This state-of-the-art safety standard classifies energy sources, prescribes safeguards against those energy sources, and provides guidance on the application of, and requirements for those safeguards. As a result, several key privacy concerns need to be addressed, including those outlined by the Cyber Security Working Group of the U.S. National Institute of Standards and Technology (NIST). This is extremely important, since the consequences of an attack are directly proportional to the length of time the service is disrupted. padding: 0 !important; if (hitObject) { Information security frameworks for electric power utilities have also been developed by the International Council on Large Electric Systems (CIGRE). We should expect this standard to be used extensively for smart-grid equipment. robust advanced power generation portfolio. 'developer_id.dNDMyYj': true, With increased benefit, however, has come increased risk. */ This strong interdependence means that an action in one part of an infrastructure network can rapidly create global effects by cascading throughout the same network and even into other networks. A smart grid is an electrical grid which includes a variety of operation and energy measures including: . This network represents an -enormous investment, including more than 15,000 generators in 10,000 power plants and hundreds of thousands of miles of transmission and distribution lines. As identified from the risk assessment, safe operating methods define a process that aims to develop and implement workplace-specific safety systems for work, equipment . 1320, Spring 2010. Cybersecurity and interoperability are two of the key challenges of the smart grid transformation. The end vision of the smart grid consists of a highly developed electrical platform that engages consumers, enhances efficiency, ensures reliability, and enables integration of renewable energy and electric transportation. function __gtagTrackerOptout() { In the smart grid (SG), energy management guarantees supply and demand balance while adhering to all system restrictions for cost-effective, dependable, and safe electrical system operation [4-7]. IEEE, vol. The Smart Power System is available in two sizes: SPS-600 (600W . } })(); Reduced operations and management costs for utilities, and ultimately lower power costs for consumers. } if ('undefined' === typeof gaOptout) { 1/10/2023 - 3/11/2023extensioncanvas.ucsd.eduYou will have access to your course materials on the published start date OR 1 business day after your enrollment is confirmed if you enroll on or after the published start date. hitConverted = mapArgs(hitObject); Advanced metering infrastructure (of which smart meters are a generic name for any utility side device even if it is more capable e.g. var arg, hit = {}; 'eventLabel': arguments[4], Smart Grids can be achieved by implementing efficient transmission & distribution systems, system operations, consumer integration and renewable integration. Virtually every crucial economic and social function depends on the secure and reliable operation of these infrastructures. Their latest technology also allows for remote maintenance of the system, eliminating the need for costly and time-consuming on-site servicing.

While all electrical systems share the same basic . This paper proposes a power-system protection device designed to be integrated in smart environments based on Internet-of-Things technologies. Identity theft threat. Safe operation of a batch reactor requires close monitoring and control of reactant and additive flows to the reactor, of the operating temperature and of the agitation. In order to protect electric infrastructure from the threats outlined above, several layers of security are needed to minimize disruptions to system operations. A 2006 study by the Edison Electric Institute (EEI) calculated that putting power lines underground would cost about US$1 million per mile, compared with US$100,000 per mile for overhead lines, making the idea financially infeasible. hitObject = { } Since the terrorist attacks of 11 September 2001, several steps have been taken and initiatives accomplished to enhance the security and reliability of the nations current electricity infrastructure. Send questions or comments to the Webmaster.

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.

In these higher overvoltage categories (IV and III), the value of the mains transient voltages is higher than it would be expected for general indoor-use Category II AC-mains connected appliances. action = 'timing' === arguments[1].hitType ? if ('pageview' === hitObject.hitType) { The implementation of advanced metering infrastructure (AMI) is widely seen as one of the first steps in the digitization of the electric grids control systems. })(); In most cases, this will be achieved by use of DC storage batteries that invert the electrical energy to AC for local use or for sale back to the electric company. IEC 60950-22, Edition 1.0, 2005-10, Information Technology Equipment Safety- Part 22: Equipment to be Installed Outdoors, International Electrotechnical Commission. f.hitCallback(); Today, security patches often are not supplied to end users, or users are not applying the patches, as they fear they will affect system performance. hitObject = arguments[1]; } 861875, May 2005. Much work remains to be done, however, to create standards that, when implemented, will adequately protect the grid from cyberattacks. __gtagTrackerOptout(); Contact: For more information about this course, please email unexengr@ucsd.edu, Course Number:ECE-40314 An audit of 30 utility companies that received the alert showed that only seven were in full compliance, although all of the audited companies had taken some precautions. This is the reality that needs to be addressed. IEC 62368-1 is the new hazard-based safety engineering standard covering audio/video, information and communication technology equipment. Figure 1. In Compliance is a leading source of news, information, education, and inspiration for electrical and electronics engineering professionals. __gtagTracker('js', new Date()); IEC 62368-1, Edition 1.0, 2010-01, Audio/Video, Information and Communication Technology Equipment Part 1: Safety Requirements, International Electrotechnical Commission. In order to defend against the vulnerabilities described above, several security features need to be incorporated into the development of AMI, along with new privacy laws to protect consumers. Now as part of smart grid and green-power initiatives, you can expect to see such systems in residential locations where anyone might have access. 2) Consumers driven by vengeance and vindictiveness towards other consumers making them figure out ways to shut down their home's power. Regarding recent cyberthreat reports, it is fundamental to separate the hype from the truth. Thus, with smart grid, there is the potential to modernize and advance the architecture of the power systems technology in the 21st century, as the newer technology has already advanced the telecommunications technology. Automatic Metering Infrastructure (AMI) is an approach to integrating electrical consumers based upon the development of open standards. } Additionally, intra-campus communication conductors, such as those used for intra-system communications or status alarms, will also need to be protected like telecommunication conductors in accordance with the local electrical code or practices. They can also alert operators to possible threats before any systems are harmed. Choose Heat or Cool from the mode options. Power-monitoring equipment is listed as examples of Category III equipment, or equipment that will be an integral part of the building wiring. 2nd Conf. A smart power system gives its users intelligible monitoring and maintenance of the power being driven to your security system. Copyright 2023, Institute of Electrical and Electronics Engineers, Inc. By Power system security - Introduction Practically, the power system needs to be secured.We need to protect it from the black out or any internal or external damage.The operation of the power system is set to be normal only when the flow of power and the bus voltages are within the limits even though there is a change in the load or at the generation side. As these separate technologies become merged, much of the safety considerations will have to be merged and reconciled as well, particularly at interfaces.
