Long-Term Optimal Scheduling of Cascade Hydropower Plants in the Primary Market: The Wujiang River Case
Publication: World Environmental and Water Resources Congress 2018: International Perspectives, History and Heritage, Emerging Technologies, and Student Papers
ABSTRACT
As the further development of market-oriented power system reform in southwest China, hydropower system in the regions where electricity market reform has not been developed must be prepared for the upcoming market environment. This study analyses the primary market environment of Wujiang hydropower system, which determine the year-end energy storage solutions, for long-term optimal scheduling. Scheduling of Wujiang cascade hydropower plants pursue two goals: one is to realize the coordinated and stable operation of hydro-thermal system, another is to maximize the revenue of hydropower system. In this paper, a long-term optimal scheduling model of cascade hydropower plants with generation rights trading is proposed. The model achieves maximum comprehensive revenue by optimizing the power generation revenue and the energy storage revenue at the end of the planning horizon. The proposed model is applied to the operations of Wujiang cascade hydropower plants, and the properties of the model are also discussed.
