Abstract: Frequent sub-synchronous oscillation (SSO) incidents have revealed the incompatibility between wind power grid-connection technical standards and the new power system's requirements. This paper analyzes the core evolution of the GB/T 19963 standard system's 2011 version, 2021 onshore version, and 2024 offshore version of wind farm grid-connection technical standards. Focusing on key areas such as dynamic response, fault ride-through, and reactive power-voltage control, it explores how standard upgrades enhance wind farms'ability to support grid stability. The new standards, with requirements like inertia response, primary frequency regulation, and continuous high/low-voltage ride-through, have strengthened wind farms' active support functions. Offshore wind power standards offer differentiated technical specifications for special scenarios like VSC-HVDC transmission and wide-frequency oscillation. These standards not only provide scientific basis for wind farm planning, design, and grid connection but also show the new energy standard system's evolution from “scale” to“refinement”, offering references for new power system standard construction.
