Motivation
u The role of Electric Vehicle in Smart Grid u Distributed Energy Storage u Moving Power Source / Moving consumer
u Day Time : Workplace u Night Time : House
u Repeatedly happens almost every day u EV provide good environments to test and predict a influence at s
mart grid.
u International Protocols u IEC 15118
u EV charging and discharging protocols u Define protocols between EV and charging operators u Not allowed to attend as power producers
u IEC 61850 u Published technical report

IEC 61850
u Reduced configuration costs from common naming and automatic point configuration and retrieval. – SCL
u Equipment migrations occur with minimal impact on applications.
u Application changes have minimal effect on devices, network or other applications.

EV Charger
u Standalone is u possible to perform required operations without the help of anoth
er device. u Expensive because each charger have all components.
u N-Port u Require the assistance of another device to perform the functions
that the administrator needs. u can be cheaply because it is possible to share some common func
tion u General Functions
u Master : manages all the slaves, and performs role as a gateway for communication with a server
u provide the actual recharge service. However, they are impossible to communicate with a server, directly.
