“…As the trend of increasing in research of renewable energy applications, researchers are progressively developing new topologies and algorithms in designing MLI in which the fruits of the research can also be applied in APF by replacing the conventional six-step three-phase inverter as shown in Figure 1(a). The advantage of using MLI compare to conventional six-step inverter is its capability to produce low harmonic output current which at the same time improving the performance of APF [5,[11][12][13][14][15]. Furthermore, MLI can produce high efficiency for fundamental frequency, is capable to work under high switching frequency, and can reduce voltage stresses across switches, which make it to even perform in medium and high voltage application [5,[11][12][13]15].…”

“…Furthermore, MLI can produce high efficiency for fundamental frequency, is capable to work under high switching frequency, and can reduce voltage stresses across switches, which make it to even perform in medium and high voltage application [5,[11][12][13]15]. There are three common types of MLI namely Cascaded H-Bridge (CHB), Neutral Point Diode Clamped (NPC) and Flying Capacitor (FC) [11,12,14,15]. Among them, the CHB is the most popular due to its advantages such as less power devices requirement, Simple design and possible to produce output voltage level more than twice the number of DC source.…”

<span lang="EN-US">Multilevel inverter (MLI) becomes more significant in Active Power Filter (APF) application due to capability to its produce low harmonic output current in which at the same time improving performance of APF. Among the topologies of MLI, Cascaded H-Bridge (CHB) is the most popular topology with less power devices requirement and simple design. MLI CHB is also capable to produce possible output voltage at twice of the number of DC source which in this case of APF is the best suited topology to replace with the conventional six -step inverter. This paper presents the performance of three- phase three-wire CHB MLI used in Shunt Active Power Filter (SAPF) based on Direct Current Control (DCC) and Indirect Current Control (ICC) schemes. Both schemes are developed and verified in MATLAB/Simulink. The simulation results show that both current control algorithms are capable to mitigate load current with Total Harmonic Distortion below than the permissible value based on IEEE 519 standard.</span>

“…The former has shown effectiveness against harmonics against nonlinear loads. Kamala et al (2018) conducted a study to improve the quality and dependability of the power supply in petrochemical industries using Active Power Filters (APF). However, the cases of unbalanced loads were not considered in all these contributions cited above.…”

In recent years, power quality has become a major concern for electric network managers. Active filtering control schemes ensure improved power quality of the electric network and are able to maintain a desired voltage level at the point of connection, regardless of the current absorbed by nonlinear loads. Harmonics can cause vibrations, equipment distortion, losses and sweatiness in transformers. The main objective of this work is to enhance the quality of energy in a microgrid consisting of 100 kW photovoltaic (PV) system and a 50 kW battery storage connected to nonlinear and unbalanced loads. This paper proposes a the four-arm parallel active filter with a on Proportional-Integral (PI) controller to mitigate the harmonic problems in a microgrid. In addition, an algorithm has been designed to eliminate the neutral current. The identification function is one of the most particular approach for extracting harmonics, it involves providing a current reference imposed by the active filter in order to carry out the filtering operation. Both the performance and the quality of the current harmonic compensation's depend strongly on the strategy adopted for the generating the current reference. In this work, the instantaneous power strategy p-q is chosen outstanding the simplicity and effectiveness in implementation. The proposed control strategy has been tested under simulations and the results have shown good tracking of the references and a significant reduction in the Total Harmonic Distorsion (THD) level under highly unbalanced conditions of the nonlinear loads. The current THD is reduced from 43.64 before filtering to 3.74% after the application of the four-arm filter, following the recommendations of IEEE-519 standard (THD less than 5%).
