“…Mirhosseini et al [351] discussed control of a large-scale gridconnected PV power plants operating under unbalanced grid voltage sags without the need for phase angle synchronisation, while a dissonant-resonant controller for negative-sequence voltage elimination for a grid-feeding converter is proposed in [352] and Zhang et al [353] discussed a model predictive DPC for DFIG under unbalanced conditions. The modelling and experimental validation of another strategy for DFIG systems under distorted and balanced systems is discussed in [354]. Zarei et al [355] proposed a control scheme to remove the third harmonic component in the output currents of grid-following inverters, under unbalanced grid conditions.…”

Unbalance or asymmetry in the distribution network is a well-known power quality issue. In the modern active distribution system, with the increasing penetration of renewables, this phenomenon becomes more pronounced. In the context of microgrids (MGs), several works have been proposed for the management and mitigation of the unbalance, for both the sharing of unbalanced load and maintaining the voltage quality in the islanded mode and for the control of distributed generators in the grid-connected mode during unbalanced conditions. This study comprehensively reviews, summarises, and classifies the various strategies of the unbalance mitigation techniques for the islanded and grid-connected modes of operation for threephase MGs and presents the possible challenges and avenues for future investigations on the topic.

“…In order to offset the influence of negative-sequence grid voltage, the SGSC is capable of injecting series compensation voltage to balance the stator voltage. The stator flux can also be controlled by the series voltage injection through the SGSC [55][56][57][58]. operation, the SMES circuit is activated to smooth the output power of wind turbines.…”

In recent years, considerable advances were made in wind power generation. The growing penetration of wind power makes it necessary for wind turbines to maintain continuous operation during voltage dips, which is stated as the low-voltage ride-through (LVRT) capability. Doubly fed induction generator (DFIG)-based wind turbines (DFIG-WTs), which are widely used in wind power generation, are sensitive to disturbances from the power grid. Therefore, several kinds of protection circuits and control methods are applied to DFIG-WTs for LVRT capability enhancement. This paper gives a comprehensive review and evaluation of the proposed LVRT solutions used in DFIG-WTs, including external retrofit methods and internal control techniques. In addition, future trends of LVRT solutions are also discussed in this paper.

“…Generally, these converters operate with full power rate only for a short period within a whole day. In most periods, they operate under low power rate conditions, which means that a large amount of potential capacities are wasted [11–14]. Take the PV converter as an example, it only outputs high power during the midday when the sunlight is strong.…”
