【摘要】 针对一个含有抽水蓄能水库的梯级水库群水电站短期优化调度问题,建立了一个能综合考虑非线性水电转换关系、蓄能电站机组特性、最小开关机时间、水库间水力耦合、库容及河道容量约束等众多因素的调度模型,通过引入适当的整数变量将其转换为线性混合整数规划问题,在此基础上采用CPLEX优化软件包求解,对一个包含3个梯级水库12台机组及一个抽水蓄能水库5台抽蓄机组的模拟系统进行了测试,初步结果表明文中所采用的线性化方法非常有效和实用,能灵活处理含有抽水蓄能水库的水库群水电站短期调度中的多种复杂因素。更多还原

【Abstract】 In this paper,the short-term scheduling of cascaded hydroelectric chain plants with pumped-storage units is con-sidered.Some integer variables are carefully introduced such that the original problem is successfully formulated as a mixed-integer linear programming.The model given in this paper admits of many complex characteristics such as nonlinear hydroelectric production function,minimum/maximum down/up time of hydro units,existence of pumped-units and time delay between plants,etc.CPLEX package is adopted to solve the problem.Numerical testing is also performed for a system with 3 cascaded reservoir,12 hydro units and a pumped-storage plant with 5 pumped-units.The results suggest that the mixed-integer programming model given in this paper is very effective.更多还原
