“…A series hybrid active power filter based on controllable harmonic impedance to minimize inverter capacity and improve system reliability, is deliberated [15]. The compensation of current harmonics arising because of high-power rectifiers is presented and analyzed [16]. A mathematical representation of the Series Hybrid Active Power Filter is established in [17] to improve the filtering capacity.…”

A compensation method for mitigation of voltage related power quality problems with the use of Series Voltage Regulator well known as Series Active Power Filter or Dynamic Voltage Restorer is presented in this paper. The classical control algorithm used for series voltage regulator based on the Park transformation is modified by introducing a Selective Harmonic Filter at detection stage of source current in order to compensate harmonic frequencies which mainly affect power frequency voltages. The significant outcomes are sag restoration, reduction of total harmonic distortion and removal of transients from the supply voltage. Thus it makes possible to improve performance of series voltage controller as power conditioner to mitigate various voltage related power quality issues. The proposed approach is cost effective because same series voltage controller can be used as power conditioner by modifying control strategy used. Also it is possible to eliminate use of PI controller from control circuitry. The usefulness and robustness of the proposed mitigation strategy is confirmed by simulation studies. The presented series voltage controller has ability to mitigate the power quality issues arising due to charging of electric vehicles.

“…Due to the limitations in passive devices, active devices have caught attention over these years. Acuna et al 2 used a series active filter to compensate current harmonics injected by high-power rectifiers. Wu et al 3 presented an APF with division-summation digital control to shape source current by introducing one degree of freedom to compensate load harmonic currents.…”

Because of the heavy use of electrical equipment, harmonic pollution is becoming more and more serious, which brings potential safety risks to our lives. In view of the fact that active power filters can effectively eliminate harmonics, an adaptive second-order sliding mode fuzzy control based on the backstepping method is proposed to eliminate harmonics in this article. The second-order sliding mode control can eliminate chattering in the system and results in a smoother controller. The uncertainties in the system are approximated by a fuzzy control system, and the adaptive laws are designed to ensure the stability of the system. Backstepping control can improve the stability and robustness of closed-loop systems. Simulation results show that the proposed method has better tracking effect, strong robustness, and stability and can effectively eliminate harmonics.

“…Artificial intelligence‐based PLL have also been proposed, however their relative high complexity may not suit the control of RES inverters [19, 20]. One of effective methods for single‐phase PLL is the second‐order generalised integrator based (SOGI‐PLL) [21, 22]. SOGI‐PLL produces accurate phase estimation for harmonics free grid voltage, but when the grid voltage is polluted with harmonics, its performance is negatively affected [23, 24].…”

An accurate, robust and efficient transport-delay based phase-lock loop (TDPLL) algorithm is proposed for single phase utility interactive inverters. The traditional TDPLL has low complexity and its transient response is smooth, but its performance is significantly affected by the change in the grid frequency. The proposed TDPLL is designed to have robustness against grid frequency variations. The proposed method uses two delays instead of one to cancel the grid frequency variation effect. Since the grid voltage could be polluted by harmonics and may suffer from sag/swell anomalies, the proposed method is enhanced further to be robust against these sources of disturbances. Moreover, a method is proposed to tune the parameters of the system. The performance of the proposed PLL is validated through simulations and experimental results.
