“…Berbagai teknik sudah dilakukan untuk memperbaiki harmonisa. Beberapa diantaranya adalah penggunaan filter aktif shunt hybrid satu phasa dengan control histeresis dan finite control setmodel predictive control (FCS-MPC) [4] [5], diketahui hasil THDi yang didapatkan dengan kontrol histerisis lebih besar dari basis FCS-MPC, akan tetapi percobaan pada beban linier dengan control histerisis menghasilkan perubahan arus amplitudo pada sistem sedangkan dengan basis FCS -MPC tidak mempengaruhi arus amplitudo sistem.

“…Berdasarkan standar IEEE 519-2014 bahwa untuk mendapatkan nilai standar maksimum THDi harus dilakukan perhitungan rasio hubung singkat (SCRatio) terlebih dahulu, diketahui bahwa SCratio transformator pada phasa R sebesar 46,58; phasa S sebesar 43,49; dan phasa T sebesar 48,77 maka batasan I THD yang diperbolehkan yaitu sebesar 8% sehingga diketahui bahwa I THD pada transformator melebihi standar. Pemanfaatan filter aktif untuk meredam harmonisa juga sudah pernah diaplikasikan sebelumnya seperti laporan pada jurnal [4][5][6] [7].…”

Harmonic distortion usually occurs due to the operation of excessive non-linearelectrical loads, this distortion can be reduced by utilizing an active harmonic filter which canusually be adjusted for reactive power on the filter. In this study, an analysis of reactive powersettings on the active filter was carried out to determine the efficiency value obtained byfollowing the IEEE 519 - 2014 THDi standard value of 8% for each phase. The results of theanalysis of the smallest reactive power setting but exceeding the transformer efficiency valuewhen the existing condition meets the IEEE 519 - 2014 standard is 40 % with the THDi value forthe R phase = 7, 54%, S = 7,74%, and T = 7, 37% obtained an efficiency value of 96, 31%.

“…Also, the use of APF/SHAPF in load imbalance conditions is carried out, using hysteresis control [20], IRPT [21], [22], SRF [23], [24], and fuzzy [25], [26]. The harmonic currents in this study were reduced through SHAPF with model predictive control (MPC) at a balanced load in three-phased three and four wires [27] and discussed in a separate article. The contribution of this research is the implementation of finite control set model predictive control (FCS-MPC) on an inductor capacitor passive filter (LC)-connected hybrid power filter with varying non-linear loads and its ability to overcome load imbalances.…”

<span lang="EN-US">This paper presents a harmonic reduction and load imbalance model in a three-phase four-wire distribution network. This model uses a hybrid active power filter, a passive inductor and capacitor filter, and an active power filter in the form of a three-phase, four-leg connected grid inverter. The switching of the voltage source converter on this filter uses finite control set model predictive control (FCS-MPC). Control of this hybrid active power filter uses model predictive control (MPC) with a cost function, comparing the reference current and prediction current with mathematical modelling of the circuit. The reference current is taken from the load current by extracting dq, and the predicted current is obtained from the iteration of the voltage source converter (VSC) switching pattern. Each combination is compared with the reference current in the cost function to get the smallest error used as a power switching signal. Modelling was validated by using MATLAB Simulink. The simulation results prove a decrease in harmonics at a balanced load from 22.16% to 4.2% and at an unbalanced load, reducing the average harmonics to 4.74%. The simulation also decreases the load current imbalance in the distribution network. Reducing the current in the neutral wire from 62.01%-0.42% and 11.29-0.3 A.</span>

“…In the first time, passive filters had been introduced to eliminate the current harmonic effects. However, these types of filters are highly sensitive to random variations in power system parameters and can cause resonances parallel according to the source impedance [7]. Active power filters have been developed to overcome the disadvantages of passive filters and to provide a more reliable and flexible compensation.…”

<p>The increasing integration of decentralized production from renewable energies on the electricity grids should contribute to improving the stability and quality of the energy produced. The main objective of this work is to prove how renewable energy sources can improve the quality of electrical energy in the grid. In particular, controlled by the oriented flux technique, a double - feed induction generator DFIG driven by a wind turbine is together used to produce active power to the electrical network and to compensate the currentharmonics generated by a non - linear load, which leads to improve the supplied energy quality. The Active filtering function consists first of all in identifying the current harmonics using the theory of instantaneous active and reactive powers quality (PQ). Then, the closed loop based on the fast terminal sliding mode control (FTSMC) control allows both the generator to follow the optimal operating point of the wind turbine and to compensate for the current harmonics. The analysis and simulation results using MATLAB/Simulink confirm the effectiveness and the limits of the proposed methods and also show the performances of the law control which provides flexibility, high precision and fast response.</p>
