摘要: 以雅砻江梯级电站发电量最大为目标，综合考虑各约束条件，建立梯级水库发电调度模型，采用逐次渐近动态规划–逐次优化混合算法(DPSA-POA)进行求解。研究结果表明：联合优化调度与常规调度方案对比，两河口、锦屏一级、二滩电站的年均发电量分别提高了4.5亿kW•h (4.14%)、20.14亿kW•h (10.67%)和19.39亿kW•h (11.46%)；雅砻江梯级水库的年弃水量减少了65.91亿m3，联合优化调度的经济效益巨大。
Abstract: The joint operation model of cascade reservoirs in the Yalong River is established with objective func-tions to maximize power generation, and solved by mixed DPSA-POA algorithm with constraints. Com-pared with the conventional operation scheme, the mid-long term joint optimal operation of cascade reservoirs can increase annual hydropower power generation in Lianghekou, Jinping-I, Ertan by 0.450 (or 4.14%), 2.014 (or 10.67%), 1.939 billion kW•h (or 11.46%), respectively. Meanwhile, it can reduce 6.591 billion m3 (or 57.49%) spillway discharge annually. Application results show that optimal cascade operation can enhance power generation substantially, as well as advancing economic benefit for Yalong River.
