“…The undesired oscillations caused by abnormal and faulty grid conditions can be mitigated using adaptive or notch filters in the PLL algorithm [63][64][65][66][67]. Based on the Schur lattice structure in [64], adaptive notch filters with infinite impulse responses are implemented to improve the performance of the conventional SRF under variable frequency and unbalanced grid voltage conditions.…”

“…This scheme provides robustness against voltage unbalance. In [28], a notch filter is implemented inside the loop to improve the filtering characteristics. An adaptive low-pass notch filter-based PLL is presented in [19].…”

“…However, in Phipps et al (2006), a novel PLL design was proposed which, unlike traditional three-phase PLL, required no coordinate transformation. An optimized digital implementation of PLLs is presented in Freijedo et al (2011), where the digital oscillator is used to execute trigonometric functions. Jain et al (2014) focuses on optimizing the dynamic response of the PLL for fast tracking under disturbance.…”
