The performance of distribution transformers serving several residential networks with multiple Plug-In Electric Vehicle (PEV) charging activity is studied in this paper. Distribution transformers are the weakest link in distribution systems that could soon be subjected to increasing stresses from PEV charging activity. This could significantly impact the reliability, security, efficiency and economy...
This paper investigates the impacts of Plug-In Electric Vehicle (PEV) charging stations on the performance of three-phase three-leg distribution transformers. PEV charging stations are sizeable nonlinear loads because of their large rating ac-dc power conversion electronics. The resulting current harmonics can cause abnormal operation in transformers such as additional losses, reduced efficiency,...
This paper investigates the impacts of PEV charging on the low voltage distribution system and highlights possible detrimental operational issues such as line and transformer overloading, poor voltage profiles and unacceptable system losses. A 415 V residential network including typical daily load variations is modeled for different PEV penetration levels; 20% (low), 30 % (moderate), 60% (high) and...
