Output current spectrum of individual turbines in the operating point described in Tables 1 and 2, being WTG11 the closest to the offshore substation and WTG17 the furthest. Harmonic current amplitude and phase angle are represented for a switching model of the DC wind turbine converter () and for the admittance equivalent model (harmonic model) (). (a) WTG11. (b) WTG12.
