Reduction of Wind Power Curtailment by VSC‐HVDC System Considering LVRT Operation

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
Compared to the system without the VSC‐HVDC system, the fluctuation of VWT (wind‐side PCC bus voltage) in Fig. 9 is reduced when a 300 MVA VSC‐HVDC system is installed. In addition, the smallest deviation of VWT is observed with a 600 MVA VSC‐HVDC system.

Energy Stress of Surge Arresters Due to Temporary Overvoltages

, 2011
The paper presents a method for selecting the rated voltage of a metal oxide surge arresters (MOSA) based on the calculation of energy stresses. The electrical behaviour of gapless MOSA under temporary overvoltages (TOV) is important when selecting the rated voltage of MOSA.
