In this paper, we give the main focus on the proliferation of non-linear loads in power systems, the mitigation of harmonics has become a critical concern to ensure stable and efficient operation. This study presents an analysis of an advanced control active filter (ACAF) designed for harmonic reduction under varying load conditions. The ACAF is a sophisticated solution that employs advanced control algorithms to effectively suppress harmonics and maintain power quality. The research investigates the performance of the ACAF under varying load conditions, which represent real-world scenarios where power consumption fluctuates. A comprehensive analysis is conducted to evaluate the filter's ability to adapt and maintain harmonic suppression efficiency across different load profiles. The study considers various load scenarios, including steady-state operation, transient load changes, and dynamic load fluctuations. The findings of this research contribute to the understanding of advanced control active filters in practical power systems with non-linear loads and varying operating conditions. The analysis provides valuable insights into the design, optimization, and implementation of ACAFs for harmonic mitigation, ultimately improving power quality and system reliability in modern electrical networks. A classified list of 38 publications on this topic is also given for the quick reference.

This paper proposes the application of a combined adaptive controller for the current control loop of a Shunt Active Power Filter (Shunt APF). The proposed approach uses a Variable Structure Controller (VS) together with a Robust Model Reference Adaptive Controller (RMRAC), leading to a VS-RMRAC algorithm. The control law u = θ T ω is comprised by two set of parameters. One set is related with the RMRAC while the other part is related with the VS controller. The VS parameters are used to improve the transient response, and its effect increases when the estimation error increases. The VS-RMRAC is experimentally tested and compared with a Dead Beat current controller in a three-phase four-wire Shunt APF.

“…An example of controller that presents a large number of recursive equations is the RMRAC controller. The main advantages of this controller are its stability under parametric variation and robustness with respect to the unmodeled dynamics [5]. In [6]- [9] this control technique was applied, but in this works, the RMRAC controller was discretized using Z Transform.…”

This paper presents a comparative study of performance between the Z Transform and the Delta Transform applied to a Robust Model Reference Adaptive Controller (RMRAC). To show the differences between the two discretization techniques, the design of a controller applied to an Uninterruptible Power Supply (UPS) is performed. The simulation results are obtained in a scenario where the controller is implemented in a 16-bit fixed-point arithmetic with a sampling frequency of 6kHz. It is observed that the RMRAC controller in discrete-time via Delta Transform presents better performance with fixed-point arithmetic implementation when compared to the Z Transform.
