摘要
2016年至今发生的南澳、英国、美国得州、巴西、智利、西班牙、葡萄牙等大停电事故均具有新能源高占比特征,对于做好转型期我国电网安全和电力保供工作具有重要警示和借鉴意义。该文首先介绍近年国外高比例新能源电力系统发生的大停电事故情况;然后,围绕网架结构、电源支撑、安全防线、网源协调、运行管控机制等方面,总结梳理高比例新能源电力系统大停电暴露出的共性问题;最后,结合我国能源转型和构建新型电力系统的新形势,提出保障大电网安全运行和防范大面积停电的相关措施和建议。
Since 2016,several power blackout events have occurred in power systems with high proportion of renewable energy,notably in South Australia,the UK,Texas(USA),Brazil,Chile,Spain and Portugal,which provide important warnings and lessons for ensuring China’s power system security and power supply reliability.In this paper,these power blackout events are introduced.Secondly,the common causes of the blackout are analyzed from aspects including power grid structure,power source support,system security defense,coordination between the grid and generation sources,and operation management mechanisms.Finally,combined with the recent development in the energy transition and the new power system construction in China,the relevant measures and recommendations are proposed in order to guarantee secure operation of the large interconnected power system and prevent large-scale blackout.
