The effect of grid codes in V2G charging equipment

Abstract

This thesis examines how global grid code specifications influence the design and development of Vehicle-to-Grid (V2G) charging equipment. V2G technology enables bidirectional power flow between electric vehicles and the grid, providing services such as frequency regulation and renewable energy integration support. The research addresses challenges arising from diverse regional grid codes that establish technical requirements for power quality, voltage control, frequency response, and communication protocols. Through systematic analysis of specifications across Europe, North America, Australia, Asia, South America, and Africa, the thesis identifies critical regional variations affecting V2G charger design parameters, particularly for high-power systems. The investigation covers compliance rules, testing procedures, and certification requirements manufacturers must navigate. By examining how varying grid codes directly impact V2G charger design, the research offers insights for developing adaptable equipment and strategies for harmonizing requirements, ultimately facilitating widespread deployment of this technology in support of sustainable energy systems.
