![]() ![]() It protects the EV batteries and charging system from the critical voltage sag levels. The FRTC system is designed to improve the voltage quality, and it is achieved through the dynamic voltage restorer. The EV battery pack is modeled with lithium-ion batteries. The charging system is constructed by the three-phase controlled rectifier and the dc–dc converter. This article aims to examine the impacts of voltage disturbance on EV batteries and charging systems, and provides a fault ride-through capability (FRTC) to enhance the voltage quality. However, the voltage quality is one of the significant issues in the distribution grid. The results indicate that the use of the proposed SAT-based approach has reduced DT lifetime to 6.30 years from 7.92 years for the same PEV penetration level.Ī high-quality power supply is required for the proper functioning of the electric vehicle (EV) charging system. The proposed framework provides a more realistic life expectancy for DTs compared with a simplified model in the literature. This paper enhances the existing research through the inclusion of PEV spatial-temporal (SAT) charging activities into the assessment models of DT overload and aging, voltage imbalance, and voltage deviation. ![]() In this work, the residential premises are modeled for supply through a detailed secondary distribution system which is integrated as a part of the EDS. The proposed work develops a probabilistic power flow in order to investigate the impact of the stochastic nature of PEVs, PVs, and conventional load. This study proposes a new framework for evaluating and enhancing voltage quality, distribution transformer (DT) overload and aging, while considering residential prosumer ownership of PEVs. The integration of these resources with accurate stochastic models is expected to affect the assessment of the electrical distribution system (EDS) assets. The effects of climate change have resulted in the increased deployment of plug-in electric vehicles (PEVs), solar photovoltaics (PVs), and energy storage systems penetration levels in the residential sector. ![]()
