John Kemp: 我在停电发生前从未想过西班牙的电网问题。这次事件表明,西班牙和葡萄牙的电网比我们想象的更加脆弱,因为它们需要持续匹配发电和电力消耗。尽管电网本身就脆弱,但像这样大范围的停电事件在发达国家非常罕见。这次事件的关键问题在于,为什么多层保护机制全部失效了,一个小故障却导致整个系统瘫痪。旋转惯性在电网稳定性中起着关键作用,传统发电机可以提供这种惯性,而太阳能和风能发电则不能。随着可再生能源在电网中的占比增加,电网固有的惯性会降低,这可能会造成问题,但我们不应该陷入关于传统发电和可再生能源孰优孰劣的道德讨论。西班牙的停电事件可能并非警示,而是将原本电力工程师和监管机构之间的技术讨论提升到了政策层面。为了应对可再生能源占比增加带来的挑战,我们可以使用同步调相机等技术来提高电网稳定性。西班牙停电事件很可能源于西南部的太阳能发电厂故障,而电网的恢复能力不足以应对后续的故障。这次事件突显了在可再生能源占比很高的情况下管理电网的一些关键问题,并可能促使相关技术的应用。 Felix Salmon: 西班牙和葡萄牙的这次大停电事件影响巨大,医院手术室和电梯都停电了。我们需要弄清楚究竟发生了什么,以及这是否是由于过多的太阳能电力造成的。 Emily Peck: 这次事件提醒我们,GDP并非衡量经济的唯一标准,它忽略了许多重要的因素,例如医疗保健、生活质量和无偿劳动。 Elizabeth Spiers: 这次事件也引发了人们对公司绩效评估方法的反思,例如‘末位淘汰制’等方法可能会损害员工士气并阻碍团队合作。

Shownotes Transcript

This week: The entire Iberian peninsula lost power for 18 hours. Felix Salmon), Emily Peck), and Elizabeth Spiers) are joined by energy expert John Kemp to talk about why that might have happened and nerd out on power grids. Then, the GDP is down by 0.3%. But is that really the right metric to care about? Finally, the tech world is bringing back the brutal system of stack ranking management. The hosts discuss why this might be ill advised.
