“…These converter losses can be classified into four subdivisions, including passive output filter losses (AC losses), conduction losses, switching losses of power switches, and DC-side losses. Semiconductor conductive losses due to equivalent resistance and voltage drop in the conducting state and switching losses are due to the improper operation of the switches [9,10].…”

This paper outlines some modifications to conventional active power filters (APFs) to compensate for the non-linearity of the load current. Since the APFs inject the required non-linearity of the load harmonic current to make the current source sinusoidal, a combination of passive power filters (PPFs) and APFs in series connection are more effective rather than individual usages. The proposed control approach based on sliding mode control (SMC) with a suitable sliding surface selection being applied to the proposed hybrid APF to increase the flexibility and reduce the complexity of the controller. An outstanding tracking process based on the reference current in the rotating dq frame is tested and guarantees the rapid convergence exponentially. An extra control loop is provided for DC link voltage regulation to minimize the DC ripples and control the APF three-phase output voltage levels. The presented solution provides an effective and straightforward load voltage support, maintaining an excellent dynamic performance in load changing and current compensation. The experimental results represent the authenticity of the proposed hybrid APF performance through several different tests, implying a feasible control approach for active filtering systems.

“…A DC-link voltage based control has been employed in [12] not only to compensate the DC-link voltage but also to enhance the steady-state performance of the SAPF. Similarly, a multi-objective optimization was proposed in [13] to improve this type of control by best tuning of PI parameters, and finding optimal values of DC capacitors and other parameters of the system. These methods offer a reduction in high-frequency ripple current.…”

This paper introduces an efficient control approach to enhance harmonics mitigation performance of the Shunt Active Power Filter(SAPF). This approach is based on adaptive filters favored by their built-in automatic parameters adaptation capability. The proposed filter, which uses a Variable Leaky Least Mean Square (VLLMS) adaptation, is applied with a modified instantaneous power PQ theory. This enhances its dynamic performance over the use of conventional time-invariant filters, and overcomes its limitations in the presence of non-sinusoidal voltage conditions. The studied SAPF model is simulated in MATLAB/SIMULINK with combinations of non-linear and unbalanced loads. Simulation results indicate a significant improvement in the transient response to less than a quarter of a cycle in its worst case, on top of additional improvements in the steady-state THD value. Moreover, the algorithm's computation efficiency evaluated in an embedded hardware prototype has given a fast execution time of 1.4µs .

“…Some scholars use these meta-heuristic methods to designed the filters in the power system. For example, predator-prey based firefly optimization [15], ant colony optimization [16], particle swarm optimization [17], ant direction hybrid DE [18], genetic algorithms [19], bacterial foraging optimization [20], etc. However, most of these methods are applied to design PPF; a small number of meta-heuristic methods are used to design HAPF.…”

Hybrid active power filter (HAPF) is a novel technique of harmonic filter which combines superiorities of both active and passive filters. However, extracting appropriate parameters of the HAPF, including active filter gain, passive inductive, and capacitive reactance within a constraint space is still a challenging task. To obtain more accurate parameters of HAPF, this paper proposed a new population-based algorithm named ASC-MFO. In ASC-MFO, the swarm is divided into two sub-swarms, i.e., exploitation group and the exploration group. The exploitation group adopts the SFM in the MFO algorithm to enhance the exploitation ability, while the exploration group utilizes the SCM in the SCA algorithm to emphasize exploration. Besides, a personal best flame generation (PFG) strategy and a hybrid exemplar generation (HEG) strategy are developed for the exploitation group and the exploration group to further enhance the exploitation ability and the exploration ability of the two subgroups, respectively. Moreover, an adaptive strategy is proposed to automatically resize the population number of two sub-swarms during the iterative process, which can precisely balance the exploration and exploitation ability between groups in every single generation. The proposed ASC-MFO is applied to design the two most commonly used topologies of the HAPF, where each topology contains four actual cases. Comprehensive experimental results demonstrate that ASC-MFO obtains an excellent performance among those well-established algorithms, especially in the aspect of accuracy and reliability.
