摘　　要：针对高比例光伏发电渗透下水光互补系统源-荷同步性显著下降的问题,构建了一种外层长期水量调蓄与内层短期电力互补相耦合的嵌套调度模型。该模型在外层识别光伏出力与负荷曲线特征,而在内层基于源-荷匹配机制,根据水、光、荷特性将输电通道划分为多个目标空间,并采用层内目标分级与层间全局搜索的耦合联动机制,求解输电通道电量配比,得到各目标空间的电量分布情况。澜沧江西藏段水光互补系统实例分析结果表明,构建的模型能够有效引导系统运行工况趋近目标偏好区域,所制订的调度方案能够满足短期弃电、波动风险控制与电力调峰需求,验证了模型的合理性。Aiming at the problem of the significant decline in source-load synchronization of a hydro-photovoltaic complementary system under the penetration of a high percentage of photovoltaic power generation,a nested scheduling model that couples long-term water storage regulation in the outer layer with short-term power complementary in the inner layer is constructed.The model identifies the characteristics of photovoltaic output and load curve in the outer layer,while in the inner layer,based on the source-load matching mechanism,it divides the transmission channel into multiple target spaces according to the characteristics of water,light and load.The model employs the coupling linkage mechanism of intra-layer target classification and inter-layer global search to solve the power allocation of the transmission channel and obtain the power distribution in each target space.The results of the case study of the hydro-photovoltaic complementary system in the Xizang section of the Lancang River show that the constructed model can effectively guide the operating conditions of the system to approach the target preference region,and the formulated scheduling scheme can meet the requirements of short-term power curtailment,fluctuation risk control and power peak regulation,verifying the rationality of the model.
