“…Current controllers are designed to control positive and negative sequences of the rotor current on the basic of machine models in positive and negative d-q reference frames in order to achieve four targets such as: the balance of stator current, constant output active power, invariant electromagnetic torque for reducing the mechanical stress, and oscillation of the rotor current [4]. In detail, both positive and negative sequence components are used in this scheme.…”

“…The stator voltage's magnitude is determined by the exchange of reactive power between generator and the grid while the phase difference is controlled by active power [4]. Therefore, power balance must be maintained on the grid.…”

“…A voltage drop proportional to current and radial distance to the substations happens when a fault occurs. Due to the remote location of wind farms, the voltage difference may be well out of the limits and this could result in multiple disconnections on the wind farms [4].…”

“…Therefore, a mismatch in power supply and demand on the distribution network could lead to a change in rotational energy stored in the generator. This will cause a decrease in frequency if the power supply is insufficient and an increase in frequency if the power supply is excessive [4].…”

This paper presents a new vector Hysteresis Current Control (HCC), which is applied on a three-phase three-level Voltage Source Inverter (VSI) and eliminate rotor currents harmonics using PI-Fuzzy controller (PI-F). The proposed control technique is used to control the active and reactive power of wind turbines by means of controlling the rotor currents of the Doubly Fed Induction Generator (DFIG) during grid voltage distortion for reduction of current harmonic using PI-F. These control techniques use single or multiple applications of hybrid PI-F with anti-windup and Notch filter to eliminate the second-order harmonic components and negative sequence components. In the newly proposed SFOC-based scheme, PI controllers with Fuzzy, Notch filters and the Sequence Component Controller (SCC) are utilized. The designed system consists of an induction generator with slip ring and power-electronics converters at both rotor and grid sides. The modifications are applied to the Rotor Side Converter (RSC). Simulations in Matlab/Simulink illustrate the enhanced stability of torque, active and reactive powers delivered by DFIG in both the PWM controller (PWM) and HCC schemes. Moreover, comparisons in simulation results, obtained separately from all the presented control structures, are provided to evaluate the effectiveness of the newly proposed scheme.

“…Although the use of variable-speed wind turbines with power electronic interfaces is the current trend, many directly connected induction-generator-based wind turbines are still in operation. All wind turbine technologies, irrespective of type, employed in high-power wind farms, are required by new grid codes in some countries to have a fault ridethrough capability for faults on the transmission system [2]. To deal with this situation, flexible AC transmission system (FACTS) devices (such as a STATCOM) can be used.…”

The substantial increase in new integration of wind power has required changes in grid codes to ensure grid security. Providing low voltage ride through (LVRT) protection helps to sustain the transient conditions without tripping and supports its recovery post-fault. The grid codes for LVRT capability in countries with substantial wind capacity are surveyed in this paper. The challenges that arise, endangering the grid security due to the nonimplementation of these grid codes in the wind turbines (WT) which were preinstalled before the mandatory grid code was established is rarely a topic focused in literature. The LVRT capability requirement as per the wind turbine type classification is elucidated. The challenges due to enhancement and upgradation of technology include financial constraints for additional LVRT fittings, planning and renovation. Discussion and prognosis on the challenges provide direction for investigation and research.
