Scheduling Day-Ahead Generation with Enhanced Hydro Constraints

Efficiently integrating hydropower scheduling into system-level generation planning is important for reaching the 100% clean energy goal. We introduce hydro-related constraints to unit commitment problems to enhance hydropower representation in day-ahead generation scheduling. The constraints are intended to capture hydro related conditions such as flow rate, hydro-power conversion, limits on flow fluctuation, reservoir operation, and balance of instreams among different river sites.

The resulting hydro enhanced unit commitment problem can be solved as a mixed-integer programming model. We will discuss the importance of adding these hydro-related constraints by illustrating the impact of these constraints on generation scheduling in regional day-ahead electricity planning.
