Construction of detailed energy function of double‐fed induction generator for small signal stability analysis of power systems with a high penetration of double‐fed induction generator

The integration of high proportion renewable energy not only brings many benefits, but also increases the difficulty power system stability analysis. One reasons for this problem is unclear internal characteristics new equipment. Therefore, there an urgent need a more detailed analysis Taking double-fed induction generator (DFIG), which has complex operation and widely used, as example, function (DEF) DFIG small signal proposed in paper. This method performs DFIG's analysis, making traditional structure comprehensive. On basis, parameters with sensitivity to are obtained, damping evaluation index constructed evaluate DFIG. Finally, model's correctness verified 4-generator 2-area system.
