“…However, the incorporation of renewable energy sources into the grid has lowered the energy dependencies on conventional sources, which causes pollution. Wind energy is the most reliable renewable energy source and has a significant share of the total energy generation . Wind energy conversion systems (WECS) are predominantly categorized into fixed speed wind turbine‐based WECS and variable speed wind turbine‐based WECS.…”

Over the last few decades, doubly fed induction generators (DFIG) have become one of the most successful and preferred types of wind energy generators (WEG). The DFIG has the advantages of a wide range of speed operations, a high efficiency, and partial rated converters. However, direct coupling of the stator with the grid makes the system more prone to grid disturbances. The consequences of grid disturbances, such as a rotor overcurrent, stator overcurrent, electromagnetic torque oscillations, and direct current (DC) link overvoltage, are the predominant considerations that affect the rotor circuit, stator circuit, mechanical components, and DC-link capacitor of the DFIG, respectively. These uncertainties affect the operation of the generator and may lead to the generator to be shutdown. In this paper, a novel position for the placement of a passive resistive element (PRE) is illustrated. This position of the PRE placement is compared with all other possible locations for the PRE. The different locations for PRE placement are the stator side, rotor side, across the DC-link capacitor, and between the rotor side converter (RSC) and grid side converter (GSC). This paper aims to determine a cost-effective solution among all possible locations of the PRE placement. The novel position of the PRE, ie, between the RSC and GSC, is the best position among the other possible locations of the PRE, when the performance, cost, and loss are taken into consideration. The effectiveness of the PRE is further compared with the resistive-type superconducting fault current limiter (R-SFCL). The PRE performs better and has a lower cost than the R-SFCL.

“…Due to the increased demand of electricity nowadays, the world is moving towards the use of renewable energy sources because of high efficiency, resource availability, cost competitiveness and environmental adequateness. In this respect, recent researches have been developed towards the improvement of renewable energy technology [1][2][3]. In fact, for an AC collection grid, each wind energy conversion system (WECS) on a WPP includes: a windturbine plus mechanical parts (e.g.…”

“…The FRT is the capability of WECS to stay connected in short periods of fault conditions. This term can also be used to explain the ability of a wind farm to participate to the voltage stability during grid faults [1]. A WPP generally consists of large number of WECS interconnected together either in series, radial, or series-parallel, and injected to a main bus.…”

An improved topology with a fault ride through (FRT) capability when subjected to a DC-link fault-based wind power plant (WPP) employing a Vienna active rectifier-I is proposed in this paper. The proposed system is capable of mitigating fault occurring on the DC-link side using the PWM-controller technique implemented on the Vienna active rectifier. FRT capability analysis is conducted in this paper, simulation results demonstrate the suitability of the control strategy. Actually, use of proposed wind energy conversion unit (WECU) topology has led to the improvement of system stability by maintaining constant output voltage. Furthermore, the WECU integrating Vienna active rectifier-I is also proven as a feasible technology that can be employed in a large-scale WPP or renewable power generations to realize technical and economical efficient grids integration with high voltage direct current (HVDC) transmission systems.
