“…Therefore, EMT simulation should be considered when the dynamics of the WPP (at some operation point) clearly depend on such non-linearities. EMT simulations are usually more resource-consuming than frequency domain studies [6]. Fig.…”

“…A complex vector analysis (available in stationary and synchronous reference frames) is suitable to evaluate both positive and negative harmonic sequences [8]. In general, it can be stated that frequency-domain methods have a low computational burden and provide good assessments when the effect of active devices is not significant (e.g., at the transmission point of connection) [6].…”

“…In this case, the WPP components are represented by their linear model, which may include passive components and ideal voltage/current sources. Frequency scan and harmonic power flow methods are included in this category [6]. Focusing on harmonic resonances, their frequencies correspond to the eigenvalues of the WPP circuit admittance matrix.…”

“…On the other hand, important phenomena is associated to non-linearities in the WPP circuit, such as core saturation in transformers [9], [10] (and generators in the case of WPP including type III wind turbines [11]), proximity and skin effects in high voltage transmission cables [12], [13] and PWM switching [6]. Time-domain based electromagnetic transient (EMT) simulation methods are better suited to assess non-linear models [1], [6]. Therefore, EMT simulation should be considered when the dynamics of the WPP (at some operation point) clearly depend on such non-linearities.…”

“…Resonance phenomena arise in the transition between inductive and capacitive behavior, with resonances associated to low frequencies usually being the most problematic [2], [6]. E.g., in no loaded off-shore WPPs, low frequency resonances arises because the interaction between transformers (inductive) and cables (capacitive) [14] .…”

Abstract-This work reviews the state-of-the-art in the field of harmonic resonance problems in Wind Power Plants (WPPs). Firstly, a generic WPP is modeled according to the equivalent circuits of its passive and active components. Main focus is put on modeling active components, i.e. the ones based on power converters. Subsequently, pros and cons of frequency and time domain analysis methods are outlined. The next sections are devoted to mitigation methods implemented in the power electronics converters. From the wind turbine perspective, different techniques to enhance the robustness of the controller are analyzed. Subsequently, the suitability for active damping of harmonics using STATCOM devices is assessed, with focus both on control techniques and power converter technologies.

Computer models designed to assess harmonic levels created by renewable energy sources (RESs) need to reproduce the converter operation effect. However, only a few simplified time‐domain models have been developed to predict harmonics while reducing simulation time, which is one of the main limitations of detailed models. This paper presents a novel time‐domain model, called the harmonic average model (HM), to estimate harmonic currents generated by inverters. The superposition principle is applied to include dead time and switching effects in the average model. In addition, the snubber effect is considered by introducing snubber circuits in the HM. Time‐domain simulations of a type‐IV wind turbine are executed with existing models and then with the HM to evaluate the proposed model. Field measurements in a wind power plant and in a photovoltaic plant are used to validate the HM under different power injection scenarios. The results indicate that the HM follows reference currents while accurately estimating the harmonic spectra. Further, the HM is relatively simple to deploy and reduces computation time. A comparison between the HM results and field measurements suggests that the simulated spectra are an adequate approximation of the measured spectra. These results confirm that the HM can be used by transmission system operators to support the prediction of harmonic currents generated by inverters and to estimate the impact of RESs on voltage quality.
