“…Notwithstanding the acknowledgment that this mitigation solution is widely used on wind farms, emphasis is given to the fact that these devices can cause a number of harmful effects to the plant [14]. In this context, highlighted herein are the problems associated with new resonances at other harmonic frequencies, which may lead to increased distortions that propagate to the connecting network [12].…”

“…The first solution is related to the design of the whole plant to avoid resonances at typical harmonic frequencies. In fact, through intelligent system design, harmonic issues can be effectively suppressed by employing special equipment and adjusting the control of converter bridges to avoid high levels of distortions [12]. Alternatively, aiming at mitigating the disturbances of an existing wind power plant, harmonic filtering strategies are widely employed, which may be composed of active or passive-based components [13].…”

“…The active filter is an effective solution for mitigating voltages or currents harmonic distortions. Moreover, due to the increase in new converter technologies applied to the wind turbines, this strategy can be implemented directly to the converter control, reducing the need for external devices [12]. However, even though there exist benefits linked to this technology, its application may result in higher losses when compared to the classical passivebased filter [13].…”

“…In this context, emphasis is placed on the fact that this strategy can cause resonances at other frequencies. It may also impact on harmonic levels by neglecting those issues in studies prior to the connection of the filter [12].…”

Wind farms are power generation complexes with nonlinear characteristics. It is well-known that such facilities are potential sources of harmonic current injection upon the network. In this sense, in cases where limits established by the regulatory agencies are exceeded, filtering strategies must be provided. Under these circumstances, passive filters are a widely employed solution for bringing harmonic distortion levels to within standard limits. However, it is recognized that the connection of passive filters can influence the characteristics of the system, causing resonances and even the intensification of harmonic distortions at the connection point between the wind farm and the external network. Therefore, this paper aims at evaluating the impacts of tuned harmonic filters on grid resonance characteristics and harmonic distortion levels from a wind farm. In this way, based on measurements of currents from an existing Brazilian wind power plant, computational studies are performed in accordance with the guidelines given by Brazilian regulations.

“…There are numerous publications found in the literature specifying the problems caused by the appearance of harmonics in voltage and current, such as, for example, excessive heating, degradation of components, faults in protection and measurement equipment or inefficiencies in the transmission of energy [5][6][7][8]. All of the above can be summed up in an abnormal microgrid operation and low energy efficiency.…”

New-generation power networks, such as microgrids, are being affected by the proliferationof nonlinear electronic systems, resulting in harmonic disturbances both in voltage and current thataffect the symmetry of the system. This paper presents a method based on the application of geometricalgebra (GA) to the resolution of power flow in nonsinusoidal single-phase electrical systems for thecorrect determination of its components to achieve passive compensation of true quadrature current.It is demonstrated that traditional techniques based on the concepts of Budeanu, Fryze or IEEE1459fail to determine the interaction between voltage and current and therefore, are not suitable for beingused as a basis for the compensation of nonactive power components. An example is included thatdemonstrates the superiority of GA method and is compared to previous work where GA approachesand traditional methods have also been used.
