中国的风能和太阳能等可再生能源资源非常丰富。大规模具有波动性的电源接入电网将会给电网的安全稳定运行带来挑战。但是合理利用广域范围内风能和太阳能等资源的时空互补性可以有效降低其输出功率波动。基于中国气象局提供的大量气象站点实测小时级别风速和太阳辐射强度数据，分析和研究了不同组合场景下广域范围内的风电和太阳能资源之间的时空互补性。研究表明在不同时间尺度下(月，中国的风能和太阳能等可再生能源资源非常丰富。大规模具有波动性的电源接入电网将会给电网的安全稳定运行带来挑战。但是合理利用广域范围内风能和太阳能等资源的时空互补性可以有效降低其输出功率波动。基于中国气象局提供的大量气象站点实测小时级别风速和太阳辐射强度数据，分析和研究了不同组合场景下广域范围内的风电和太阳能资源之间的时空互补性。研究表明在不同时间尺度下(月，日，小时)中国大陆北部和东部沿海广域范围内风能和太阳能资源具有良好时空互补性，其中日时间尺度下互补性最强。同时，在各时间尺度下这两种可再生能源装机容量存在着使其时空互补性最强的组合比例。再者，分散区域越大，风电所占比重越大的组合场景小时时间尺度的时空互补性越强。

China is abundant in wind and solar energy resources, such large amounts of variable power sources are likely to be included in China’s future power systems and will bring significant challenges in safe and stable operation. Making use of the temporospatial complementarities between the two power sources is a quite feasible way to reduce the fluctuant and intermittent output. Based on the hourly climatic data which are provided by China meteorological administration (CMA), this paper presented the complementarities between solar and wind power under different combining scenarios. The results show that solar and wind power have enormous smoothing effect on various time scales, from hourly to monthly, but the complementary effect is strongest in daily totals. An optimal combining scenario exists to get the best complementary effect. Furthermore, hourly complementary effect for the scenarios with a larger share of wind power tends to be stronger.
