“…Phase conductors and shielding cables are modeled based on tower data [26], [38]- [41]. A brief outline of the EMTP-ATP model used purposely for this paper is presented in the form of a model consisting of several components [42]- [45]: i) generator, ii) phase conductors of transmission lines and shielding cables including line termination and power frequency voltage, iii) transmission line tower, iv) tower grounding impedance, v) string insulator (i.e. arcing horn) flashover characteristics, and vi) lightning current and lightning line impedance.…”

<span lang="EN-US">The number of lightning stroke on the tower of the 150 kV Koto Panjang-Payakumbuh transmission line located the rocky area has been observed. The high value of tower footing resistance indicates the occurrence of the back-flashover in the transmission line at intensity of 74%. The back-flashover occurrence is dominantly triggered by the tower footing resistance value. Also, the rate of back-flashover has an effect on the value of the tower footing resistance by considering the number of electrode installations. A design is proposed for the grounding system of the tower footings in order to reduce the rate of back-flashover. The results presenting in numerical simulation indicates that it works properly after adding 4 electrodes. That is to say, installing 4 electrodes in each tower has successfully decreased the tower footing resistance value, back-flashovers rate 80% and 90-95% of present value respectively. The insulator voltage can be reduced to less than half of the present voltages as much as 30-50%. In more detail, in tower 77, the value of the tower footing resistance drops to 2.84 Ω, the flashover rate drops to 0.57/100 km/year and the insulator voltage drops to 0.99 MV when a disturbance occurs.</span>

“…The MC‐based analysis has been done for the outage of the 230 kV transmission lines. The probabilistic approach based on the MC method has been implemented to evaluate the shielding failure flashover rate and back flashover rate of 230 kV overhead lines 26 .

Summary The assimilation of wind energy into the conventional grid brings several considerable challenges when uncertainties are considered. The uncertainties, including the occurrence of three‐phase fault and lightning fault, are considered to analyze the reliability and performance of the wind energy system. So, a study is a prerequisite for the power system, including wind farm (WF), voltage source converter (VSC), and lightning voltage and current phenomena. Therefore, the present work deals with the generation of lightning envelopes of impulse voltage and current and rectangular pulse current by considering the realistic equivalent circuit. The generated impulse voltage acting as a lightning fault is then implemented on the 3‐phase terminals of grid‐connected Doubly Fed Induction Generator (DFIG) based Wind Integrated Power System (WIPS), which includes six wind turbines (WT) of 1.5 MW each and 120 kV, 60 Hz grid. A 3‐phase short circuit fault is applied further to compare the output responses of the DFIG‐based WIPS. The system's behavior under both faults is observed by determining the controller gain values. The gains, including proportional (kp) and integral (ki) of a sixth‐order transfer function for Wind Turbine Generator (WTG), have been determined by using particle swarm optimization (PSO) algorithm. A reliability assessment of VSC considering DC voltage is done using the Monte‐Carlo (MC) method, considering the lightning impulse voltage (LIV) as a major cause of converter failure. It is found that the DFIG‐based WIPS achieves considerable responses under both types of faults by obtaining the optimal controller values. It has been also observed that the reduction in the number of failures that occurred in VSC during the lightning strike improves the system's reliability.
