Abstract The manuscript proposes a Particle swarm optimization (PSO)-based shunt active filter (SAF) approach for power quality (PQ) improvement by eliminating the harmonics. To selective eliminate the harmonics, the detailed model and operation of three-phase 4-leg-based SAF is proposed by considering the neutral current. The proposed inverter is operated by using improved instantaneous power theory (IPT) and the pulses of the inverter are generated by using the hysteresis band controller (HBC). In the proposed approach, to extract the appropriate fundamental component and controlling the dc-link voltage (V dc ) of SAF, an artificial intelligence (AI) technique termed as particle swarm optimization (PSO)-based Proportional integral (PI) controller (PI-PSO) is implemented. The optimal performance of the proposed model is tested by using MATLAB software. To justify the versatility of the proposed approach, PI-PSO-based SAF outcomes are related to differential evolution (DE) optimization technique.

1 Introduction Recently, to attain high efficacy, controllability, and flexibility in the power system, real-time systems are designed by using power electronic-based components. However, the components such as a converter, inverter, and rectifiers show nonlinear and unbalanced features like voltage and current signals. Similar to the above, other electronic devices such as fax machines, printers, the programmable logic controller (PLC), refrigerators, and computers draw distorted currents which increases in the B.

sensitive load applications in the real power sector [1, 2]. Sensitive loads are divided into two categories such as current and voltage imbalanceS. With increasing the number of sensitive loads, problems like low efficiency, decrease in power factor, generation of harmonics, disruption of reactive power, etc.S are damageable to AC power lines [3, 4]. The increase in nonlinear loads affects the nearby clients, opposition to close communication systems, and also increases the temperature of the appliances. The consequence of this nonlinearity increases considerably in recent years. Therefore, it is important to rethink the control strategies and filter operation for the improvement of power quality. Generally, the power quality problems are eliminated by u
