“…The output of the PI controller represents the magnitude of the real power current, which is normally proportional to the inverter loss. To generate real power current reference signal, the real power current magnitude is multiplied with normalized grid voltages to form the real power current reference signals [13].…”

A decentralized control strategy is proposed to coordinate multiple shunt active power filters (APFs) to improve power quality at the point of common coupling (PCC) in terms of power factor correction and harmonic elimination. Under the proposed control strategy, each APF uses locally measured current signals to decide the amount of power quality improvement task, which is limited to its power rating. In this way, the overall power quality improvement task is automatically distributed to the APFs without control communications. Simulation results verify the performance of the proposed control strategy.Index Terms--Distributed operation, multiple shunt active power filters, power quality improvement capacity.

“…In order to achieve good filtering performance, the compensating current reference generation of the active power filter must be accurate. The control system of the active power filter [9], [13] is answerable for real time instantaneous compensating current reference. The most important task of the control system is to produce the compensating phase currents opposite to the harmonics in the load phase currents, and the compensating neutral current opposite to the load neutral current and also used for removing the load phase imbalance as well as for compensating the reactive power drawn by the load, in which case the active power filter injects the compensating current for the fundamental negative sequence load current component and produces the reactive power required by the load.…”

“…The proposed scheme employed current controlled voltage source active power filter which has been found realistic and excellent to the compensation characteristics of current unbalance and neutral current in three phase four wire system. This paper presents the technique with the load current detection method as a suitable method controlling directly the output current of active power filter hence called direct current control (DCC) and requires a simple design for control stability [8], [9]. The control of switching frequency is described with introducing hysteresis band current control algorithm [10], [11], [12] to force the current of the filter to track their reference value.…”

In this paper two topologies of current controlled voltage source inverter (CCVSI) based active power filter using direct current control technique for compensating unbalanced loads in a three-phase four-wire system is proposed. In this method the harmonic compensation current reference is generated without introducing any additional harmonic extraction filtering circuits. A control approach for balancing the DC voltage of the active power filter is incorporated to cover the system losses. The proposed shunt active power filter compensates harmonics and reactive power in all three phases as well as the neutral current. To regulate and balance the dc capacitor voltage, a current control method using hysteresis controller is proposed. The simulation results based on MATLAB\Simulink tool demonstrate the feasibility of the proposed topologies. The total harmonic distortion of source current has been calculated and compared for two topologies to demonstrate important compensation characteristic of proposed control methodology of shunt active power filter.

The compensating currents or active filter currents are represented by i ( ) .…”

This paper presents a novel harmonic identification algorithm of shunt active power filter for balanced and unbalanced three-phase systems based on the instantaneous power theory called instantaneous power theory with Fourier. Moreover, the optimal design of predictive current controller using an artificial intelligence technique called adaptive Tabu search is also proposed in the paper. These enhancements of the identification and current control parts are the aim of the good performance for shunt active power filter. The good results for harmonic mitigation using the proposed ideas in the paper are confirmed by the intensive simulation using SPS in SIMULINK. The simulation results show that the enhanced shunt active power filter can provide the minimum %THD (Total Harmonic Distortion) of source currents and unity power factor after compensation. In addition, the %THD also follows the IEEE Std. 519-1992.
