“…The APF, shunt hybrid active power filter (SHAPF), and current decomposition reduce harmonics, reactive power, and load imbalance. 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.…”

<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>
