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...

“…Having the capability to resolve multiple power quality issues simultaneously, the UPQC is the most comprehensive APF that can be employed [7]. UPQC does not compensate only for the short-term voltage disruptions and variations but also improves Total Harmonic Distortion (THD) and decreases losses by canceling out voltage and current harmonics and compensating for reactive power [8,9]. It is the integration of shunt and series APFs through a common DC link capacitor.…”

This paper presents novel Unified Power Quality Conditioner (UPQC) system based on seven-level Neutral Point Clamped (NPC) inverter using combined PD-SPWM and fuzzy control scheme. The proposed UPQC is adopted to mitigate source current harmonics and compensate all voltage disturbances simultaneously. It is designed by the combination of series and shunt Active Filters (AFs) connected by a common DC link capacitor. The DC voltage at common DC bus is maintained constant using proportional integral voltage controller. The Synchronous Reference Frame (SRF) method is used to get the shunt APF reference signals and the power reactive theory (P-Q theory) for the series APF. Conventional control schemes require complex calculations, the use of intelligent systems help to reduce the control system size and the operation complexity. The shunt and series Active Power Filter (APF) reference signals derived from the control algorithm are injected in Fuzzy intelligent controllers to generate switching signals. The functionality of proposed UPQC system and its control system is evaluated using Matlab-Simulink software and SimPowerSystem Toolbox under various operation conditions in cases of most common power quality problems such as voltage sag, voltage swell, current harmonic compensation of nonlinear loads and unbalanced load. The simulation results show UPQC performances to improve the power quality in steady and transient conditions operation at the point of common coupling on power distribution under unbalanced and distorted voltage conditions.
