Electric Vehicle Load Estimation at Home and Workplace in Saudi Arabia for Grid Planners and Policy Makers

This study proposes a tailored approach for estimating electric vehicle charging loads in Saudi Arabia using real survey data on driving and commuting behaviors. The methodology analyzes daily mileage, home and workplace arrival/departure times, and trip patterns to develop per-unit EV charging profiles. These profiles are then applied to different scenarios involving Level 1 and Level 2 chargers and residential, commercial, and mixed-use buildings. The results indicate that mixed-use buildings can reduce EV peak loads, with an approximately 50% commercial-to-residential ratio producing the lowest peak demand. The findings provide valuable information for grid planners and policymakers in planning EV charging infrastructure and managing future electricity demand.
