“…An individual inductor is the simplest structure as a filter that is not commonly used for medium and high-power converters due to problems such as voltage reductions in the DC side of the inverter, low dynamic converter efficiency, cost increment, and low power density [20][21][22]. The LCL filter is an attractive solution to overcome the problems mentioned, which improves the harmonic mitigation at lower switching frequency [23]. Nowadays, the most common device used to support the load voltage is a shunt capacitor, which could also improve the reactive power.…”

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.

“…For example, in [2] it was proposed the use of direct neural intelligent techniques to improve performance of a shunt active filters. In other recent studies, it has been proposed the use of differential evolution (DE) algorithms to optimize the parameters of hybrid filters (combining active and passive filters) in order to minimize harmonic pollution [14]. The problem to be solved involves the determination of the most suitable type of passive filter and its parameters to minimize the source RMS current I s in order to get the optimal value I scp .…”

“…Therefore, it is important to investigate how to improve the compensation of the power factor in non-sinusoidal systems in the presence of harmonics. Some investigations have highlighted that algorithms for calculating the parameters of filters have rarely been discussed [13], although in recent years some authors have applied computational optimization methods, including meta-heuristic approaches, for optimizing filter parameters in circuits having harmonic distortion [2,[14][15][16]. More specifically, genetic algorithms have been successfully applied in [17][18][19].…”

Non-linear loads in circuits cause the appearance of harmonic disturbances both in voltage and current. In order to minimize the effects of these disturbances and, therefore, to control the flow of electricity between the source and the load, passive or active filters are often used. Nevertheless, determining the type of filter and the characteristics of their elements is not a trivial task. In fact, the development of algorithms for calculating the parameters of filters is still an open question. This paper analyzes the use of genetic algorithms to maximize the power factor compensation in non-sinusoidal circuits using passive filters, while concepts of geometric algebra theory are used to represent the flow of power in the circuits. According to the results obtained in different case studies, it can be concluded that the genetic algorithm obtains high quality solutions that could be generalized to similar problems of any dimension.

The purpose of this study is to find the optimum sizing parameters of the undamped single tuned filter in the nonsinusoidal system by using a new method called Mixed Integer Distributed Ant Colony Optimization. The inductance and capacitance values of the filter are obtained for each criterion where the power factor is maximized, the losses power in Thevenin's resistor is minimized or the transmission efficiency is maximized complying with the technical and practical constraints based on IEEE Std. 519-2014 and IEEE Std. 18-2012. A detailed study has been performed and discussed where global minimum and maximum are achieved after considering the loads being nonlinear, the value of the filter that would introduce resonance, voltage total harmonic distortion, the consequence of the Thevenin's impedance on the load voltage and the practical values of the capacitor. The obtained optimum value of a single tuned filter is used to explain the system performance by evaluating other functions. The effectiveness of the proposed method is proved by comparison with previous publication and other evolutionary computation techniques which are genetic algorithm and particle swarm optimization.
