Research on Various Operation Modes of Geheyan Hydropower Station Reservoir in the Qingjiang River

Abstract:

According to the characteristics and main task of the Geheyan hydropower station reservoir in the Qingjiang River, the problem of how to use reservoir storage capacity to cope with the contradictions between the flood control and power generation, reliability and economy of hydropower station, the supply and demand of power when runoff cannot be accurately forecasted. Aiming at these problems, various operation modes of Geheyan hydropower station are presented in this paper. In order to pursue maximizing generation benefit, considering both hydro condition and adjust peak requirement of power system, the expected benefit as the objective function is presented. Comparisons are conducted for three various operation modes. The results show that dynamic programming successive approximations (DPSA) is better than other algorithms, whose average annual generation and generating guarantee rate increase obviously compared to the effects of other algorithms.
