Evaluating the Electrical Network Impact of EV Charging Strategies Used by Operators Across Residential, Workplace, and Public Users

The increasing penetration of Electric Vehicles (EVs) presents significant challenges to the electrical grid, including potential overloads and voltage drops. This study assesses the impact of various EV charging strategies on grid performance within residential, workplace, and public charging environments. The strategies evaluated, either currently in use or readily adaptable by Charge Point Operators (CPOs), include the dispatch of maximum, mean, and intermediate power. The research focuses on key factors such as voltage stability, line loading, and network losses, while also exploring the flexibility that each charging strategy offers in energy service provision. Using comprehensive simulations of the IEEE 69-Bus test system, both with and without EV integration, the study identifies strategies that effectively enhance grid stability and efficiency. The results provide valuable insights for CPOs and grid managers, contributing to the improvement of EV charging infrastructure to ensure a resilient and efficient electrical grid.
