safe operation of a smart power system

Indeed, they have provided much of the high standard of living that the more developed countries enjoy. 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. window['gtag'] = __gtagTracker; Why? The diversity and lack of interoperability among the various communication protocols cause problems for anyone who tries to establish secure communication to and from a substation. 'eventValue': 'event_value', Additionally, the charging station terminal where the user pays for and plugs in his electric vehicle needs to be made safe so that unskilled persons may use the station. var disableStrs = [ The total cost of a stronger transmission system would be about US$82 billion over the next decade. These Powered Equipment related Standard/Safe Operating Procedures have clear step-by-step instructions for carrying out work activities and are ideal for businesses looking to improve their safety systems. Accidents frequently happen at railway crossings due to the lack of quickly operating gate systems, and to fewer safety measures at the railway crossing as well. window._wpemojiSettings = {"baseUrl":"https:\/\/s.w.org\/images\/core\/emoji\/14.0.0\/72x72\/","ext":".png","svgUrl":"https:\/\/s.w.org\/images\/core\/emoji\/14.0.0\/svg\/","svgExt":".svg","source":{"concatemoji":"https:\/\/magazine.ieee-pes.org\/wp-includes\/js\/wp-emoji-release.min.js?ver=6.1.1"}}; They provide safe load control switching to ground for resistive and inductive loads depending on the control voltage. Automotive /* -1) { if (__gtagTrackerIsOptedOut()) { That is, rather than develop a single standard for, say, a new electrical service equipment with intelligence, for a smart meter, it would make sense to continue to use the base product safety standard for meters, but plug-in the additional telecommunications and information technology safety modules. } [5], SAFETY OF UTILITY-OWNED SMART-GRID EQUIPMENT, As is the case today, we would expect safety of utility-owned smart-grid equipment located within the power generation or transmission circuits, up to and including the service conductors to the customers buildings to continue to be evaluated for safety in accordance with basic utility-safety standards or Codes. A smart grid combines the existing electrical infrastructure with digital technologies and advanced applications to provide a much more efficient, reliable and cost effective way to distribute energy. 1320, Spring 2010. In addition to the physical threats to such centers and the communication links that flow in and out of them, one must be concerned about two other factors: the reliability of the operators within the centers and the possibility that insecure code has been added to a program in a center computer. The best of American innovation is yet to come, and the smart grid must be part of our future. Contact: For more information about this course, please email unexengr@ucsd.edu, Course Number:ECE-40314 Moreover, numerous types of communication media and protocols are used in the communication and control of power systems. If we agree to take a modular approach to evaluating the safety of the smart-grid technology equipment, then IEC 62368-1 will be well-suited for providing the plug-in modules for evaluating the safety of the information technology and communication circuitry portion of the smart grid equipment. }; Americans should not accept or learn to cope with increasing blackouts, nor should we rest on the notion that the technical know-how, political will, or money to bring our power grid up to 21st century standards do not exist. 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. Upgrading the control and communication systems for the power grid will present many new security challenges that must be dealt with before extensive deployment and implementation of smart grid technologies can begin. We could reasonably expect to see some form of communication interfaces and information technology in some appliances that traditionally would never have had such interfaces (washer/dryers, refrigerators, etc.). The adjunct to the magazine is the monthly PES eNews Update. To protect control systems, well-established information security practices must also be utilized. Our complete line of power solutions give you the reassurance of knowing that no matter what issues come your way, your equipment will be safe. It also points out known safety issues with localized electric power generation systems that will be more enabled by smart grid technology. NIST, Guidelines for smart grid cyber security, The Smart Grid Interoperability PanelCyber Security Working Group, NISTIR 7628, Gaithersburg, MD, Aug. 2010. function __gtagTrackerOptout() { This paper describes the security risks, security objectives and security research trends in smart grid. var em_no_track_reason = ''; if ('undefined' !== typeof arguments[1].hitType) { function __gtagTracker() { Orders ship within ONE business day and regular shipping is always FREE. A Standard/Safe Operating Procedure (SOP) allows workers to perform their job in a consistently safe manner. (function () { An additional defense mechanism is the use of deception. It provides utilities with the ability to detect problems on their systems and operate them more efficiently. Within less than a year after the August 2007 collapse of the I-35W bridge in Minneapolis, Minnesota, a city of sorts on the south side of the former bridge took shape, complete with a host of heavy-duty equipment pieces, temporary on-site areas for casting and other tasks, and crews constantly at work. The security of cyber and communication networks is fundamental to the reliable operation of the grid. Finally, no matter how many layers of security or how much sophistication is used in defense mechanisms, it is essential that the industry hire qualified people. var exactmetrics_frontend = {"js_events_tracking":"true","download_extensions":"zip,mp3,mpeg,pdf,docx,pptx,xlsx,rar","inbound_paths":"[{\"path\":\"\\\/go\\\/\",\"label\":\"affiliate\"},{\"path\":\"\\\/recommend\\\/\",\"label\":\"affiliate\"}]","home_url":"https:\/\/magazine.ieee-pes.org","hash_tracking":"false","ua":"UA-3983727-10","v4_id":""};/* ]]> */ [3].

In the electric power industry and other critical infrastructures, new ways are being sought to improve network efficiency by eliminating congestion problems without seriously diminishing reliability and security. Multiple layers of safety features are incorporated into the design of the radioisotope power systems (or RPS) used by NASA. Electric terrorism: grid component targets, 19942004 (source: Journal of Energy Security). Initial systems were open-framed basic systems ranging from 5.5kW to 10kW. You can also use the thermostat's app to control the temperature. if ('send' === arguments[0]) { As for security, it must be built in as part of its design, not glued on as afterthought. } Better sampling of usage and understanding demand patterns should allow the electric utilities to lower the use of power-generation plants, possibly saving millions of dollars by not having to build new plants to meet increases in power demand. Smart Substations: substations are included monitoring and control non-critical and critical operational data such as power status, power factor performance, breaker, security, transformer status, etc. Reduced operations and management costs for utilities, and ultimately lower power costs for consumers. Those attackers are normally driven by intellectual challenge and curiosity. dataLayer.push(arguments); hit[gaMap[arg]] = args[arg]; Since smart grids will involve the merger of new and familiar technologies, it would make sense to take a modular approach to safety. switchLogin(); 2023 TSG Security. Power Systems Dr. Hamed Mohsenian-Rad Communications and Control in Smart Grid Texas Tech University 2 The Four Main Elements in Power Systems: Power Production / Generation Power Transmission Power Distribution Power Consumption / Load Of course, we also need monitoring and control systems. From a strategic viewpoint, long-term developments and research issues relating to the defense of cyber and physical interdependent infrastructure networks must also be considered. return null; When an island is created purposely by the controlling utilityto isolate large sections of the utility grid, for exampleit is called an intentional island. The equipment would be located outdoors and be installed in a weatherproof housing. Anthony M. Giacomoni is with the University of Minnesota. The internet took thirteenth place on this list, highways were ranked eleventh, but sitting at the top of the list as the most important engineering achievement of the 20th century was the development of the present electric power grid.
