Abstract: Impedance analysis plays an important role in the research on subsynchronous oscillation stability of wind power grid integration. Focusing on the impedance modeling, stability criteria and measurement technology of grid-connected inverters, this paper introduces three modeling methods for wind power grid integration systems based on impedance analysis, and presents their mutual conversion relationships and application characteristics; summarizes the stability criteria based on impedance analysis; and concludes the key technologies of impedance measurement, including offline and online measurement schemes as well as their implementation features. On this basis, the limitations of existing research are pointed out. In the future, through refined modeling, multi-criterion fusion and advanced measurement technology, a full-scenario stability analysis system for wind power grid integration systems should be constructed to provide support for the safety and stability of power systems with a high proportion of new energy.
Key words: wind power grid integration system; subsynchronous oscillation; impedance analysis method; impedance modeling; stability criteria; impedance measurement
