摘　　要：目前多能互补规模研究多集中于小型系统,鲜有针对千万千瓦级别多能互补规模的研究。为此,提出了一种适用于金沙江下游千万千瓦级多能互补系统水风光资源互补规模的计算方法。首先按照“宜送则送、宜留则留”的原则来确定外送和留存规模;然后根据四川、云南两省的新能源资源和规划装机分布情况,选择适合建设可再生能源多能互补基地的大型水电站;再以受端电网消纳、接入电网安全为前提并结合水电站配套直流通道利用情况以及直流受端省份可消纳空间,以新能源装机规模最大、新能源及水电弃电量最小为目标,考虑电力电量平衡约束以及水电站发电约束,提出了新增外送新能源规模计算模型。以金沙江下游溪洛渡、白鹤滩和乌东德水电站为研究实例,计算出2023~2025年可新增外送新能源规模。最终推荐溪洛渡水电站接入新能源总规模约354万kW,其中风电装机容量86万kW,光伏装机容量268万kW;白鹤滩水电站接入新能源总规模约449万kW,其中风电装机容量141万kW,光伏装机容量308万kW;乌东德水电站右岸接入新能源总规模约245.7万kW,其中风电装机容量110.7万kW,光伏装机容量135万kW。At present, the research on the scale of multi-energy complementarity mostly focuses on small-scale systems, and there is little research on the scale at the level of 10 million kilowatts.In view of the above situation, this paper puts forward a calculation method of the complementary scale of hydro-wind-solar, which is suitable for the ten million kilowatt level multi energy complementary system in the lower reaches of the Jinsha River.First, this paper determines the scale of delivery and retention according to the principle of “sending when appropriate and retaining when appropriate”,and then selects large-scale hydropower stations suitable for building renewable energy multi-energy complementary bases according to the new energy resources and planned installation capacity distribution in Sichuan and Yunnan provinces.On the premise of receiving end consumption and grid access safety, combined with the utilization of the supporting DC channels of hydropower stations and the available consumption space of DC receiving end provinces, the calculation model for the scale of new energy to be sent out is proposed, aiming at the maximum installation scale of new energy and the minimum abandoned power of new energy and hydropower, and considering the constraints of power balance and hydropower generation.Taking Xiluodu, Baihetan and Wudongde Hydropower Stations in the lower reaches of Jinsha River as research examples, the scale of new energy that can be newly delivered from 2023 to 2025 is calculated.Finally, it is recommended that Xiluodu hydropower station be connected to new energy with a total scale of about 3.54 million kilowatt, including 860 thousand kilowatt of wind power installation capacity and 2.68 million kilowatt of photovoltaic installation capacity;The total scale of Baihetan Hydropower station connected to new energy is about 4.49 million kilowatt, of which the installation capacity of wind power is 1.41 million kilowatt and the installation capacity of photovoltaic is 3.08 million kilowatt;The to
