2015年3月20日日食对德国电网的影响
发布时间:2018-07-17 03:13
【摘要】:由于德国的可再生能源发电占比很高,2015年3月20日发生的日偏食使德国光伏出力在短时间内大幅度波动,对德国的电力平衡、电网安全造成了威胁,也影响了电力交易。但最终德国没有发生任何电力短缺或停电,并且电网频率波动甚至比平常还要小。通过分析日食当日与非日食日的电力数据,以及电网公司采取的措施,探讨了光伏大规模接入电网后遇到极端自然现象时的经验与预防措施。结果表明,电网的合理规划设计、适当的虚拟电厂以及需求侧管理技术和调度部门的协作对于维持供电安全有着重要意义。
[Abstract]:Due to the high proportion of renewable energy generation in Germany, the partial solar eclipse on March 20, 2015 made the German photovoltaic force fluctuate greatly in a short time, which threatened the German power balance and power grid security, and also affected the electricity trade. In the end, however, there were no power shortages or power cuts in Germany, and the frequency of the grid fluctuated even less than usual. Based on the analysis of power data of solar eclipse and non-solar eclipse and the measures taken by grid companies, the experience and preventive measures of extreme natural phenomena after large-scale photovoltaic connection to power grid are discussed. The results show that the reasonable planning and design of the power network, the proper virtual power plant, the cooperation of the demand-side management technology and the dispatching department are of great significance for the maintenance of power supply security.
