“…In order to overcome some of the crowbar problems, a method using a chopper to regulate the DFIG DC link was proposed in [14,15]; however, it resulted in a circulation of high current in the rotor side converter (RSC) during utility disturbances. Shunt capacitors and STATCOMs have been proposed to enhance LVRT [16][17][18][19], but they cannot effectively deal with unsymmetrical faults. In [19], an LVRT enhancement strategy using DVR is proposed in [19], yet it suffers from increased control complexity and mathematical calculations.…”

Some of the major challenges facing micro-grids (MGs) during their connection with the utility grid are maintaining power system stability and reliability. One term that is frequently discussed in literature is the low-voltage ride-through (LVRT) capability, as it is required by the utility grid to maintain its proper operation and system stability. Furthermore, due to their inherent advantages, doubly fed induction generators (DFIGs) have been widely installed on many wind farms. However, grid voltage dips and distortion have a negative impact on the operation of the DFIG. A dynamic voltage restorer (DVR) is a commonly used device that can enhance the LVRT capability of DFIG compared to shunt capacitors and static synchronous compensator (STATCOM). DVR implements a series compensation during fault conditions by injecting the proper voltage at the point of common coupling (PCC) in order to preserve stable terminal voltage. In this paper, we propose a DVR control method based on the adaptive noise cancelation (ANC) technique to compensate for both voltage variation and harmonic mitigation at DFIG terminals. Additionally, we propose an online control of the DC side voltage of the DVR using pulse width modulation (PWM) rectifier to reduce both the size of the storage element and the solid-state switches of the DVR, aiming to reduce its overall cost. A thorough analysis of the operation and response of the proposed DVR is performed using MATLAB/SIMULINK under different operating conditions of the grid. The simulation results verify the superiority and robustness of the proposed technique to enhance the LVRT capability of the DFIG during system transients and faults.

“…Therefore, grid codes have been established in many countries to comply with the new requirements. Since voltage fluctuation is a common power quality problem in power systems, most of studies are focused on the performance of WTGs during voltage sag [5][6][7]. Although it is a less power quality problem, voltage swell may also lead to the disconnection of WTGs from the grid.…”

Variable speed wind turbine generators installation has been significantly increased worldwide in the last few years. Faults at the grid side may call for the disconnection of the wind turbine from the grid as under such events, wind turbine generator (WTG) may not comply with the recent developed grid codes for wind energy conversion systems (WECS). In this paper, a unified power flow controller (UPFC) is applied to improve the fault ride through (FRT) capability of doubly fed induction generator (DFIG)-based WECS during voltage swell and voltage sag at the grid side. Simulation is carried out using MATLAB/Simulink software. Results show that UPFC can effectively improve the FRT capability of DFIG-based WECS and hence maintaining wind turbine connection to the grid during certain levels of voltage fluctuation at the grid side.

“…Furthermore, the growing development of RES has led to a change in the requirements of reactive power support services [33]. STATCOM is demanded to support reactive power continuously during asymmetrical grid faults in order to control grid voltages and to enhance fault ride-through capability of RES [34]- [35]. In addition, delta-connected STATCOM exhibited several characteristics compared to conventional two-level converters, and the reactive power control strategies proposed in [14]- [16] are not suitable in this case.…”
