“…Similarly, authors in [29] validated that the reactive power compensation using the EV chargers is beneficial for the voltage regulation within the charging duration. Authors in [30] concluded that the utilisation of reactive power from the EV charger could provide a great potential for the voltage regulation in the distribution system without loss of EV owner's charging demand. Authors in [31] confirmed the effectiveness of the EV voltage regulation method by estimating steady state in order to figure out the limitation of the control capability.…”

“…When large-scale EVs are being charged simultaneously, various severe phenomena affecting the power system could occur. In [2][3][4][5][6][7][8][9][10], the possible effects on the power system are described, including voltage variation, decrease of load factor, increase of power losses, increase of demand power, etc. If compensation devices are used to mitigate these negative effects, additional costs would be incurred.…”

-With the current global need for eco-friendly energies, the large scale use of Electric Vehicles (EVs) is predicted. However, the need to frequently charge EVs to an electrical power system involves risks such as rapid increase of demand power. Therefore, in this paper, we propose a practical smart EV charging scheme considering a Time-of-Use (ToU) price to prevent the rapid increase of demand power and provide load leveling function. For a more practical analysis, we conduct simulations based on the actual distribution system and driving patterns in the Republic of Korea. Results show that the proposed method provides a proper load leveling function while preventing a rapid increase of demand power of the system.

The electrification of transportation has become a sustainable solution to the global economic and environmental challenges associated with the fossil fuel-dependent transportation. Substantial electric vehicle (EV) integration has resulted in the recent past owing to the distinct advantages and various incentives provided by governments. It can be expected that EV penetration will further accelerate along with technological advancements. This strategic shift of primary source of transportation energy from oil pipelines to power grids will inevitably bring numerous challenges to power grids around the world. The potential impacts of EV integration on power grids are yet to be discovered. This research concentrated on modelling the EV charging load, evaluating its impact on power system stability and identifying remedies. Further, two computationally efficient indexes were developed to identify voltage stability and oscillatory stability prudent charging solutions. A comprehensive EV charging infrastructure planning strategy was also developed. This research investigated the probable grid impacts associated with EV charging by comprehensively reviewing the available literature. Even though there were number of system studies on wide variety of grid impacts, scant attention has been paid to impact of EV charging on system stability. Electrification of transportation brings significant load integration to the grid. Hence, it is important to understand the EV charging impact on power system stability.
