Industry 4.0 technology is growing rapidly in the manufacturing industry and other businesses. Devices used in Industry 4.0 are manufactured with high frequency switching functions and generate harmonics that negatively affect power quality. Choosing the direct or parallel connection method of the harmonic current absorber depends on the specific requirements of the system and the goal of improving power quality. Shunt Active Power Filter (SAPF) is the best device currently used to improve power quality. This study proposes to use the fuzzy-rough MARCOS method to make decisions on SAPF selection based on experts' opinions to improve the quality of power sources at the source of smart manufacturing plants using Industry 4.0 devices. This study implements two decision-making methods in Multi-Criteria Decision-Making (MCDM). The first is the SWARA method (Stepwise Weight Assessment Ratio Analysis), and the second is the MARCOS method (Measurement Alternatives and Ranking According to Compromise Solution). The fuzzy-rough method is used to incorporate uncertain information into the results of decisionmaking and to use linguistic values. The analysis results of the fuzzy-rough SWARA method show that the price factor and power filter range have the greatest influence on the choice of SAPF for harmonic mitigation. Analysis results from the fuzzy-rough MARCOS method show that manufacturer Schneider Electric has the best features according to the evaluation results from decision makers. Sensitivity analysis methods were used to confirm the findings. The harmonic value THDi displayed in the field after installing the harmonic filter is, respectively, THDi1 = 5%, THDi2 = 6%, and THDi3 = 5%, it meets the regulations of Circular 30/2019/TT-BCT. According to this circular, the requirement for total harmonic value (THDi) is below 12%. With THDi1, THDi2, and THDi3 values all below 12%. In operating electrical systems in production and business environments, using SAPF filters for harmonic mitigation helps improve power quality. The fuzzyrough method is applied, and the decision maker's decisions are used to adjust the intention to use the SAPF set to suit the conditions. INDEX TERMSShunt Active Power Filter, fuzzy-rough MARCOS, Harmonic Mitigation, Power Quality I. INTRODUCTION As Industry 4.0 technology continues to develop, switching devices are also growing exponentially to meet the development of Industry 4.0 technology [1]. Switching devices generate noise signals, called harmonic currents. Harmonic currents arising in the power source cause complex effects and cause the quality of the power source to deteriorate. Devices that use electricity have poor power quality due to harmonic currents, making the device's operation unstable, possibly exploding, and unstable performance [2]. The development of Industry 4.0 technology is not only in the manufacturing industry, but Industry 4.0 technology is developing and penetrating all industries, Electrical equipment in industries that use Industry 4.0 technology is affected by harmo...

“…There are many methods to remove harmonics or minimize harmonics in single-phase power such as using a Passive Power Filter (PPF) using an Active Power Filter (APF) (Luciano and Joan, 2020; Radek et al, 2013; Rajalakshmi and Rajasekaran, 2016) and using a Hybrid Power Filter (HPF). However, the Shunt Adaptive Power Filter (SAPF) (Radek et al, 2020;Radek et al, 2019;Martinek et al, 2019) was chosen to be used for this study because of its effective flexibility in removing harmonics, in addition, SAPF is also easy to apply in combination with existing control algorithms. such as nature optimization or inspired optimization, in this study, the combination of particle swarm optimization (PSO) algorithm with SAPF is used to control the offset current (Ic) from the reference current of the PSO algorithm to compensate for the current loss due to harmonics generated on the singlephase power supply.…”

Purpose – These load sources are the main cause of generating harmonics, generating power loss in the transmission system and electrical equipment system, as well as reducing the life of electrical equipment, reducing the accuracy of electrical measuring devices, and reducing the signal transmission of communication devices. Methodology/Approach – This study applies the Particle swarm optimization (PSO) algorithm to DC-link capacitor voltage control based on the Proportional-integral (PI) control algorithm to determine the reference current. MATLAB/Simulation 2019a is used to simulate research results. Findings – The harmonic compensation performance of the SAPF circuit gives good results and meets the standard for total harmonic distortion (THD) of less than 5%. Originality/Value of paper – Bridge rectifiers with RL load and Non-linear load with active RC are applied in a single-phase power supply. The single-phase voltage source inverter is used to shunt the adaptive power filter (SAPF) to compensate for reactive power and current harmonics.

“…The Shunt Active Power Filter (SAPF) is essentially a controlled current generator that injects the current into the part of the electrical circuit being compensated in parallel, via the coupler [18]. The control unit contained in the filter uses a current sensor to measure the instantaneous current waveform that is processed in the control unit by a suitable algorithm.…”

This study focuses on the design of a measuring system for monitoring the power quality within the SMART street lighting test polygon at university campuses with relation to testing an adaptive current control strategy for three-phase shunt active power filters. Unlike conventional street lighting, SMART elements are powered 24/7. Due to the electronic character of the power part of such mass appliances, there are increased problems with the power quality of the electric energy. Compared to the current concept of street lighting, there is a significant increase in the content of higher current harmonic components, which cause several problems in the distribution system. The test polygon contains 16 luminaires made by various manufacturers and mounted with various SMART components. Using the polygon control and monitoring system, dynamic load scenarios were selected. These scenarios tested the possibilities of different adaptive current control strategies for three-phase shunt active power filters to improve the power quality of electricity. This study focuses on three adaptive algorithms that respond to dynamic changes of current harmonics level in real-time. The possibility of active filter control was tested using FPGA, mainly due to the low latency of the filter control part.
