Abstract

Since the operation of the Middle Route of the South-to-North Water Diversion Project, numerous changes have occurred in the operational conditions of the Danjiangkou Reservoir, among which the ecological assessment requirements for the lower reaches of the Han River have had the most significant impact on the operation mode of the Danjiangkou Power Plant. This paper establishes a short-term scheduling model and formulates differentiated cascade reservoir scheduling objective functions based on various ecological assessment requirements for the downstream river channels, thereby deriving the daily operation process of the Danjiangkou-Wangfuzhou Reservoir under different operating conditions. The conclusions indicate that the establishment of ecological assessment requirements has weakened the peak shaving capacity of the Danjiangkou Reservoir. However, by leveraging the counter-regulation function of the Wangfuzhou Reservoir, the peak shaving capacity of the Danjiangkou Power Plant within the power grid can be restored. Furthermore, as the canalization process of the lower reaches of the Han River progresses, the Wangfuzhou Reservoir will fully exploit its power generation benefits, and the power generation losses incurred due to its coordination with the peak shaving of the Danjiangkou Reservoir will be compensated. The restoration of the peak shaving capacity of cascade reservoirs facilitates their collaboration with other clean energy sources in undertaking power generation tasks at different times within the power grid, thereby providing favorable support for the multi-energy complementary joint operation of the power grid.
