Smart grid technology can be viewed as a merging of power systems, information technology, telecommunications, switchgear, and local power generation, along with other fields that were once electrical technologies of separated industries. The main function of a smart grid is to manage power consumption in optimal ways, providing the network with more flexibility in case of emergencies. Investment in a smart grid would nearly pay for itself by reducing stupendous outage costs, a savings of US$49 billion per year, and improving energy efficiency, a savings of US$20.4 billion per year. The days and months that followed required extraordinary efforts from many, including alumni of the University of Minnesotas infrastructure systems engineering program. All rights reserved. The Internet, computer networks, and our digital economy have all increased the demand for reliable and disturbance-free electricity; banking and finance depend on the robustness of electric power, cable, and wireless telecommunications infrastructure. Within the context of smart grids, there are different kinds of supporting technologies, such as smart meters that can help monitor energy consumption and promote more effective distribution.[1].

As these separate technologies become merged, much of the safety considerations will have to be merged and reconciled as well, particularly at interfaces. Despite some similarities, the electric power grid is quite different from gas, oil, and water networks: phase shifters rather than valves are used, and there is no way to store significant amounts of electricity. Since it is imperative that the industry maintain 100% uptime, both the physical security of the AMI system hardware and multiple standard IT security features like encryption and authentication must be provided for. Information technology equipment, on the other hand, is generally utilized in Overvoltage Category II environments, or connected to outlets on branch circuits a safe distance away from the service equipment. If the power ever failed for more than a few hours the SPS could . Conversely, an unintentional island can be created when a segment of the utility grid containing only customer-owned generation and load is isolated from the utility control. For over 30 years more electrical power professionals have used this guide for safe, economical system operation than any other in print. Part of the problem is that the existing control systems, which were originally designed for use with proprietary, stand-alone communication networks, were later connected to the Internet (because of its productivity advantages and lower costs) but without adding the technology needed to make them secure. for (var index = 0; index < disableStrs.length; index++) { window['__gaTracker'] = __gaTracker; var em_track_user = true; However, design engineers are also responsible for ensuring electrical systems are designed with safety in mind.
