“…However, when way #4 is applied, the placement of primary sensors at the source side allows the maximal level of the efficiency of voltage deviation correction to be reached compared with other algorithms and with the placement of such sensors at the PCC. It must be noted that the obtained results help to properly select a control way for shunt active filter control according to the given conditions of the filter's installation and application [48][49][50][51][52]. The obtained results have given an opportunity to develop the adaptive algorithm of the shunt active filter functioning under varied application conditions for automated power quality improvement.…”

“…An active filter is quite an expensive device and it should be rated to work not only under special conditions but under a wide range of conditions with minimal changes in Cdc, L, and Udc and regulator settings. Also, the presented ranges of selection of the parameters Cdc, L, and Udc help us to detect the possible decrease in the cost of the active filter while retaining the filters' operating efficiency [49][50][51][52].…”

The results of theoretical and experimental studies on the problems of effective application of shunt active filters for power quality improvement and electromagnetic compatibility ensuring were presented in this article. Based on the different theories and methods, the most effective and well-studied control algorithms of shunt active filters were determined and analyzed to ensure their effective application in distributed generation systems and combined power supply systems. Mathematical and computer simulation models of shunt active filters with different control algorithms in distributed generation systems and combined power supply systems were developed. According to the results of mathematical modeling and computer simulation, the dependences were detected, reflecting the influences of internal and external parameters on the factors, determining the efficiency of the correction of power quality indicators. The range of permissible changes in the parameters of shunt active filters by saving the required efficiency level of power quality correction was detected under varied power supply system characteristics, load parameters and also in hybrid structures. The adaptive algorithm of the shunt active filter functioning under varied application conditions for automated power quality improvement is developed on the basis

“…The average voltage across the capacitor must be maintained at a constant value. The causes of its variation are mainly the losses in the switches (in conduction and commutation), in the decoupling inductances Lf and the injection of the fundamental currents during the transient regimes [10][11][12][13]. In steady state, the source must provide active power equal to the power demanded by the load.…”

In a low-voltage electrical network, harmonics, reactive power, the current and voltage imbalance, and voltage dips have harmful effects on electrical equipments. To overcome these problems, the hybrid UPQC is proposed. This paper discusses the structure of passive filters, parallel active filters, serial and combines (UPQC) to study the compensation of all types of disturbances likely to appear in the grid. Furthermore, the aim of reducing the size, cost of UPQC is to improve the quality of electric power, making it in compliance with the new regulatory constraints, we proposed the hybrid UPQC which uses passive filters and a combination of active filters. To validate the proposed topology, several sags of source voltage have been applied, at the point of common coupling (PCC). The simulation results from MATLAB/Simulink are discussed to verify the proposed topology.

This paper is aimed to illustrate and expose the performance of single-phase voltage dynamic voltage restorer (DVR) control connected to the electrical distribution grid. This performance is easily expressed by compensating for the sags and the swells voltages, and regulating the voltage across the load by injecting a voltage component in series with the source voltage increased or decreased with respect to the source voltage the load-side waveforms are purely sinusoidal. The integration of serial and chopper converters makes the DVR capable of bidirectional power flow. The key to this topology is its ability to compensate for sagging and swelling of the voltage in the long run. The modeling of the DVR and the design of its controller is included in this document. Effectiveness of control systems and start-up sequence of DVR operation is verified by detailed simulation studies. The control method used in this work is based on the use of a booster chopper and two cascade loops to generate the PWM command to control the chopper. The effectiveness of the suggested method is confirmed by the MATLAB/SIMULINK® simulation results and some prototype experiments. These results show the capacity of the proposed DC link control.
