“…O artigo [13] apresenta uma proposta de PLL trifásico no referencial síncrono que emprega SOGI modificado em conjunto com a técnica MAF com o objetivo de melhorar a rejeição das componentes contínuas do sinal. O artigo [14] apresenta uma proposta de PLL monofásico no referencial síncrono que emprega SOGI em conjunto com MAF num PLL no referencial dq numa aplicação de detecção de ilhamento e não apresenta teste com tensão distorcida ou afundamento. O artigo [15] apresenta uma proposta de PLL trifásico no referencial síncrono com SOGI modificado e com a inserção do MAF em conjunto com filtro passa-baixa no PLL no referencial dq.…”

This article proposes a linear filtering procedure to improve the performance of a PLL algorithm, based on the structure of a generalized second order integrator (SOGI), using a one-cycle Fourier filter (OCF) to filter stationary voltages αβ generated directly by a SOGI structure. In addition, a comparison is made between conventional SOGI and also with a moving average filter (MAF), with this filter applied to the synchronous dq voltages produced by the αβ to dq transformation at the output of the SOGI structure. The comparisons are made with signals affected by different harmonic distortions and with sinking voltages similar to those obtained in power networks under fault conditions. The results of the comparisons show that the two approaches, OCF and MAF, improve the dynamics

“…Generally, the distribution grid has abnormal working conditions. Various controls, for instance frequency locked loop (FLL) [13], second-order generalised integrator (SOGI) [14], Prony's method (PM), discreet Fourier transform (DFT) and Kalman filter (KF) [15] approaches, are given in the literature for abnormal grid working conditions. The SOGI and FLL based controls are incapable to take care of low-order harmonics and DC offset.…”

The contribution of power because of the nonconventional energy sources is enhancing day by day. This gives rise to power converter connected to the grid for an integration and to utilize the nonconventional energy sources economically and efficiently. However, this causes the distortion in the grid voltages and currents. All advanced high precision operating machines and measuring instruments are sensitive to the harmonics of the grid voltages. Therefore, this work illustrates an improved control to supress the grid voltage and current harmonics caused by an integration of non-conventional energy source and nonlinear loads. An enhanced resonant two-degree of freedom proportional-integral-derivative (ER-2-DOF-PID) controller is used to extract fundamental components from load currents. It uses a resonant controller in shunt with PI controller to suppress the multi-order harmonics and steady state error. A DC-offset is used in parallel of this combination to suppress the sub-order harmonics. To suppress the peak overshoot during the load transients and insolation changes, a 2-DOF-PID controller is used. The presented control is investigated by developing its model in MATLAB environment and this is validated on a prototype developed in the laboratory. The controller is modelled and investigated for stability analysis using a Bode mathematical tool..
