“…35 Some researchers suggest an experimental STATCOM that can mitigate 30% voltage reduction due to voltage sag. 36 In order to compare the results with the research results, the device is subjected to a 30% voltage sag. Figure 11 shows the experimental results during 70% voltage sag (30% voltage reduction).…”

This paper proposes the application of a current mode control on a static compensator (STATCOM). The proposed method uses constant switching frequency. Hence, dominant switching harmonics are filtered easily. This approach is also simple and does not need complex calculations. As a result, it will be an ideal candidate for the implementation of controllers or FPGAs. It should be noted that a single-phase five level reversing voltage (RV) inverter is selected for the STATCOM. The topology has superiorities over conventional multilevel topologies in terms of the control circuit, switching frequency, and the number of components. The simulation results by MATLAB/Simulink prove successful mitigation of voltage sag by the proposed approach. A prototype based on the proposed method is also developed and examined successfully to evaluate voltage sag mitigation. The harmonic spectrum of the STATCOM is also presented to illustrate the equipment compatibility with IEEE 519 harmonic standard.

“…The system consists of bidirectional DC-DC converter and two AC/DC converters for two-way operation. D--STATCOM is a shunt-connected power electronics based device, which is generally connected near the load at the distribution systems to mitigate power quality problems such as voltage sag, voltage swell and harmonics [20]. In general, D-STATCOM consists of four main parts, namely, voltage source inverter (VSI), LC filter, control circuit and DC source, as shown in Fig.…”

Growing world concern over greenhouse gas emission, the promises of efficient energy, the development of battery characteristics and falling of its prices have led to the rapid increasing adoption of EVs. The number of electric vehicles (EVs) on the road is expected to continue to increase during the next decades due to various factors such as the rapid progress in EV technology and decreasing battery prices The prolonged battery charging process, which is one of the main problems that affects the increased EV penetration, makes the fast-charging units more attractive and efficient option for the charging stations. In this study, a control strategy for a DC microgrid including electric vehicle fast charging station (EVFCS) and distributed generation units is presented to examine the impacts of EVFCS on the grid as well as their potential contributions to the system operation in the case of considering the vehicle-to-grid (V2G) technology. It is especially aimed to mitigate the voltage sag and swell problems by using the EV battery as a DC source of a distribution static compensator (D-STATCOM) device. Simulation studies in MATLAB Simulink/Sim Power systems show that considerable improvements can be achieved from the perspective of distribution system operation such as improved voltage quality and from the perspective of end users such as decreased charging durations.
