摘　　要：针对A、B两大梯级电站弃水以及调峰压力问题,以提高两流域梯级整体发电量为目标,提出年发电用水量补偿机制,通过长距离水库抽水蓄能跨流域引水方式平衡两梯级用水量、发电量,减少弃水量,采用逐步优化算法(POA)与水位廊道耦合对跨流域梯级水电站中长期优化调度模型进行求解.算例仿真验证结果表明,所提模型与方法能提高梯级B整体发电量,减少梯级A弃水,对于A、B两流域引水优化调度有一定的指导意义.Aiming at the problems of waste water and peak-shaving pressure in A and B cascade hydropower stations,with the goal of improving the overall cascade power generation capacity of the two basins,a compensation mechanism for annual power generation water consumption is proposed,which balances the two cascade water consumption and power generation through long-distance reservoir pumping and storage,and reduces the discarded water consumption through cross-basin diversion.In this paper,a step-by-step optimization algorithm(POA)coupled with water level corridor method is used to solve the medium and long term optimal dispatching model of cascade hydropower stations across river basins.The simulation results show that the proposed model and method can improve the overall power generation capacity of cascade B,reduce cascade A wastewater.It has certain research significance for the optimal dispatch of water diversion in A and B basins.
