“The increased penetration of Distributed Energy Resources (DER) is inspiring the entire design of conventional electrical power system. “A Microgrid (MG) includes distributed generation, loads, energy storage, and a control system that is competent of working in grid-connected mode and/or islanded mode. Power quality (PQ) problems are one of the major technical challenges in MG power system. To get better PQ of energy supply, it is essential to analyze the harmonics distortion of the system. Moreover, harmonic distortion in a MG networks has significantly reduced PQ, which affects the stability of the system. In order to diminish the harmonics, shunt active power filter (SAPF) has been extensively useful and it is verified to be the best solution to current harmonics. The present paper proposes the mitigation of harmonics of a MG system using shunt active power filter (SAPF). However, the SAPF is employed for reimbursing the harmonics concurrently in the distribution system. The proposed model is developed in MATLAB/Simulink and the result obtained validates the superiority of proposed technique over others in terms of harmonics elimination.”

Shunt active power filter (APF) is an electric equipment which effectively optimizes harmonic waves. By measuring the load current, it produces compensated current with opposite amplitude to the load current in order to improve the power quality of the power grid. Little has been reported on how to effectively design the LPF employed in the link of shunt APF and power system. The paper theoretically analyzes constrains for parameters of the LCR output filter, and then determines the optimal LRC filter parameters by comparing different output filter (OF) functions. At last, the experiment results further verify the correctness of the design method.

This paper presents the fuzzy logic controller for shunt active power filter used to compensate harmonic distortion in a three-phase system. The shunt active filter employs a simple method for estimating the reference compensation current. A fuzzy logic based current control strategy is used to regulate the filter current and hence ensure harmonic free supply current. Classic filters may not have satisfactory performance in fast varying conditions. However, an auto-tuned active power filter gives better results for harmonic minimization and power factor improvement. The proposed fuzzy based shunt active filter maintains the THD well within IEEE-519 standards. The validity of the presented approach in harmonic mitigation is verified by simulation results in MATLAB/ Simulink and hardware prototype.

The shunt active power filter (SAPF) is an effective means for the modification of power quality. However, the compensation performance of SAPF would be deteriorated when the unbalanced nonlinear loads are present in the power system. To enhance the compensation performance of SAPF, the adaptive frequency-based reference compensation current control strategy is proposed in this paper. The proposed solution procedure can be divided into three stages including adaptive frequency detection, phase synchronization, and adaptive compensation. With the tracking of power system frequency, the phase synchronization for the SAPF compensation can be effectively modified under the power variation of unbalanced nonlinear loads. Based on the correct synchronization phase angle, the reference compensation current of SAPF can be accurately obtained with the adaptive linear neural network (ALNN) in the stage of adaptive compensation. In addition, the direct current (DC)-link voltage of SAPF can also be effectively regulated to maintain the compensation performance. To verify the effectiveness of the proposed adaptive frequency-based reference compensation current control strategy, the comprehensive case studies implemented with the hardware-in-the-loop (HIL) mechanism are performed to examine the compliance with the specification limits of IEEE Standard 519-2014. The experimental results reveal that the performance of proposed SAPF control strategy is superior to that of the traditional instantaneous reactive power compensation control technique (p-q method) and sliding discrete Fourier transform (DFT).

Active power filter, a good alternativeforeasing power quality problems. APF can provide an effective solution for the removal of hormonic current present in power system. The performance of shunt APF depends on technique used to generate reference current, controlling method used and topology of inverter under consideration. In this paper a fuzzy logic-based control scheme was presented to generate reference signal for hysteresis current controller of three phase VSI. Unit template based control algorithm for control signal generation and fuzzy logic controller was used to replace PI controller to improve performance. The proposed system is very much capable in maintaining and improving power quality at distribution side. The shunt APF performance was analysed with SIMULATION model under balanced condition and outcome obtained satisfactory in improving the power quality.
