“…Based on CPWM and conventional controllers, the FLC has been proposed for grid‐connected doubly fed induction generator (DFIG) 9 . This scheme has been modified for single‐phase grid connection, 10 but it uses an additional rotor power converter. The reconfiguration of BTB topology as FLC is investigated for fault‐tolerant operation of wind turbines based on DFIG and PMSG 11,12 .…”

SummaryThis paper presents sliding mode pulse‐width modulation (SMPWM) for current‐controlled five‐leg converter (FLC) in wind energy system. The proposed topology substitutes at once two three‐phase converters, classified as back‐to‐back (BTB), by sharing one leg between the permanent magnet synchronous generator (PMSG) and power grid. To overcome the coupling of the two sides, the control of common leg is introduced. SMPWM methodology is designed using system dynamic model and surface decoupling approach to make system tracking desired references. The reference currents are selected to perform control requirements of PMSG wind turbine. The phase currents are controlled simultaneously during normal operation and in the event of unbalanced grid voltages. Different operating conditions are tested under wind variations including a turbulence component. The main objectives are to achieve balanced and sinusoidal currents, as well as smooth active and reactive powers injected into the grid. Simulation results show that FLC can act as BTB converters and demonstrate the effectiveness of the proposed control scheme.

“…On the other hand, very few single-phase to three-phase wind energy systems based on doubly-fed induction generator (DFIG) were discussed in the literature [15]- [17]. A structure of a single-phase grid connected to a three-phase DFIG was discussed in [15], which is illustrated in Fig.…”

This paper presents a three-phase to singlephase six-leg converter for a wind energy conversion system based on Doubly-Fed Induction Generator (DFIG). The converter is composed of six legs and is divided in three parts: the grid-side converter (GSC), which is responsible for power factor and DC-link voltage controls, the stator-side converter (SSC), which guarantees the control of the stator voltage, and the rotor-side converter (RSC), which is responsible for vector control of the generator. One of the converter's legs is shared by gridside and stator-side converters. The main advantages of the proposed configuration compared to other topologies presented in the literature are providing balanced threephase voltages to the DFIG, simple control system and not having any limitation with respect to synchronization between grid and stator voltages and DC-link voltage. The system model, pulse-width modulation (PWM) and control strategies are discussed and simulation and experimental results are presented in order to prove the feasibility of the system.

“…The unified power flow controller is one of the most advanced FACTS devices used in wind applications and consists of two power converters. One converter controls as a STATCOM and the other operates as a static synchronous series compensator to control power flow with the limitation of high cost [99,100]. During grid faults, the reactive power demand can be compensated by an external dynamic STATCOM and an ESS [101], such as hybrid battery-super capacitor energy storage [102].…”

Abstract:This study summarizes an analytical review on the comparison of three-phase static compensator (STATCOM) and active power filter (APF) inverter topologies and their control schemes using industrial standards and advanced high-power configurations. Transformerless and reduced switch count topologies are the leading technologies in power electronics that aim to reduce system cost and offer the additional benefits of small volumetric size, lightweight and compact structure, and high reliability. A detailed comparison of the topologies, control strategies and implementation structures of grid-connected high-power converters is presented. However, reducing the number of power semiconductor devices, sensors, and control circuits requires complex control strategies. This study focuses on different topological devices, namely, passive filters, shunt and hybrid filters, and STATCOMs, which are typically used for power quality improvement. Additionally, appropriate control schemes, such as sinusoidal pulse width modulation (SPWM) and space vector PWM techniques, are selected. According to recent developments in shunt APF/STATCOM inverters, simulation and experimental results prove the effectiveness of APF/STATCOM systems for harmonic mitigation based on the defined limit in IEEE-519.
