“…Shunt passive filters are widely used to mitigate one or more harmonic frequencies. Their simple construction, reliable operation, and costs have made them one of the most frequently applied solution for power factor correction and harmonic mitigation in industrial applications [20,21]. Another type of passive filter is the series filter.…”

Small-scale wind turbines, which have nominal power capacity less than 50 kW, are generally used in residential and agricultural applications. These turbines are simple-constructed structures, so they are not fully equipped with power quality controllers as bigger ones. Therefore, wind speed and direction affect output voltage and thus battery charging performance directly. It is necessary to determine the generating characteristics of these types of turbines in detail for appropriate output. According to this necessity, in this study, output voltage of an actual horizontal axis wind turbine is analyzed by using the measured data. Harmonic distortion levels for various frequencies are determined from such values. These results are discussed and possible solutions are offered for a quality energy generation.

Basic methods are presented to design a simple filter group and a method of shaping the resultant of the filter group's impedance characteristics (distribution of the characteristics' extremes) and then project equations were transformed into a uniform, common form that addresses issues of the reactive power distribution between component filters. The analysis also takes into account the filters' detuning from the reduced harmonics and quality factors of passive elements. Another important factor of the analysis considered was the power grid equivalent impedance affecting the filtration effectiveness. A criterion for the filter group's filtration effectiveness evaluation was proposed and optimisation was completed for the reactive power distribution between separate filters in the function of the power grid's equivalent inductance.

“…In the literature, the maximization of the PF has received the highest priority as an objective during the design of optimal passive filters [25][26][27], while maximizing the load PF with minimum transmission loss has frequently been taken as a main objective for the design of the compensation elements of passive filters in order to achieve reasonable levels of total harmonic distortion (voltage) (THDV) [28,29]. However, maximizing PF alone may not succeed in minimizing the total harmonic distortion of both voltage and current, although it may work to reduce them.…”

Harmonic issues in power systems are becoming an important topic for industrial customers and power suppliers alike due to their adverse effects in both consumer appliances as well as for utility suppliers. Consumers should seek to reduce harmonic pollution, regardless of voltage or current distortion already present in the network. This article suggests a new method for suppressing distortions by using the non-linearity current index (NLCI) to determine the shunt single-tuned passive filter (STPF) compensator value in non-sinusoidal power systems, with the objective of maintaining the power factor within desired limits. The objective of the proposed method is to minimize the nonlinear current of customer’s loads in the power system at the point of common coupling (PCC). Moreover, the proposed design takes into consideration other practical constraints for the total voltage and individual harmonic distortion limits, ensuring compliance with (Institute of Electrical and Electronics Engineers) IEEE 519-2014 guidelines, maintaining distortions at an acceptable level while also abiding by the capacitor loading constraints established in IEEE 18-2012. The performance of the optimally designed compensator is assessed using well documented IEEE standards based on numerical examples of nonlinear loads taken from previous publications.
