Lightning-Induced Overvoltages Transmitted Over Distribution Transformer With MV Spark-Gap Operation—Part II: Mitigation Using LV Surge Arrester

Nehmdoh A. Sabiha, +1 more
- 29 Mar 2010 - 
TL;DR: In this article, the authors investigated the impact of feeder numbers, lengths, types, and loads on the lightning-induced overvoltage reached at the service entrance point of the distribution transformers.
Journal ArticleDOI

Travel Activity Based Stochastic Modelling of Load and Charging State of Electric Vehicles

Muhammad Naveed Iqbal, +6 more
- 02 Feb 2021 - 
TL;DR: A probabilistic approach capable of estimating the time-dependent charging and harmonic currents for the future EV load is presented, based on the detailed travel activities of the existing car owners reported in the travel survey.
Journal ArticleDOI

Enhancing hosting capacity of intermittent wind turbine systems using bi-level optimisation considering OLTC and electric vehicle charging stations

Abdelfatah Ali, +2 more
- 01 Dec 2020 - 
TL;DR: The proposed approach can efficiently enhance/increase the hosting capacity of Wtss in distribution systems, thanks to the consideration of OLTC, reactive power support of WTSs and EVs, and the charging/discharging power of electric vehicles.
Journal ArticleDOI

Customer Interruption Cost in Smart Grids

Amir Safdarian, +3 more
- 01 Mar 2014 - 
TL;DR: In this paper, the impact on the amount of CIC of active customers' flexible demand realized by smart grid technologies is analyzed in the context of residential electricity use in Kainuu, Finland.

Covered-Conductor Overhead Distribution Line Modeling and Experimental Verification for Determining its Line Characteristics

G.M. Hashmi, +1 more
TL;DR: In this paper, the frequency-dependent distributed transmission line (TL) parameters, wave propagation characteristics, and characteristic impedance are calculated and compared with those obtained from the time domain reflectometry (TDR) measurements to validate the theoretical model of the CC line.
