“…The DPC technique used under unfavorable conditions is significantly less present in the literature. For example, the operation under an unbalanced supply voltage is presented in the studies [124][125][126][127], where the extraction of the virtual flux and grid current parameters becomes complicated. On the other hand, authors in [94,119] attempted to extend DPC by employing the p-q extension theory mentioned in [128].…”

There has always been a high expectation that wind generation systems would capture maximum power and integrate properly with the grid. Utilizing a wind generation system with increased management to meet the growing electricity demand is a clever way of accomplishing this. However, wind power generation systems require a sophisticated, unique, and dependable control mechanism in order to achieve stability and efficiency. To improve the operation of the wind energy conversion method, researchers are continually addressing the obstacles that presently exist. Therefore, it is necessary to know which control can improve the whole system’s performance and ensure its successful integration into the network, despite the variable conductions. This article examines wind turbine control system techniques and controller trends related to the permanent magnet synchronous generator. It presents an overview of the most popular control strategies that have been used to control the PMSG wind power conversion system. Among others, we mention nonlinear sliding mode, direct power, backstepping and predictive currents control. First, a description of each control is presented, followed by a simulation performed in the Matlab/Simulink environment to evaluate the performance of each control in terms of reference tracking, response time, stability and the quality of the signal delivered to the network under variable wind conditions. Finally, to get a clear idea of the effect of each control, this work was concluded with a comparative study of the four controls.

“…The controllers are implemented in two different reference frames rotating at fundamental frequency after the decomposition of the inverter ac voltage and current into positive, negative, and homopolar sequence components. The positive and negative sequences decomposition is often used in three-phase, three-leg converters control strategies for load compensation and sinusoidal currents generation under unbalance voltage disturbances [12]- [15], or voltage dips mitigation [16]. The strategy presented in this paper has the ability to decompose and to control into dq dc quantities not only the positive and negative current and voltage sequences but also the homopolar sequence.…”

In this paper, the transient operation of a four-leg inverter equipped with an innovative control strategy under unbalanced load conditions is investigated. The inverter is proposed for transformerless hybrid power system applications, in order to provide simultaneous supply of three-phase and single-phase ac loads with balanced voltage and constant frequency. The four-leg inverter is controlled to ensure balanced voltage by means of a control strategy based on the decomposition of the supply three-phase voltage and current into instantaneous positive, negative, and homopolar sequence components using phasor representation. These three sequences are controlled independently in their own reference frames as dc signals. The implementation derived for the controller design is also described. The transient operation performance of the proposed control strategy has been tested in simulations with an average model and experimentally using a laboratory prototype.Index Terms-Current control, dc-ac power conversion, hybrid power integration, inverters, power quality, symmetrical components, unbalance, voltage control.
