Abstract：Renewable energy generation represented by wind and solar power has significant volatility and uncertainty, making the development of active support wind turbines and enhancement of the active support capability of renewable energy generation crucial approaches for constructing new power systems. Research reveals that traditional doubly-fed induction generators cannot effectively support voltage and frequency during transient changes in grid voltage and frequency, which is detrimental to the stable operation of the power system. To address these issues, this study first establishes a mathematical model of doubly-fed induction generator based on supercapacitors, incorporates supercapacitor energy storage and active support control strategies into traditional doubly- fed induction generators, and verifies through simulation that this method can effectively enhance the active support capability of doubly-fed induction generators.
