The field of advanced digital signal processing methods is one of the fastest developing scientific and technical disciplines, and is important in the field of Shunt Active Power Filter control methods. Shunt active power filters are highly desirable to minimize losses due to the increase in the number of nonlinear loads (deformed power). Currently, there is rapid development in new adaptive, non-adaptive, and especially hybrid methods of digital signal processing. Nowadays, modern methods of digital signal processing maintain a key role in research and industrial applications. Many of the best practices that have been used to control shunt active power in industrial practice for decades are now being surpassed in favor of new progressive approaches. This systematic research review classifies the importance of using advanced signal processing methods in the field of shunt active power filter control methods and summarizes the extant harmonic extraction methods, from the conventional approach to new progressive methods using genetic algorithms, artificial intelligence, and machine learning. Synchronization techniques are described and compared as well.

Summary The increased penetration level of wind power plants has brought new issues and challenges. One of them is the low‐voltage ride‐through (LVRT). This paper proposes a coordinated control and management strategy to improve the capability of a wind‐energy conversion system (WECS) to fulfill the universal LVRT requirements. Moreover, it aims to exploit the system maximum capability in regard to its protection and to ensure an optimized power management. In fact, under grid fault, the machine‐side converter (MSC) contributes to the DC‐link voltage regulation by storing a percentage of the surplus power in the drive shaft inertia of the WECS. Meanwhile, the grid‐side converter (GSC) injects a portion of active power and reactive power required to support the grid voltage recovery. In this condition, the DC‐link voltage is controlled through batteries by a DC‐DC converter and a braking chopper circuit. Whereas, in normal grid conditions, the DC‐link is regulated via the GSC. The proposal supports the WECS to ride through severe low voltages and protects the WECS from excessive current, overvoltage, the PMSG from overspeed, and extends the batteries' lifespan. Simulation results show the effectiveness and the validity of the proposed coordinated control and management strategy.
