摘　　要：光伏发电具有昼发夜停的特点,日内出力过程呈“钟型”;风力发电出力随机性强,并呈现反调峰特点。通过水电调节平抑风电和光伏发电的随机波动,水风光互补利用是支撑“双碳”目标实现的有效途径。在此背景下,针对现有水风光电源并网接入场景,分析了我国典型水风光清洁能源互补开发形式,探析了大规模水风光电源依托电网互补和打捆互补调度模式,对比分析了两种调度模式的优缺点,并对大规模水风光互补调度关键技术进行展望,为将来大规模水风光互补利用提供参考。Photovoltaic power generation has the characteristic of generating electricity during the daytime,resulting in a bell-shaped daily output process.Wind power generation has strong randomness in output and exhibits anti-peak regulation characteristics.The regulation of hydropower to suppress the random fluctuations of wind and photovoltaic power generation is an effective way to comprehensively utilize renewable energy and achieve the dual carbon goal.In this context,based on the existing scenarios of grid-connection of hydropower,wind,and photovoltaic power,this paper analyzes the typical complementary development forms of hydropower-wind-photovoltaic clean energy in China.Then,two complementary scheduling modes consisting of relying on the power grid and bundling integration are analyzed,and advantages and disadvantages of the two scheduling modes are compared.Also,prospect of key technologies for large-scale complementary scheduling of are analyzed.This study will provide references for future large-scale hydropower-wind-photovoltaic complementary utilization.
