A phase-locked loop (PLL) based on synchronous reference frame (SRF) is a standard PLL that has a simple construction and performs well under undisrupted grid conditions. However, in imbalanced and harmonically disturbed environments, the fundamental grid voltage characteristics deteriorate greatly. Integrating a variety of filters in the control algorithm has been suggested as a solution to address this issue. An optimal low-pass filter characteristic can be achieved with the Savitzky-Golay filter (SGF), which is a zero-phase smoothing filter. The primary objective of this article is to offer a new small-signal design of SGF-based filtration in the SRF-PLL. Using this model, a researcher can easily evaluate the SGF-PLL's behavior and stability condition. A comparative analysis on performance evaluation is carried out with other PLLs, and the findings represent the principal achievements of this article. This includes a substantial improvement in dynamic response and harmonic prof ....
