DC bus voltage four.four. DC bus voltage four. DC bus voltage From Figure 14, it may be noticed that the DC bus voltage oscillation is clear ahead of From Figure it it can observed that the DC bus voltage oscillation is obvious before From Figure 14,14, can be be noticed that the DC bus voltage oscillation is clear just before using the strategies talked about within this paper, andand it can’t be stabilized at the rated value it can not be stabilized at the rated value employing the methods mentionedthisthis paper, it can not be stabilized in the rated worth applying the tactics pointed out in in paper, and soon after a a time frame. Following working with the techniques described in paper, the oscillation time frame. Just after working with the methods described in this this paper, the oscillation after after a time frame. Following using the tactics mentioned in this paper, the oscillation amplitude of of DC bus voltagesignificantly lowered, which delivers situations for the the amplitude DC bus voltage is is considerably lowered, which gives circumstances for amplitude of DC bus voltage is drastically decreased, which delivers circumstances for the typical operation of of grid-side converter. normal operation grid-side converter. standard operation of grid-side converter.1210 1210 1190DC Bus Voltage/V DC Bus Voltage/V1170 1170 1150 1150 1130 1130 1110Previous handle Preceding control Improved manage Enhanced control3.3 three.3 three.four 3.4 3.five three.five 3.six three.6 T/s T/s three.7 three.7 3.8 3.8 3.9 3.1090 10903.3.four.0 4.Figure 14.

Conclusions This study proposed the control technique to avoid sub-synchronous oscillation acciThis study proposed the manage tactic to prevent sub-synchronous oscillation accident by thinking about a case study of the Hornsea wind power program accidental incident. dent by considering a case study of the Hornsea wind power program accidental incident.Energies 2021, 14,12 of5. Conclusions This study proposed the control technique to avoid sub-synchronous oscillation accident by taking into consideration a case study from the Hornsea wind energy program accidental incident. The paper concluded that: 1. The accident response of a sub-synchronous oscillation event inside the Hornsea wind power technique is mimicked in MATLAB simulation according to the data provided in British offi.
