Recently, diverse activities and initiatives for upgrading the existing power system to the modern energy network have led to discovering a significant requirement for a great revolution in the structure, design, and development of a communications infrastructure with the aim of creating effective interoperability among the controllable systems. In the meantime, the increasing penetration of an array of information technologies and controllable devices together suggests that the communications networks enact critical roles in the electric power infrastructure. Indeed, reconfiguration of the current structure of the multi-carrier energy networks by incorporating the advanced communication protocols is one of the essential steps in the grid modernization process. Therefore, this chapter is developed to introduce the required communication systems for modernizing future energy networks. In this regard, the key role of the communication platforms in coordinating the grid agents is examined considering the effective participation of the various control centers and intelligent devices throughout the modern grid. Also, this chapter investigates how to implement some effective technologies such as the Internet of Things (IoT) in the modern energy grid by adopting capable technologies such as the Internet of Energy while satisfying the modern energy networks’ standards.
