4月28日,欧洲伊比利亚半岛发生大规模停电事故。在全球能源转型持续深入推进的背景下,该事件究 竟是偶然现象,还是带有某种阶段性的必然? 现代电网具有天然的脆弱性 作为现代社会最重要的能源基础设施之一,电网的安全稳定运行关乎国计民生,实为"国之大者"。但现 代电网已经发展为由物理电力和信息通信构成的复杂耦合网络系统,具有与生俱来的脆弱性。 现代电网已经成为有史以来规模最大的人造网络系统,而电网具有超大规模网络内生的级联故障风险。 以我国为例,到2023年底,我国仅220千伏及以上的输电线路就已超过92万千米,电网运营线路总里程 超过350万千米,形成多达数百万节点的复杂拓扑结构。稍有不慎,高度互联特性就会使得局部故障扩 散、放大至区域甚至跨区电网,造成不可估量的损失。 电网受实时平衡的物理约束,对电压、频率的扰动极为敏感。为保障电力供应,电力系统需遵循严格的 能量守恒定律,发电与用电必须实现毫秒级动态平衡。国内外案例显示,电压偏差超过±10%或频率偏 差超过±0.5赫兹,都可能导致设备故障或系统不稳定,严重者甚至可能导致部分电网解列或大面积停 电。 电网设备绝大多数直接暴露于自然环境中,对环境变化的敏感性极高, ...
