“…The extensive swing of unbalanced voltage of the grid can severely affect the role of a grid-connected inverter and PV module, due to the high current harmonics and power ripples. Various FRT strategies have been proposed to maintain the LVRT capability of PVS above the E. ON curve to handle this problem [14][15][16][17][18][19][20][21][22]. Some FRT strategies have improved the power quality considerably, such as minimizing ripples but compromising at high currents, and vice versa [14,15].…”

This paper presents the design and analysis of a proportional resonant controller with a resonant harmonic compensator and switch-type fault current limiter, as a fault-ride through strategy for a three-phase, grid-connected photovoltaic (PV) system under normal conditions and asymmetrical faults. The switch-type fault limiter comprised of current-limiting inductors, a bridge rectifier, a snubber capacitor, linear transformers, and energy absorption bypass. Furthermore, a critical and analytical comparison of switch-type fault limiters is carried out, with the conventional crowbar as the fault-ride through strategy, in combination with a conventionally tuned proportional integrator controller. The designed fault-ride through strategies with proportional integrator and proportional resonant controllers with resonant harmonic compensators are tested at the point of common coupling of the photovoltaic system and at a distance of 19 km from the point of common coupling, in order to analyze the impacts of fault parameter with respect to location. A MATLAB/Simulink model of a 100 kW three-phase grid-connected photovoltaic system is used for analysis. The simulation results of the proposed switch-type fault limiter with proportional resonant controller effectively validate the stable, ripple-free, and robust response compared to all other configurations. In addition, it is also verified that the grid faults on the PV system have a significant impact on fault type, and less impact on fault location.

“…Due to failure of rotor converter, DFIG completely loose the control. The destabilised DC-link voltage decreases the life of capacitor and reduces the efficiency of converters [7][8][9]. Due to the large share of WT in supplying electric power to the grid, DFIG must stay connected to the grid in case of fault to fulfill requirement of grid code.…”
