“…But the problem of the crowbar protection circuit is that the pulsation of the electromagnetic (EM) torque cannot be confined. Custom power protection devices such as dynamic voltage restorer (DVR) [20], [21], series GSC (SGSC) [22], [23], superconducting fault current limiter-magnetic energy storage (SFCL-MES) [24], and unified power quality conditioner (UPQC) [25] - [27] are proposed for AC DFIG-based WECSs, but they are not suitable for DC-DFIG-based WEC-Ss due to the architectural difference of the two systems. Various types of non-superconducting fault current limiters (FCLs) [28] - [30] and SFCLs [31], [32] also provide good hardware-based solutions, due to their advantages of low cost and straightforward structure.…”

The development of DC custom power protection devices is still in infancy that confines the sensitive loads integrated into medium-voltage (MV) and low-voltage (LV) DC networks. Considering the DC doubly-fed induction generator (DC-DFIG) based wind energy conversion system (WECS), this paper proposes a dual active bridge (DAB) based DC unified power quality conditioner (DC-UPQC) with the integration of superconducting magnetic energy storage (SMES) to maintain the terminal voltage of DC-DFIG and regulate the current flow. The principle of the proposed DC-UPQC has three parts, i.e., parallel-side DAB (PDAB), series-side DAB (SDAB), and SMES, used for the voltage compensation, current and power regulation, and energy storage, respectively. The circuit principle of the PDAB and SDAB and the modeling of SMES are analyzed in this paper. A DC dual control strategy is also proposed to deal with the DC voltage oscillation generated by the AC-side asymmetrical fault. A case study of DC-DFIG interfaced with DC power grid is carried out, integrated with the proposed SMES-based DC-UPQC to verify the high-power applications of the proposed structure. Finally, an experiment is implemented, and the results demonstrate the correctness of the theoretical analysis and the feasibility of the proposed structure.

“…The DVR performs the injection of a specific voltage and phase angle in series with a distribution line to generate a load voltage [42]. In addition, the DVR can operate in several compensation modes, such as inphase mode [43], pre-sag mode [44], energy optimized mode [45], and self-supported mode [46]. A superconducting magnetic storage energy-based DVR using d-q transform control performs well in the mitigation of voltage quality disturbances as it compensates for the transient voltage waveform.…”

Industries driven by electric power require controlled and improved power quality for the optimal exploitation of resources. However, certain crucial issues greatly influence power quality, causing monetary losses to both the utility and customers. Numerous custom power devices are available to compensate for power quality issues; however, these devices alter the parameters of the transmission and distribution systems. Hence, a dynamic voltage restorer (DVR) is adopted in this study, which mitigates voltage disorders by establishing the desired quality and voltage level demanded by any sensitive load. The DVR adopts a 3ϕ four-switch voltage-source inverter (VSI) that acts as a cost-effective solution with a reduced number of switches. The cuckoo search algorithm (CSA) was utilized in this study as it solves multiple optimization issues with ease of implementation. Because it is robust to variations in the system, it significantly aids in enhancing the efficiency of the DVR by compensating for the variations in voltage and minimizing the total harmonic distortion (THD). The entire work was verified in MATLAB/Simulink to demonstrate the effectiveness of the introduced technique in smoothing the distorted voltage. The proposed approach achieved an efficiency of 92.6%witha simulation THD of 2.8% and hardware THD of 2.95%.INDEX TERMS DVR, CSA, Power quality, voltage swell, injection transformer, voltage sag.

“…A dynamic voltage restorer (DVR) is utilized deal with PQ issues related to voltage. A voltage of a particular phase angle and magnitude is injected in series with the distribution line generate a rated sinusoidal load voltage [14], [15]. The voltage sag and swell issues are minimized by DVR, which in turn improves the consumption of energy; however, it demands control approaches for increasing the efficiency [16].…”

In the power distribution system, the Power Quality (PQ) is disturbed by the voltage sag and swells. The Dynamic Voltage Restorer (DVR) is used to enhance various PQ problems like voltage sag, swells, and Harmonics. The previous Intrinsic Space Vector Transformation (ISVT) control techniques with DVR system, to compensate the power quality issue. It produced a steady-state error, low efficiency, and high THD. The SMES based DVR has provided excellent results in overcoming these issues. The energy is stored by DVR through a storage element, which takes alternate energy from a Solar PV cell. The Maximum Power Point Tracking (MPPT) based P&O algorithm is implemented to equalize the solar power. The Voltage Source Inverter (VSI) generates the reactive power, which has to be compensated with the help of Pulse Width Modulation (PWM) and the feedback control loop are essential to enhance the injection of reactive power to the line. Due to this reason, a proposed Predictive Space Vector Transformation (PSVT) control-based DVR is implemented. It analyzes the variation of power on the distribution side and generates the proper feedback control to the inverter systems. In the instant of voltage injection to the line with the help of DVR, the phase angle mismatch happens which is not synchronized reactive power to the grid. Due to the non-synchronization of reactive power, more harmonic distortion is generated. A Proportional Resonant (PR) controller is introduced, which is Proportional Resonant (PR) current controller. The current injected by the inverter into the grid in phase with the grid voltage maintain constant with unity power factor. The PR controller design is cascaded with a harmonic compensator to mitigate low order odd harmonic components present in the output current of VSI and minimize the total harmonic distortion (THD). The performance of the proposed is evaluated using MATLAB 2017b software.
