“…The algorithms for the reference current generation in the frequency domain are mainly based on Fourier analysis of the distorted load currents, which involves either fast Fourier transform (FFT) [20,21,106,[212][213][214] or, more frequently, discrete Fourier transform (DFT) [20,100,145,211,[215][216][217].…”

“…There are various techniques for the current control in SAPFs' systems (Table 2). The technique of current control through hysteresis controllers is one of the most used due to its simple implementation, good stability, accurate current tracking, rapid response in the transient regime, and robustness to the variation of the load parameters [2,39,[44][45][46][47][48][49][50]65,102,104,106,108,109,121,127,128,152,160,240]. According to the hysteresis control technique, the error is centered in a predetermined hysteresis band, and when the error exceeds the hysteresis limits, the appropriate switching decision is made to control the error within the hysteresis band so that the reference current is followed faithfully (Figure 17).…”

“…The most common solution for the DC-voltage control in SAPF systems, with very good results, is the simple use of a correctly tuned PI controller [48,54,55,57,66,69,95,[100][101][102][103][104][105][106][107][108]. However, the PI controller also has drawbacks, such as sensitivity to unbalance and parameter variations and complexity of linear mathematical modeling for the controller design [31].…”

“…In the most common SAPF structures, which have a voltage source inverter, an important aspect for proper operation is keeping the voltage constant across the capacitor on the DC side of the inverter to cope with the power losses. In most cases, using a proportionalintegral (PI) controller is satisfactory [48,54,55,57,66,69,95,[99][100][101][102][103][104][105][106][107][108]. However, there are other types of controllers proposed in recent years in the literature, such as PI/fuzzy [49,109], fuzzy [49,87,110], PSO/PI [39], synergetic [111], bi-sliding mode PI [112], ANN [42], sliding mode [99,113,114], and capacitor energetic model-based controller [115].…”

The increasingly extensive use of non-linear loads, mostly including static power converters, in large industry, commercial, and domestic applications, as well as the spread of renewable energy sources in distribution-generated units, make the use of the most efficient power quality improvement systems a current concern. The use of active power filters proved to be the most advanced solution with the best compensation performance for harmonics, reactive power, and load unbalance. Thus, issues related to improving the power quality through active power filters are very topical and addressed by many researchers. This paper presents a topical review on the shunt active power filters in three-phase, three-wire systems. The power circuit and configurations of shunt active filtering systems are considered, including the multilevel topologies and use of advanced power semiconductor devices with lower switching losses and higher switching frequencies. Several compensation strategies, reference current generation methods, current control techniques, and DC-voltage control are pointed out and discussed. The direct power control method is also discussed. New advanced control methods that have better performance than conventional ones and gained attention in the recent literature are highlighted. The current state of renewable energy sources integration with shunt active power filters is analyzed. Concerns regarding the optimum placement and sizing of the active power filters in a given power network to reduce the investment costs are also presented. Trends and future developments are discussed at the end of this paper. For a rigorous substantiation, more than 250 publications on this topic, most of them very recent, constitute the basis of bibliographic references and can assist readers who are interested to explore the subject in greater detail.
