摘要 以系统运行的经济性和可靠性为目标,提出了一种抽水蓄能电站的综合规划模型。该模型不仅考虑了系统需求约束、备用约束以及电站静态运行约束,而且考虑了能源约束、环保约束以及各类型电站的爬坡和旋转备用容量等动态运行约束。通过对规划方案进行静态运行模拟和动态特性模拟,得到抽水蓄能电站的动静态效益指标;基于综合效益比较,从拟定的方案中找出系统对抽水蓄能电站的最佳需求空间和装机进度。应用该方法对某省级系统进行了算例计算分析,结果表明了所述模型的有效性。 Aimed at the least annual accounting fee and the highest reliability, a novel mathematical model for optimal expansion planning of the pumped-storage station is presented. The constraints of the model consist of two types, the Conventional type involving system demand and reserve capability constraints, operation characteristic of the generation unit constraints, energy sources consumption of generation station constraints, reservoir capability and spare capability of pumped storage station constraints, etc. The other type includes pollution emission constraints, ramp rate of generation unit constraints, dynamic reserve capability constraints, etc. By Simulating the production dispatch and dynamic process in the case of system fault and load variation, the static benefit and dynamic benefit can be obtained. The most desirable planning scheme of pumped-storage stations can be found from all possible schemes by comparing all indices. The case study of an actual provincial power system shows the practicability and feasibility of the method.
