A Practical Short-term Scheduling Model for Cascade Hydropower Reservoirs

To increase power generation of the reservoirs and respond the varying loads in the power grid, a lightweight and practical short-term scheduling model is presented to deal with the short-term hydropower optimal scheduling problem. In this model, a daily load curve shifting strategyis utilized for peak load purpose. Moreover, a new fast unit generation flow distribution strategy considering unit efficiencyis also proposed to optimize the unit power outputs. The proposed method was applied to the cascade hydropower reservoirs in Jinsha River. The experimental results show that the model has a good performance in scheduling the cascade hydropower system.
