Abstract
With continuous access of photovoltaic power stations to hydropower stations in the river basin and packaged electricity delivery to grid together,the optimal scheduling of hydro-solar complementation puts forward new requirements for the scheduling of existing cascade hydropower stations in the basin.In order to solve the practical operation problem that the existing medium-and long-term optimal hydropower scheduling rules cannot effectively avoid the risk of power abandonment in short-term hydro-solar complementary joint operation,the hydro-solar complementation of Xiaowan and Manwan hydropower stations on Lancang River basin is taken as the example to study the short-term power abandonment risk.In the study,the long-term hydrological data of Xiaowan and Manwan hydropower stations are divided into incoming water frequencies for two various photovoltaic stations capacity scenarios in the near and long term,and the short-term power abandonment risk is quantified and the medium-and long-term hydro-solar complementary optimal scheduling diagram is plotted.It is concluded that the joint scheduling can effectively reduce the power abandonment risk of hydro-solar complementary operation under different incoming water conditions,especially in the normal year with abundant water.Study can provide a reference for the formulation of actual scheduling rules.关键词
