Transport sector transformation: integrating electric vehicles in Turkey’s distribution grids

This study investigates the impacts of integrating electrical vehicles to pilot distribution grids in Turkey to quantify technical concerns and solutions for the year 2030. Different charging loads that discern home, workplace and public charging are considered under two different cases; “home-charging-support” and “public-charging-support.” Random variables describing arrival time of electrical vehicles to the charging stations and associated state of charge at arrival time are modeled with a stochastic approach. Dependencies of electrical vehicle integration capacities of the pilot regions are investigated quantitatively based on several key performance indices. The study also analyzes effects on key performance indicators of demand response by electrical vehicle users, defined as smart charging. Key results show that there is sufficient capacity in the four selected Turkish distribution grids to integrate almost 10% electrical vehicles in the vehicle stock by 2030. Based on the results, priority areas are outlined for stakeholders including energy policymakers.
