“…Further composite topologies for universal active filters are presented in order to demonstrate how generic designs for filter networks can be obtained. The presented approach can also be used for designs considering to reduce the number of sensors, providing results that are similar to the sensorless proposals described in [9,10,28], and exhibiting a quite good compromise between costs and robustness.…”

“…As an alternative, the compensators in a synchronous reference frame can be converted into a stationary frame, which results in resonant compensators [23][24][25][26]. However, there is a clear necessity for frequency adaptation in these compensators, since the design is conceived for the nominal grid frequency [1,[25][26][27], whereas solutions for adaptive resonant schemes are presented in [25][26][27], quasi-resonant compensators are proposed in [9,10,28] for providing robustness against grid frequency variations by adjusting the selectivity. In [1], a solution was proposed using adaptive quasi-resonant compensators to further improve the performance of selective harmonic mitigation.…”

This study presents a general control strategy for active power filters derived from the current-shaping principle previously employed in shunt active filters. The generalisation introduced here and denoted as voltage-current shaping control, exploits the symmetry between the possible wave-shaping solutions, and can be applied to shunt, series, and more complex networks of active filters. Moreover, the proposed generalisation allows the synthesis of specific control schemes with a reduced number of sensors. The relevant properties of the proposed schemes in the application of harmonic mitigation are determined. Further, a discussion of the integration of multiple quasi-resonant schemes is presented. Using this approach, it is possible to fine-tune the mitigation of specific components in the harmonic profile from the voltages or currents in the circuit. Experimental results obtained from using a 1 kVA prototype are presented to support the proposed generalisation.

“…Fig. 1-b is a simple display of shunt active power filters, as it is shown APF is compensating the nonlinear load current by injecting the same nonlinear current that load absorbs from the grid, so that the grid current will be sinusoidal [66,67] Ongoing researches in this field are concentrated over novel control methods of shunt active power filters and also new applications for shunt APFs [68][69][70][71][72][73][74][75][76][77][78][79][80]. More detailed analysis of main topologies of shunt active power filters is done in [81].…”

-It is obvious that power quality is an important characteristic of today's distribution power systems as loadsbecome more sensitive on the other hand nonlinear loads are increasing in the electrical distribution system. Considering the distributed nature of harmonic loads, the need for distributed power quality improvement (PQI) is inevitable. From years ago, researchers have been working on various kinds of filters and devices to enhance the overall power quality of power system, but today the nature of distribution system has been changed and power electronic based DGs play an important role in distribution grids. In this paper, a thorough survey is done on power quality enhancement devices with emphasis on ancillary services of multi-functional DGs. A literature review is also done on microgrids concept, testbeds and related control methods. Although there were some applications of DGs for PQI improvement these applications were not defined multi-functional DGs. Various control methods are studied and categorized regarding different viewpoints in the literature. Finally, a couple of thorough comparisons are done between the available techniques considering the nature, capabilities, advantages and implementation costs.
