SUMMARYEnergy distribution systems are becoming increasingly widespread in today's society. One of the elements that are used to monitor and control these systems are SCADA (Supervisory Control and Data Acquisition) systems. In particular, these control systems and their complexities, together with the emerging use of the Internet and wireless technologies, bring new challenges that must be carefully considered. Examples of such challenges are the particular benefits of the integration of those new technologies, and also the effects they may have on the overall SCADA security. The main task of this paper is to provide a framework that shows how the integration of different state-of-the-art technologies in an energy control system, such as wireless sensor networks, mobile ad hoc networks, and the Internet, can bring some interesting benefits, such as status management and anomaly prevention, while maintaining the security of the whole system.

Abstract-A communication infrastructure is an essential part to the success of the emerging smart grid. A scalable and pervasive communication infrastructure is crucial in both construction and operation of a smart grid. In this paper, we present the background and motivation of communication infrastructures in smart grid systems. We also summarize major requirements that smart grid communications must meet. From the experience of several industrial trials on smart grid with communication infrastructures, we expect that the traditional carbon fuel based power plants can cooperate with emerging distributed renewable energy such as wind, solar, etc, to reduce the carbon fuel consumption and consequent green house gas such as carbon dioxide emission. The consumers can minimize their expense on energy by adjusting their intelligent home appliance operations to avoid the peak hours and utilize the renewable energy instead. We further explore the challenges for a communication infrastructure as the part of a complex smart grid system. Since a smart grid system might have over millions of consumers and devices, the demand of its reliability and security is extremely critical. Through a communication infrastructure, a smart grid can improve power reliability and quality to eliminate electricity blackout. Security is a challenging issue since the on-going smart grid systems facing increasing vulnerabilities as more and more automation, remote monitoring/controlling and supervision entities are interconnected.Index Terms-Smart grid, communication infrastructure, intelligent network, interconnected power system, monitoring, sensing, cyber security I. BACKGROUND S MART grid is a term referring to the next generation power grid in which the electricity distribution and management is upgraded by incorporating advanced two-way communications and pervasive computing capabilities for improved control, efficiency, reliability and safety. A smart grid delivers electricity between suppliers and consumers using two-way digital technologies. It controls intelligent appliances at consumers' home or building to save energy, reduce cost and increase reliability, efficiency and transparency [1]. A smart grid is expected to be a modernization of the legacy electricity network. It provides monitoring, protecting and optimizing automatically to operation of the interconnected elements. It covers from traditional central generator and/or emerging renewal distributed generator through transmission network and distribution system to industrial consumer and/or home users with their thermostats, electric vehicles, intelligent appliances [2]. A smart grid is characterized by the bidirectional connection of electricity and information flows to create an automated, widely distributed delivery network. It incorporates the legacy electricity grid the benefits of modern communications to deliver real-time information and enable the near-instantaneous balance of supply and demand management [3]. Many technologies to be adopted by smart grid have alread...

This paper describes successful and cost effective design & implementation of PC-based SCADA training system for the natural gas transmission and distribution industry. The design provides robust and automated environment for centralized control of a geographically scattered process. Microcontroller based data acquisition (DAQ) control units for distributed data processing are designed and serially connected with COM port of the remote terminal units (RTUs) via RS485/232 convertor. The real-time information gathered in RTU from sensors is fed to the master terminal unit (MTU) through a dedicated communication link. Visual Basic (VB) is used to develop Human-Machine Interface (HMI) environment for technicians and operators. The in-house HMI development aimed at reliable, cost effective, user friendly and easy to troubleshoot and update software. PC-based SCADA training system and HMI were developed to meet the training needs of Sui Northern Gas Pipelines Ltd. (SNGPL). The design work supports future updates and provides opportunities of research in rapidly evolving field of industrial automation and control.
