| 1 | 水库群优化调度中的结构分析方法研究进展显示文摘在我国水库群规模日益庞大、功能结构日益复杂化的背景下,结构分析方法在水库群优化调度模型求解中占据越来越重要的地位。为全面梳理不同结构分析方法的适用性和优劣性,以及为复杂结构水库群优化调度提供高效的结构分析方法,基于水库群优化调度60余年来的研究成果,分别阐述了顺序模拟法、蓄供水判别式法、效用均衡理论法、聚合-分解法和水力关联矩阵法5种结构分析方法的研究进展。顺序模拟法逻辑直观、普适性强,蓄供水判别式法能够对发电调度中水库群的蓄供水次序快速排序,以上2种方法均适宜于串联结构水库群结构分析;效用均衡理论基于微观经济学厂商均衡理论对水库群调度方式进行优化,理论基础坚实,适用于水力关系较为独立的并联水库群;聚合-分解法包含水库群联合调度图和大系统分解协调2种形式,可与其他串并联结构分析方法联合使用,适用于大规模混联结构水库群;水力关联矩阵法则采用矩阵形式描述水库群内部两两之间关系,不受水库群结构组合的限制,因此适用于任何结构水库群。结构分析方法对于优化高效求解水库群优化调度问题至关重要,但也需要与其他环节配合才能实现,建议未来在径流预报信息利用、优化调度统计模型与物理背景耦合及混联水库群精细化调度等方向开展进一步研究。 | 周婷 戚王月 金菊良 | 2020 | 长江科学院院报2020，37，12： | 7 |
| 2 | Simulation-optimization model of reservoir operation based on target storage curves显示文摘This paper proposes a new storage allocation rule based on target storage curves. Joint operating rules are also proposed to solve the operation problems of a multi-reservoir system with joint demands and water transfer-supply projects. The joint operating rules include a water diversion rule to determine the amount of diverted water in a period, a hedging rule based on an aggregated reservoir to determine the total release from the system, and a storage allocation rule to specify the release from each reservoir. A simulation-optimization model was established to optimize the key points of the water diversion curves, the hedging rule curves, and the target storage curves using the improved particle swarm optimization(IPSO) algorithm. The multi-reservoir water supply system located in Liaoning Province, China, including a water transfer-supply project, was employed as a case study to verify the effectiveness of the proposed join operating rules and target storage curves. The results indicate that the proposed operating rules are suitable for the complex system. The storage allocation rule based on target storage curves shows an improved performance with regard to system storage distribution. | Hong-bin FANG Tie-song HU Xiang ZENG Feng-yan WU | 2014 | Water Science and Engineering2014，7，4： | 0 |
