长江上游大型水电站联合调度,是一个涉及自然科学、工程技术、经济政策和管理法规等多领域、多专业的复杂巨系统。要实现梯级水电站多目标、多任务、多尺度的联合调度,需要强有力的科技支撑。一、尚待研究的基础科学问题1、梯级水电站群多目标联合调度复杂巨系统优化理论。按照规划,2030年长江上游将建成的大型水电站80余座,干支流梯级水电站群规模庞大。此外,这些电站除了发电以外,还具有防洪、供水、灌溉、航运、生态环境保护等功能目标。如此复杂巨系统的多目标优化调度,国内外还没有成功范例,相关调度理论和优化方法,迫切需要解决。
The joint operation of large-scale hydropower stations in the upper reaches of the Yangtze River is a complex giant system involving many fields, such as natural sciences, engineering technology, economic policies and management laws and regulations. To achieve cascade hydropower station multi-objective, multi-task, multi-scale joint scheduling, requires strong technical support. First, the basic scientific issues yet to be studied 1, the multi-objective joint operation of cascade hydropower station complex giant system optimization theory. According to the plan, in 2030, more than 80 large-scale hydropower stations will be built in the upper reaches of the Yangtze River, with a large-scale dry-tributary cascade hydropower station. In addition, in addition to power generation, these power stations also have such functional targets as flood control, water supply, irrigation, shipping and ecological environment protection. Multi-objective optimization scheduling of such a complex giant system has not been successful at home and abroad, the relevant scheduling theory and optimization methods, which urgently need to be solved.
