Hot Topic Q1 - Overview of Electric Vehicle System Architecture
By Vigna K Ramachandaramurthy, Kang Miao Tan, Jia Ying Yong
In the modern age, energy consumers have high expectations for energy supply reliability. Many advanced measures are required to ensure that the power grid is ready for the large integration of Electric Vehicles (EVs). A proper architecture design for an EV charging system is crucial to ensure a reliable power supply for EV demands. Healthy interaction between the EV and power system can greatly upgrade the reliability and sustainability of the power grid, as well as provide ancillary services to the power grid. This technology is denoted as Vehicle-to-Grid (V2G). In the early development stage of V2G, a small-scale framework shall be easy and efficient enough to stimulate a wider adoption of the technology. This also serves as an educational stage in getting the society ready to accept this new concept. When the technology matures, these small-scale V2G building-blocks can be combined and interact via aggregators for smart grid applications. Literature has demonstrated the flexibility of the EV charger when interacting at various scales of the power grid such as smart home, power distribution grid and microgrid.
