“…Shunt APFs have been also used to reduce harmonics. They can be regarded as a kind of current source compensating for the harmonic current resulting from nonlinear loads [40]. Nevertheless, the cost of shunt APFs is relatively high, and they are not preferable for large-scale systems, because the power capacity of the filter should be directly proportional to the load current to be compensated.…”

Multi-functional voltage source inverters (VSIs) have attracted increasing attention in recent years for their advantageous auxiliary services for power quality enhancement in autonomous microgrids. These types of VSIs can not only achieve a proper control scheme in autonomous mode but also cope with the prescribed power quality and stability requirements. These functionalities are integrated within the same device, thereby significantly improving the cost-effectiveness of microgrids while decreasing the investment and bulk compared with those of multiple devices with independent functionalities. Control strategies for power quality enhancement in autonomous microgrids using multi-functional VSIs are comprehensively reviewed in this paper. In addition, such VSIs are discussed in detail, and comparisons of which are also provided. Lastly, a number of future research directions for multi-functional VSIs are recommended.

“…These problems could be solved by the help of shunt active power filters, which are regarded as a kind of current source compensation for the harmonic current due to nonlinear loads [2], [3]. Nevertheless, the cost of shunt active filters is relatively high, and they are not preferable for a large-scale system since the power capacity of the filter is directly proportional to the load current to be compensated.…”

This paper proposes a coordinated control method, for static series compensator (SSC) equipped with shunt passive filters, to compensate grid voltage disturbance (sag, swell, voltage interruption and flicker) and load current harmonics. To effectively extract the positive-sequence component of the grid voltage, digital all-pass filters are implemented. These filters can deliver a preferred phase shift and no magnitude drop, unlike conventional low or high-pass filters. According to the extracted positive-sequence component, the angle of the grid phase and the reference voltage for compensation are obtained. This technique can improve the grid voltage stability and mitigate the load current harmonics as well. PSCAD/EMTDC simulations show the usefulness of the proposed technique.

“…Since their basic operating principles were firmly established in the 1970s [1][2][3][4][5], active harmonic filters -active filters, 1 for short -have attracted the attention of power electronics researchers/engineers who have had a concern about harmonic pollution in power systems [6][7][8][9][10][11][12][13][14]. Moreover, deeper interest in active filters has been spurred by -the emergence of semiconductor switching devices such as IGBTs (insulated-gate bipolar transistors) and power MOS-FETs (metal-oxide-semiconductor field-effect transistors), which are characterized by fast switching capability and insulated-gate structure, -the availability of digital signal processors (DSPs), fieldprogrammable gate arrays (FPGAs), analog-to-digital (A/D) converters, Hall-effect voltage/current sensors, and operational and isolation amplifiers at reasonable cost [15][16][17][18][19][20][21][22].…”

Unlike traditional passive filters, modern active filters have the following multiple functions; harmonic filtering, damping, isolation and termination, reactive-power control for power factor correction and voltage regulation, load balancing, voltage-flicker reduction, and/or their combinations. Significant cost reductions in both power semiconductor devices and signal-processing devices have inspired manufactures to put active filters on the market. This paper deals with general pure active filters for power conditioning, and specific hybrid active filters for harmonic filtering of three-phase diode rectifiers, as well as traditional passive filters.
