随着清洁能源一体化基地建设投产，多能源联合调度需求迫切。在梯级水电联合调度的基础上，嵌入通道弃电风险作为惩罚约束，将调度人员工作经验与滚动思想相融合，提出一种基于实际运行的多时间尺度梯级水光互补联合调度规则制定方法，提前识别可能存在的弃电风险并提出控制措施，选用水电发电与蓄能效益、光伏发电效益构建水光联合系统互补函数对调度规则进行评价，最后将所提方法应用于澜沧江小湾—漫湾水光互补系统中。结果表明，在不显著影响水电调节作用的同时实现了水光联合系统经济效益显著增加，具备推广至未来流域水风光储清洁能源一体化基地联合运行的可行性。

With the construction and operation of integrated clean energy bases, there is an urgent need for multi-energy joint dispatch. On the basis of cascade hydropower joint scheduling, this article embeds the risk of channel electricity curtailment as a penalty constraint, integrates the working experience of scheduling personnels with rolling ideas, and explores a method for formulating multi-time scale cascade hydro-photovoltaic complementary joint scheduling rules based on actual operation. The potential risks of power abandonment is identified in advance and control measures are proposed. By selecting the benefits of hydroelectric power generation and energy storage, as well as photovoltaic power generation, a complementary function of hydro-photovoltaic joint system is established to evaluate the scheduling rules. The proposed method has been applied to the hydro-photovoltaic complementary system of Xiaowan and Manwan on the Lancang River. The results show that the economic benefits of the hydro-photovoltaic joint system is significantly increased without significantly affecting the hydropower regulations. The idea has the feasibility of promoting the joint operation of the integrated hydro-photovoltaic energy storage and clean energy watershed base in future.
