ABSTRACT

Communication has always played a critical role in the real-time operation of the power system. Communication between Distribution substation and generation site and consumers can be possible through the point to point and point to multipoint signal transferring across the grid via wireless communication device. Communication network architecture for smart grid is based on broadband wireless communication technology such as 3G, Long term evolution (LTE), L TE-Advanced etc. These are the signals delivered the detailed information of ut ....etc
