摘　　要：在光伏发电装机大规模发展的情况下,为研究日食对电网安全的影响,分析了2015年3月20日德国日全食基本情况,并基于运行数据分析了德国电网应对日全食的举措。研究结果表明,准确的新能源出力预测是防范电网安全运行风险的重要前提,充足的可调度资源是保证大比例新能源并网条件下系统安全运行的基础,合理的电力市场设计是降低大比例新能源对系统安全风险的重要手段。This paper analyzes the safly operation conditions during the solar eclipse happened in Germany on March 20th 2015. Based on the operational data, an analysis is made on the measures taken by the German power system operators to deal with the impact of solar eclipse on power system operation. The results show that accurate solar generation forecast is an important precondition for preventing power grid from operational risks brought about by variable generations. Besides, plentiful dispatchable generation resources such as coal fired generation, power grid interconnection are the basis for assuring system opeartion security with high penetrations of variable generations. Good electricity market design is also an important way to reduce the risks brought about by variable generations.
