Dynamic Operating Envelope-Based Electric Vehicle Charge Controller for Modern Distribution Systems

The exponential uptake of electric vehicles (EVs) represents a significant advancement toward achieving sustainable transportation goals. However, their integration into low-voltage distribution networks presents significant challenges for power system engineers, primarily due to the increased load demand and variability introduced by widespread EV charging. This paper presents a dynamic operating envelope (DOE)-based EV charging scheme to mitigate voltage violations in low-voltage distribution networks. A real-time voltage-to-load sensitivity methodology is employed to determine the maximum allowable import limit. As DOE is the principled allocation of available system capacity among individual connection points at each time interval, the proposed method is particularly well-suited for modern distribution systems with communication capabilities. A modified IEEE European low-voltage test system is used, in which each EV connection point can exchange data with the distribution transformer. Simulation results demonstrate the effectiveness of the proposed method in alleviating voltage issues while maintaining fairness among EVs.
