    "body_text": "The study adds simplified inertia and voltage-stability constraints directly to expansion planning instead of selecting stabilizing measures afterward. In the tested power-system scenarios, the integrated formulation reduced modeled system costs and favored grid-forming battery storage over single-purpose measures such as static synchronous compensators because batteries could serve both energy and stability needs. These are model results under the paper's assumptions, not a forecast for a named grid or a procurement recommendation.",
