Abstract:

With large-scale penetration of wind power into power systems, the dynamic interaction between wind power generators and synchronous generators is intensified. The negative impact and positive control effect of wind power generators on the low-frequency oscillation (LFO) in power systems is increasingly obvious. This paper investigates the LFO damping in power systems with doubly-fed induction generators (DFIGs). The mechanism of DFIG influencing the LFO is described. The damping measures from the wind farm or power system are compared. LFO damping strategies with parameter tuning and control strategy design to the DFIG power oscillation damper (POD) are discussed. The parameter tuning based on traditional methods, optimization, robust design, etc., are compared. And the control design methods such as linear quadratic regulator (LQR), active disturbance rejection control (ADRC), sliding mode control (SMC), fuzzy control are also compared. Suggestions to the future research on the LFO damping in DFIG integrated power systems are given.

Key words: doubly-fed induction generator (DFIG), integrated power system, low frequency oscillation (LFO), power oscillation damper (POD), parameter tuning, control strategy
