Due to increased level of harmonic pollution in present day power system, power quality conditioning has become indispensable, and therefore, various power conditioning techniques were introduced. Among them, active power filters appear to be the most viable device used for mitigating power quality issues. Various strategies of controlling active power filter are proposed and implemented by researchers and engineers in aim of achieving near perfect compensation. This paper presents a comprehensive review of state-of-art control strategies of active filters. Various strategies are discussed and compared in terms of implementation and performance.

“…The instantaneous symmetrical component theory method, the sample and hold circuit method, and the d-q transformation based method are also used for the calculation of the reference compensation currents [18][19][20]. Single-phase pq theory was proposed for single-phase active power line conditioners [21].…”

This paper discusses harmonic current compensation of the constant DC-capacitor voltage-control (CDCVC)-based strategy of smart chargers for electric vehicles (EVs) in single-phase three-wire distribution feeders (SPTWDFs) under nonlinear load conditions. The basic principle of the CDCVC-based harmonics compensation strategy under nonlinear load conditions is discussed in detail. The instantaneous power flowing into the three-leg pulse-width modulated (PWM) rectifier, which performs as a smart charger, shows that the CDCVC-based strategy achieves balanced and sinusoidal source currents with a unity power factor. The CDCVC-based harmonics compensation strategy does not require any calculation blocks of fundamental reactive, unbalanced active, and harmonic currents. Thus, the authors propose a simplified algorithm to compensate for reactive, unbalanced active, and harmonic currents. A digital computer simulation is implemented to confirm the validity and high practicability of the CDCVC-based harmonics compensation strategy using PSIM software. Simulation results demonstrate that balanced and sinusoidal source currents with a unity power factor in SPTWDFs are obtained on the secondary side of the pole-mounted distribution transformer (PMDT) during both the battery-charging and discharging operations in EVs, compensating for the reactive, unbalanced active, and harmonic currents.

“…Some control strategies in these active power line conditioners are based on active-reactive instantaneous power theory, which was originally proposed by Prof. H. Akagi [1]- [5]. The instantaneous symmetrical component theory method, the sample and hold circuit method and dq transformation based method are also used for the calculation of the reference compensation currents [6]- [8]. All these control strategies require a significant number of computation steps.…”

This paper proposes a novel, simple reactive power control strategy for the active load balancer (ALB) in three-phase four-wire distribution systems. The proposed reactive power control strategy may is applicable for adjustment of the sourceside power factor under the balanced load condition. Only DC capacitor voltage control is used in the proposed control strategy. Therefore, the calculation blocks of the active and reactive components of the load currents are not necessary. The authors, thus, offer the simplest control strategy to control reactive power under the balanced load condition on three-phase fourwire distribution feeders. The basic principle of DC capacitor voltage control based reactive power control strategy is discussed in detail, and then confirmed by digital computer simulation. A prototype experimental system was constructed and tested. Experimental results demonstrate that balanced source currents with reactive power control are achieved on three-phase four-wire distribution feeders. These experimental results also demonstrate that controlling the reactive power reduces the required power rating of the ALB compared to that of the conventional unity power factor control strategy.Index Terms-Active load balancer, reactive power control, constant DC capacitor voltage control, instantaneous activereactive power theory, three-phase four-wire distribution systems.
