黄河上游玛尔挡-班多-羊曲梯级水电站联合调度效益分析
Benefit analysis of the coordinated operation of Ma'erdang-Banduo-Yangqu cascaded hydropower stations on the upper Yellow River
摘要
Abstract
The upper Yellow River is one of the thirteen major hydropower bases in China,playing an important role in the energy structure of Qinghai and the Northwest Power Grid.More than ten hydropower stations have been planned for the upper Yellow River upstream of the Longyangxia reservoir,but at present only Banduo hydropower station has its full unit connected to the grid.Recently,great progress has been made in the Ma'erdang and Yangqu hydropower stations under construction.The Ma'erdang Hydropower Station and Yangqu hydropower station,located near the existing Banduo hydropower station,exhibit strong hydraulic and electrical correlations,thereby presenting the potential for coordinated operation among the three hydropower stations.However,a coordinated operation rule for the Ma'erdang-Banduo-Yangqu Cascaded hydropower stations remains absent,resulting in a significant potential for enhancing scheduling efficiency. This study establishes a dual-objective optimization model aimed at maximizing power generation and maximizing minimum output,and carried out a long series and multi-scenario solution analysis to explore and compare the efficiency improvement space between independent operation of Ma'erdang hydropower station and coordinated operation of Ma'erdang-Banduo-Yangqu Cascaded hydropower stations. The results indicate that:(1)There is an obvious trade-off between annual mean power generation and guaranteed output,where an increase in guaranteed output reduces generation efficiency and guarantee rate.For Ma'erdang hydropower station under independent operation,increasing the guaranteed output from 200,000 kW to 700,000 kW reduces its annual mean power generation from 7,452 million kW·h to 7,250 million kW·h,with the guarantee rate dropping from 100％ to 62.1％.Under coordinated operation of the Ma'erdang-Banduo-Yangqu cascade,the guaranteed output increases from 474,100 kW to 974,100 kW,while the annual mean power generation of the cascade declines from 13,863 million kW·h to 13,706 million kW·h,and the corresponding guarantee rate drops from 100％ to 78.2％.(2)Compared with the independent operation of Ma'erdang,the coordinated operation of the Ma'erdang-Banduo-Yangqu cascade shows greater potential to enhance efficiency.This is reflected in a decrease in Ma'erdang's annual mean power generation,alongside increase for Banduo,Yangqu,and the entire cascade.In the coordinated operation scenario with guaranteed minimum output,the cascade's annual mean power generation is maximized,with an increase of 358 million kW·h compared to independent operation.Specifically,the annual mean power generation in Ma'erdang decreases by 79 million kW·h,while Banduo and Yangqu increases by 112 million kW·h and 325 million kW·h,respectively.Additionally,the total annual mean reduction in non-power release for the cascade is 196 million m3.(3)Coordinated operation significantly enhances the stability and reliability of cascade power supply compared with independent operation,thereby providing a strong guarantee for new energy consumption under multi-energy complementary scenarios.In terms of corresponding guaranteed output scenarios,the guarantee rate for the cascaded hydropower stations under coordinated operation is higher than that of the Ma'erdang hydropower station under independent operation.(4)Considering the power generation,non-power release,guaranteed output and guarantee rate,the coordinated operation scenario recommended in this study is the guaranteed output of the cascade system of 674,100 kW(guarantee rate of 96.1％).Under this scenario,the annual mean power generation of the cascade system is 13,777 million kW·h,with an increase of 394 million kW·h in power generation and a reduction of 0.97 billion m3 in total non-power release compared to independent operation. These research findings can serve as valuable references for future coordinated operation and benefit compensation of Ma'erdang-Banduo-Yangqu cascaded hydropower stations.关键词
