“…In reference [15], Kumar and Chatterjee used the artificial bee colony algorithm to solve the maximum power point tracking problem by considering rotor speed as an optimization problem to improve system robustness. In addition, the combination use of supercapacitor energy storage components and passive series dynamic resistors can effectively control rotor overcurrent and overvoltage and suppress fluctuations in DC bus voltage [16]. A virtual capacitor control strategy is introduced to reduce the impact of line impedance by compensating for the output angle deviation of the PLL and improves the stability of DFIG [17].…”

For weak grid scenario with high new energy proportion, large fluctuations of load are prone to cause low-voltage ride through. Moreover, stator transient magnetic flux will cause overvoltage and overcurrent problems in the rotor of doubly fed induction generator. Based on model predictive control, a control strategy for transient flux linkage and reactive power compensation is proposed. Firstly, regarding the issue of reactive power allocation of grid side converters (GSC) and rotor side converters (RSC), an allocation strategy is derived under minimizing winding energy loss on case of low-voltage ride through, enabling the wind energy conversion system to provide reactive power support during grid voltage recovery process. Meanwhile, an improved mixed second- and third-order generalized integrator (MSTOGI) phase-locked loop (PLL) is used to extract the positive and negative sequence components of the power grid voltage, further for RSC control. Secondly, in response to power grid faults, considering the influence of stator DC transient flux and negative sequence flux components on rotor current, by injecting rotor transient compensation current and stator flux feedforward compensation into RSC, the rotor impulse voltage and loop current are reduced. Moreover, combined with model predictive control algorithm, a control strategy of rotor current is designed. Finally, a simulation platform is built to validate the effectiveness of the proposed method based on comparing with several traditional vector control low-voltage ride through methods.

“…Fault current limiters (FCL) such as series dynamic braking resistors (SDBR) [7], superconducting fault current limiters (SFCL) [8] and switching fault current limiters (STFCL) [9] are other alternative hardware FRT enhancement mechanisms because they prevent disconnection of back-to-back converters. In addition, storage devices such as batteries [10], supercapacitors [11], flywheel energy storage [12], and combined methods using Crowbar and SDBR with superconducting magnetic energy storage (SMES) [13] have been used to enhance the active power of the FRT capable network. Thermal runaway with high penetration and overcharging issues are some of the disadvantages of memory-based FRT technologies.…”

Fault Ride through (FRT) capability is one of the critical needs mandated as per new grid regulations to accept large wind energy penetration into grid. In this paper, a hybrid approach has been proposed to improve the FRT of the grid-connected Doubly Fed Induction Generator fed wind energy conversion (DFIG-WEC) system using fuzzy approach. The proposed method has been designed by integrating the rotor side series dynamic braking resistor (RSDBR), the DC-link braking chopper (DCBC) and the rotor end parallel resistor crowbar (REPRC) topologies for limiting the peak values of the fault rotor current, stator current, and dc-link voltage, to protect the rotor-side converter, also reduce torque fluctuations, avoid frequent use of crowbar short-circuit, improve rotor-side converter operation time and the FRT capability. This research article also presents various fault overcurrent scenarios (symmetrical and asymmetrical) and provides protection analysis, including switching methods, coordination with different topologies, and resistance value calculations. The effectiveness of the proposed technique is verified using a MATLAB simulation mode for a DFIG system driven by a typical 1.5 MW wind turbine. The real-time simulator (RTS)based OPAL-RT4500 effectively verifies the operation of the scheme under various fault conditions.

The article presented here utilizes the particle swarm optimization (PSO) and water cycle algorithm (WCA) based dynamic voltage restorer (DVR) to augment the low voltage ride through (LVRT) performance of a hybrid renewable energy system (HRES). Moreover, FACT equipment like the dynamic voltage restorer (DVR) is deployed to boost the quick responsiveness of compensation and good transient performance of HRES. Due to numerous disturbances brought on by WECS' nonlinearity, the best tuning of a PI controller for DVR control is investigated to match the LVRT requirement of the HRES. The design incorporates a battery energy storage system (BESS) that is connected over the DC terminals of the DVR to improve the compensating capabilities by regulating the D-Q axis voltage signal to control the voltage source converter gate signals. In comparison to DVR alone, the suggested technique increases the DC-link voltage and PCC voltage by 44% and 4.6 %, respectively. MATLAB simulation results show that the BESS-enabled PSO DVR performs better in all respect for the compensation of voltage sag and makes the system self-LVRT capable.
