摘　　要：针对梯级多主体水电站联合调度时传统效益分摊方法计算量大,以及水电面临市场化深度影响的问题,提出市场经济下梯级水电站群联合调度效益分摊方法。首先采用“还原法”计算联合调度时入库流量,以改进发电量-电价函数拟合市场电价对市场经济下梯级水电站群发电效益最大模型进行求解;然后以信息熵法将市场经济下梯级电站间复杂效益联系量化为各电站效益贡献所代表的效益分摊比例,以竞争力指数法将电站特征参数转化为电站竞争力所代表的效益分摊比例,采用线性加权法将两者结合对梯级联合调度效益进行分摊;最后采用满意度评价与分配策略倾向分析对分摊结果进行双重评定。乌江梯级实例结果如下:3座电站与6座电站联合调度效益分摊时本文方法与以Shapley值法为基础的客观权重组合分摊方法、损失比例法等分摊方法相比:分摊结果分配策略倾向分析最大值更小且方差平均值更低,各主体满意度方差最小,说明效益分摊结果公平性和合理性更好;三座电站与六座电站效益分摊分别仅需四条、七条效益信息,说明计算效率更高。分摊结果表明本研究方法能够以较少的效益信息量有效解决多主体梯级水电站联合调度效益分摊问题,对实现市场背景下的多主体梯级水电联合优化调度具有一定参考意义。In view of the large amount of calculation of the traditional benefit allocation method in the joint operation of cascade multi-agent hydropower stations,and the influence of the depth of marketization on hydropower,a benefit allocation method for joint operation of cascade hydropower stations under market economy is put forward.Firstly,the inflow into the reservoir during joint dispatching is calculated by using the“reduction method”,and the maximum power generation benefit model of cascade hydropower stations under the market economy is solved by improving the electricity generation-electricity price function to fit the market electricity price.Then the information entropy method is used to quantify the complex benefit relationship between cascade power stations under the market economy as the benefit sharing ratio represented by the benefit contribution of each power station,and the competitiveness index method is used to transform the power station characteristic parameters into the benefit sharing ratio represented by the power station competitiveness.The linear weighting method is used to share the benefits of cascade joint dispatching.Finally,the evaluation of satisfaction and the tendency analysis of allocation strategy are used to evaluate the allocation results.The results of Wujiang cascade examples are as follows:compared with objective weight combination allocation method and loss proportion method based on Shapley Value Method,this method is compared with objective weight combination allocation method and loss proportion method for benefit allocation of three power stations and six power stations.The maximum value and the average variance of the allocation strategy tend to be smaller,and the variance of the satisfaction of each subject is the smallest,which shows that the result of benefit allocation is more fair and reasonable.The benefit sharing of three power stations and six power stations requires only four and seven pieces of benefit information respectively,indicating that the calculation
