这个参考文献列表涵盖了向高比例可再生能源、低惯性运行的电力系统过渡及其运行挑战的研究。关键主题包括100%可再生能源电力可行性、电网控制中心、可再生能源市场整合、电动汽车、热泵和人工智能数据中心对需求侧的影响,以及电网基础设施的就绪程度。还涵盖重大停电原因、信息物理漏洞和虚假数据注入攻击,以及网络弹性需求。频率稳定性是核心关注点,涉及低惯性动力学、一次频率响应、超低频和区域间振荡、确定性偏差、市场影响以及涡轮磨损等方面的工作。其他主题包括电池储能展望、欧洲网络发展、数据中心电力特性、微灵活性,以及电网频率的测量与监测方法。总体而言,所引用的文献强调,实现可靠、碳中和的电力需要在规划、控制、市场设计、灵活性和网络安全方面进行协调升级。

《自然能源》的一篇文章讨论了由同步数字设备引起的一分钟电力系统频率扰动。UPS电池系统及其他设备在精确的分钟边界运行周期性自检或计划任务;当许多设备共享NTP同步时钟时,它们的组合负载会产生重复尖峰。评论者将其与惊群效应和注入锁定问题相比,提出随机启动延迟、互质定时器间隔、错峰cron作业和软启动/浪涌管理等缓解措施。一些人指出硬件自检和浪涌电流可能使断路器过载,其他人讨论了该效应是否足够显著以及潜在的电网控制担忧。总体而言,该讨论强调许多设备间微小的协调定时行为可聚合为可测量的电网频率效应,而简单的随机化可减少同步。
