“…An impedance-based representation can be used to identify electrical resonances and analyse the influence of grid and VSC control parameters [9,[15][16][17][18]. That is why, to obtain more accurate results, WT frequency-dependent models such as Norton equivalent sources, [9,[13][14][15][16][17][18][19][20][21][22], should be used in WPP resonance studies. In [16][17][18][19][20][21][22], the detailed expression of the Norton equivalent impedance of grid-connected VSCs is analytically characterised for resonance and stability studies considering typical one- [19][20][21] or two- [16][17][18]22] cascade control loops in synchronous (or dq) reference frame.…”

“…Accordingly, Wang et al [21] study the harmonic stability of an islanded three-converter system and Bayo-Salas et al [22] analyse the interaction of two converters connected at different points of the grid. As mentioned in [19,20], resonance characterisation in systems with a large number of converters, such as WPPs, is complex and requires modelling of converters with simplified and aggregated models.…”

Wind turbine harmonic emissions due to power electronics are a well-known power quality concern in wind power plants (WPPs). This problem may be increased by resonances because they amplify harmonic distortion around resonance frequencies. Hence, the resonance phenomenon is widely analysed in the literature. Resonance studies usually consider wind turbines (WTs) as ideal current sources, which can lead to inaccurate results. The study explores the effect of WT converter control on WPP harmonic response. It contributes expressions of WT equivalent harmonic impedance including current control of the grid side converter. This impedance allows WT converter control to be considered in WPP modelling to analyse its effect on harmonic response and resonances. PSCAD and Matlab/Simulink simulations were performed to validate the analytical expressions and illustrate the usefulness of the work in predicting harmonic distortions at WT terminals in actual WPPs.

“…The energy storage unit could be connected to the submodules (SMs) of MMC with a DC/DC converter or an isolated DC/DC converter [7–9]. Furthermore, batteries connected to SMs of MMC directly with the advantage of simple structure, low energy consumption, and so on [10–14]. Therefore, the BESS could be connected to the power grid through MMC.…”

“…Also for some passive elements the numerical representation is less complicated e.g. the grid impedance can be modelled as a numerical look-up table instead of a high order passive network formed of many elements [14]. In addition to all the above-mentioned reasons, finally the numerical evaluation methods such as the Nyquist plot may be used for stability assessment.…”

Abstract-Some couplings exist between the positive-and negative-sequence impedances of a voltage sourced power converter especially in the low frequency range due to the nonlinearities and low bandwidth control loops like the PLL. In this paper, a new numerical method based on the Harmonic Transfer Function for analysis of the Linear Time Periodic systems is presented, which is able to handle these couplings. In a balanced three-phase system, there is only one coupling term, but in an unbalanced (asymmetrical) system, there are more couplings, and therefore, in order to study the interactions between these couplings a matrix based method should be used. No information about the structure of the converter is needed and elements are modelled as black boxes with known terminal characteristics. The proposed method is applicable for both power quality (harmonic and inter-harmonic emissions) and stability studies, which is verified by simulations in this paper.
