“…An APF is usually connected to the point of common coupling (PCC) in parallel or series to perform its designed functions; however, shunt APFs are more commonly used because they provide more flexible compensation functions though current-injecting control and require less auxiliary equipment. When a series APF and a shunt APF are connected with a common direct current (DC) link, they can be used simultaneously, known as a unified power quality conditioner (UPQC) [1][2][3][4].In open literature, there are a lot of papers investigating the application of APF to the mitigation of PQ issues, such as the improvement of PCC voltage stability [5,6], compensation of harmonic currents [5][6][7] and unbalance load currents [7,8], injection of active power [8,9], regulation of reactive power [6,9], etc. In order to develop high-performance APFs, it is crucial to improve the switching performance of power converters.…”

Renewable energy (RE)-based power generation systems and modern manufacturing facilities utilize a wide variety of power converters based on high-frequency power electronic devices and complex switching technologies. This has resulted in a noticeable degradation in the power quality (PQ) of power systems. To solve the aforementioned problem, advanced active power filters (APFs) with improved system performance and properly designed switching devices and control algorithms can provide a promising solution because an APF can compensate for voltage sag, harmonic currents, current imbalance, and active and reactive powers individually or simultaneously. This paper demonstrates, for the first time, the detailed design procedure and performance of a digitally controlled 2 kVA three-phase shunt APF system using gallium nitride (GaN) high electron mobility transistors (HEMTs). The designed digital control scheme consists of three type II controllers with a digital signal processor (DSP) as the control core. Using the proposed APF and control algorithms, fast and accurate compensation for harmonics, imbalance, and reactive power is achieved in both simulation and hardware tests, demonstrating the feasibility and effectiveness of the proposed system. Moreover, GaN HEMTs allow the system to achieve up to 97.2% efficiency.

“…However, a chronological survey of active compensation technologies in the literature [8][9][10] shows that attention to those devices during the last decade has risen again, due to the new challenges caused by DG. Indeed, conventional Active Power Filters were primarily designed to compensate harmonics caused by nonlinear load within the client side in a centralized generation system (i.e.…”

“…Indeed, conventional Active Power Filters were primarily designed to compensate harmonics caused by nonlinear load within the client side in a centralized generation system (i.e. under the assumption that the grid is already a stable electrical power source with good quality, where the worst-case scenario is unbalanced phases) [8]. However, with the DG rising to be one of the most actively developed sectors of energy.…”

With an electrical grid shifting toward Distributed Generation (DG), the emerging use of renewable energy resources is continuously creating challenges to maintain an acceptable electrical power quality thought-out the grid; Therefore, in an energy market where loads are becoming more and more sensitive in a distributed generation filled with polluting nonlinear loads, power quality improvement devices such Active Power Filters (APFs) have to evolve to meet the new standards, since theirs conventional control strategies can't properly operate when multiple power quality problems happens at once, even the one using AI based control as it will be proven in this paper. In this paper a neural network based Active Power Filter will be tested in a DG environment where both current and voltage harmonics, along with fast frequency variation occurs, we will see how the PLL can downgrade its performances enormously under such hostile conditions, We propose to solve this problem by replacing the conventional PLL with a nonlinear least square (NLS) frequency estimator, this novel NLS-ADALINE SAPF is immune in high DG penetration environment, as it will be tested and validated experimentally on an Opal-RT OP5600 FPGA based real-time simulator.

Summary In this paper a novel topology of switched capacitor based multilevel inverters is proposed. In this topology, to increase the output voltage levels and to add the voltage boosting capability, several switched capacitor units are cascaded in series. Having voltage boosting capability and generating maximum number of output voltage levels using minimum number of circuit components, is a merit for this topology. To highlight the attributes of the proposed topology, it is compared with other recently proposed multilevel inverters on number of circuit components such as power electronic switches, diodes and capacitors, voltage boosting capability, total standing voltage, cost and efficiency. The comparison results verify the superiority of the proposed topology over other proposed topologies on number of circuit components, and number of output voltage levels. It is also clear that, this topology has lower voltage stress on power electronic switches, which makes it an appropriate solution for industrial applications. Finally, to show the capabilities of the proposed topology, and to verify the accurate operation of the topology, circuit analysis as well as the experimental results are provided.
