GPU workloads can sabotage power grids from the cloud, researchers warn
A new study shows a cloud tenant can modulate GPU power draw at >6 kHz, and coordinating 1,000 GPUs in a 1 MW DER‑rich site spikes current THD to 46.8% and drives the damping ratio negative, threatening grid stability. The paper urges cross‑layer defenses linking workload scheduling to power‑electronics monitoring.
