Evaluation of the Transient Overvoltages of HVDC Transmission Lines Caused by Lightning Strikes
Energies, 2022 High-voltage direct-current (HVDC) transmission systems are considered an outstanding solution due to high electrical losses emerging from long-distance transmission. However, HVDC transmission lines (TLs) are vulnerable to lightning strikes.

Lightning Overvoltages in Electrical Power System of a Power Plant
2019 20th International Scientific Conference on Electric Power Engineering (EPE), 2019This paper analyzes lightning overvoltage spikes in an internal network of a large power plant. The cases considered are direct stroke to the phase conductor of the connected power transmission line and back flashover resulting from the lightning stroke to the transmission tower or shield wire.

Lightning Overvoltages in Low-Voltage Circuit for Various Lightning Striking Points
IEEE Transactions on Power Delivery, 2010Lightning overvoltages in low-voltage circuits in houses originating from a distribution line or an antenna have been actively studied. However, the mechanism by which damage is caused to home appliances due to a lightning strike to the ground near the house is still unclear.

Analyzing the Effect of Lightning Channel Impedance on the Lightning Overvoltages in Wind Turbines
IEEE Transactions on Industry Applications, 2023Lightning is a natural phenomenon that can cause serious damage to power systems including wind farms. Wind Turbines (WTs) are tall structures and are often installed in areas with high lightning activity levels which makes them exposed to direct strikes.

Evaluation of Lightning Overvoltages for Overhead Transmission Lines Using Unscented Transform
IEEE Transactions on Power Delivery, 2023The Monte Carlo method (MCM) is the most widely used statistical approach to evaluate the lightning performance (LP) of overhead transmission lines (OTLs). However, the MCM has a very high computational burden, making LP studies time consuming.
