“…at 50 Hz with a total harmonic distortion (THD) of 10.67% while the harmonics, i.e., h = 3, 5, 7, 9, 11, 13, 15, 17 are considered as per EN 50160 standard [16]. The proposed scheme is compared with the single-phase configuration of CSTF-PLL [13] and ESTF-PLL [14] techniques along with a demodulation based PLL [4]. The control parameters for DT-PLL are α = 400, β = 50 and γ = 50.…”

“…Hence, an improved STF can be developed as compared to the single-phase version of the CSTF applied for an active power filter (APF) application, reported in [13]. Further, the harmonic and the DC-offset free FOCs obtained in the output of proposed STF are denoted as follows:…”

“…However, high sampling frequency may offer better accuracy in the estimation [12], but at the expense of an increase in hardware cost and memory storage. In this study, an enhanced version of well-known self-tuning filter [13] is designed optimally to provide better immunity towards DCoffset and harmonics. Importantly, the proposed enhanced SFT is computationally simpler to implement as compared to recently proposed extended STF [14].…”

“…In the Ngo et al, 15 for source current reference generation, SRF theory is utilized along with DFCE, and due to that, computation requirement is high. Moreover, in Bhat et al, 16 DFCE is utilized along with the instantaneous power method. In other works, 1,17 STF (self tuning filter)‐based DFCE is utilized to extract unit template for appropriate reference current generation.…”

Summary Synchronizing methodology for shunt active power filter (SAPF) based on the resonant controller using generalized integrator (GI) in the stationary reference frame is of great interest for researchers now a day. In this paper, a phase synchronizing technique based on the complex coefficient filter (CCF) embedded with a frequency locked loop (FLL) is proposed for the fundamental active and reactive component extraction of load current and unit template generation from grid supply. The proposed CCF‐FLL–based control works effectively under varying grid frequency, distorted and unbalance grid voltage conditions to generate the reference source current at a unity power factor for proper harmonic compensation using an indirect current control method. In this work, a detailed mathematical modeling for development of control logic for CCF‐FLL is done, and its feasibility with the bode plot is also confirmed. Simulation for SAPF is performed using both CCF and CCF‐FLL–based control strategy separately to judge the performance of each. Simulation confirms that the proposed CCF‐FLL based control is capable of maintaining the source current with low total harmonic distortion (THD) as per the IEEE‐519 standard with the nonlinear load. The effectiveness of the proposed controller for desired harmonics compensation is also validated through real‐time simulation using OPAL‐RT OP4510 platform.
