Security Communications Network For Interoperable Smart Grid
The ever increasing electric energy demand, together with the complex and nonlinear nature of the electric power
distribution network, have caused serious power network issues in recent years. The promotion of modernized electric
network (smart grid) that integrating control, automation, communication, information, and power technologies to deliver
sustainable energy has been widely recognized. A smart grid system consists of many different subsystems that might have
over millions of consumers and devices, the demand of its reliability is extremely critical. An interoperable communication
network and its security is a key for the success of the emerging smart grid to deliver efficiently quality and reliable energy.
In this paper, some of the key communications and their security challenges for realizing interoperable smart grid are
presented. First, the background of smart grid system is introduced and the interoperability is addressed. Then, smart grid
interoperable reference model (SGIRM) is described, and finally communication network and security measures for
interoperability is presented. The aim of this paper is to offer a guideline of communication network and security
requirements for interoperable smart grid.
