctly enforce the constraint in the initial (t=0) period of a chronological simulation (e.g.ST Schedule) you should also define Initial Flow. In the absence of this definition the t=0 ramp constraint is relaxed. This constraint can be made a soft constraint with the Max Ramp Penalty property.
