Powel Sim is the main program for short-term hydropower planning within the Powel Smart Generation family. Powel Sim calculates the short-term consequences of given plans in a hydropower system, with given inflow forecasts. Powel Sim serves as the user interface for short-term optimization with Powel Shop, and the optimization
results may be used as initial plans for the daily operative planning.  Powel Sim may also be used for long-term simulations, based on historical inflow and reservoir rule curves or repeating plans.
