Thus, staff members must be well trained to respond to a wide variety of emergencies since no amount of technology can replace well-trained personnel. As a result, cybersecurity is just as important as physical security, if not more so. Initial systems were open-framed basic systems ranging from 5.5kW to 10kW. 2011. Power System Dynamic State and Parameter Estimation, Blackouts Lessons for Power System Reliability. Smart GridSafe, Secure, Self-Healing | IEEE Power & Energy Magazine He is a member of the Alcatel-Lucent Technical Academy. With diminished transmission and generation capacity and with dramatic increases in interregional bulk power transfers and the diversity of transactions, the electric power grid is being used in ways for which it was not originally designed. Furthermore, since it will be impossible to protect against all threats, smart meters must be able to detect even the most subtle unauthorized changes and precursors to tampering or intrusion. padding: 0 !important; In remote locations, stand-alone systems can be more cost-effective than extending a power line to the electricity grid (the cost of which can range from $15,000 to $50,000 per mile). (a.addEventListener("DOMContentLoaded",n,!1),e.addEventListener("load",n,!1)):(e.attachEvent("onload",n),a.attachEvent("onreadystatechange",function(){"complete"===a.readyState&&t.readyCallback()})),(e=t.source||{}).concatemoji?c(e.concatemoji):e.wpemoji&&e.twemoji&&(c(e.twemoji),c(e.wpemoji)))}(window,document,window._wpemojiSettings); 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. .wp-block-navigation a:where(:not(.wp-element-button)){color: inherit;} The safety aspects of the use of such devices were discussed at a meeting at the IAEA at the end of February. 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. In addition, adversaries often have the potential to initiate attacks from nearly any location in the world. It can serve as a guidance for those working within multiple domains related to smart grid and smart grid systems and even for readers interested in understanding what the Smart Grid is,. The results of a 2007 McAfee survey highlight the pervasiveness of such attacks. } Moreover, the number of threats against computer systems is rapidly increasing due to the increased availability of highly sophisticated hacker tools on the Internet and the decrease in technical knowledge required to use them to cause damage. DE-AC2604NT41817, Subtask 560.01.04. There is reasonable concern that national and international energy and information infrastructures have reached a level of complexity and interconnection that makes them particularly vulnerable to cascading outages, whether initiated by material failure, natural calamities, intentional attack, or human error. The solid line shows the bounding values for DC . } P. H. Corredor and M. E. Ruiz, Against all odds, IEEE Power Energy Mag., vol. 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. if ('pageview' === hitObject.hitType) { . P. McDaniel and S. McLaughlin, Security and privacy challenges in the smart grid, IEEE Security Privacy, vol. Fast switchover. if (! 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. These include the Complex Interactive Networks/Systems Initiative (CIN/SI), a joint program sponsored by the Electric Power Research Institute (EPRI) and the U.S. Department of Defense (DOD); EPRIs Enterprise Information Security (EIS) program; EPRIs post9/11 Infrastructure Security Initiative (ISI); and various North American Electric Reliability Corporation (NERC) initiatives, such as its information sharing and analysis centers (ISACs), public key infrastructure (PKI), and spare equipment database. NY, The proposed system enhances electrical safety by fast disconnection of the power supply in case of fault events like leakage current, electrical arc, overcurrent or overvoltage and has been designed with the goal to be integrated in smart environments . The solar capability offers a valuable safety net. Some of these components are vulnerable to saboteurs with explosives or just high-powered rifles. The report also documented the potential costs of widespread outages, estimating them to be in the range of US$1 to US$5 per kWh of disrupted service, depending on the length of the outage, the types of customers affected, and a variety of other factors. Power-monitoring equipment is listed as examples of Category III equipment, or equipment that will be an integral part of the building wiring. }); The existing power delivery system is vulnerable to both natural disasters and intentional attack. There are no sections of this course currently scheduled. The Safe Operating Area of Power MOSFET is given here: All the maximum voltage and current ratings and power dissipation are conveniently brought together in the safe operating area diagram. When an island is created purposely by the controlling utilityto isolate large sections of the utility grid, for exampleit is called an intentional island. Secure and reliable operation of the electric system is fundamental to national and international economic systems, security, and quality of life. For example, if we have a smart meter with integral information technology and telecommunication interfaces, you could use the international or locally-adopted safety standard for power meters, then use IEC 62368-1 to evaluate the type of personnel that would require access to the smart meter (skilled, instructed, or ordinary), [3] and then determine the level of safeguarding necessary in such areas as isolation from the power equipment, isolation from the telecommunication equipment, construction of the enclosure as a safeguard against accessibility to shock and containment of fire, and so forth. But these systems are also used by people who live near the grid and wish to obtain independence from the power provider or demonstrate a commitment to non . This article is a survey of smart grid literature till 2011 on the enabling technologies for the smart grid. 2) Consumers driven by vengeance and vindictiveness towards other consumers making them figure out ways to shut down their home's power. 3, pp. An additional defense mechanism is the use of deception. This file is auto-generated */ Smart switch applications Smart switches can be used in numerous applications, with motor and LED drivers being among the most common. 4, pp. While some of the operations on the system are automatic, human operators in system control centers ultimately make the decisions and take the actions that control the operations of the system. Due to the gravity of these threats, the Federal Energy Regulatory Commission (FERC) policy statement on the smart grid states that cybersecurity is essential to the operation of the smart grid and that the development of cybersecurity standards is a key priority. } else { } Figure 3. robust advanced power generation portfolio. The digitization of such systems may enable remote attacks to grow rapidly, potentially spanning countries or even continents.
