    "body_text": "Large computing loads can create oscillations even as operators expect them to help the grid. This work derives conditions for distinguishing disturbance sources and a limit on simultaneous isolation and support. A local storage controller outperformed equal-order comparators in two simulated networks while meeting the required grid response. The evidence is a control study, not an operating data-center deployment.",
