safe operation of a smart power system

As these separate technologies become merged, much of the safety considerations will have to be merged and reconciled as well, particularly at interfaces. The security of cyber and communication networks is fundamental to the reliable operation of the grid. About Smart Power -. The Smart Grid: An Introduction, prepared for the U.S. Department of Energy by Litos Strategic Communications under contract No. Fully integrated battery. } In addition, examples of some likely smart-grid applications and the safety considerations that would need to be addressed are discussed. arguments[5] : 1, Authored by Robert Cordeiro, Technical Director at TSG Security. S. M. Amin, Energy infrastructure defense systems, Proc. It exponentially increases the cost and difficulty of compromising a system by creating a much stronger defense than the use of any individual component alone, thus reducing the likelihood of an attack. In April 2009, The Wall Street Journal reported that cyber spies had infiltrated the U.S. electric grid and left behind software that could be used to disrupt the system. It is not yet known what the smart-grid killer app is going to be, but like pre-season predictions of who is going to win the Super Bowl or the World Cup, some think that it is going to be plug-in hybrid electric vehicles (PHEVs) and possibly full electric vehicles (EVs). padding: 0 !important; It also points out known safety issues with localized electric power generation systems that will be more enabled by smart grid technology. var len = arguments.length; This system is an intelligent residual current fire monitoring detector. } Plugs into a standard wall socket.

Local power generation systems, such as photovoltaic systems, generators, fuel-cell systems, and the like, for which the smart grid will permit the sale of power back to the utility, involve the following safety concerns: The frequency of the locally-generated power has to be synchronized with that of the main grid. Since existing control system architectures are not random and therefore response characteristics are reproducible, the strength of potential adversaries is amplified. } Energy, telecommunications, transportation, and financial infrastructures are becoming increasingly interconnected, thus posing new challenges for their secure, reliable, and efficient operation. This is extremely important, since the consequences of an attack are directly proportional to the length of time the service is disrupted. The various elements considered by CIGRE include security domains, baseline controls, and security processes. Indeed, they have provided much of the high standard of living that the more developed countries enjoy. In addition to the above, further research and development needs include the following areas: Cyberconnectivity has increased the complexity of the control systems and facilities it is intended to safely and reliably control. }); if (typeof arguments[5] === 'object') { The Smart Power System is available in two sizes: SPS-600 (600W . if ('pageview' === hitObject.hitType) { if (!parameters) { window[disableStrs[index]] = true; Definition: The power system is a network which consists generation, distribution and transmission system.

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. Overall, smart power systems add monitoring, analysis, control, and communication capabilities to maximize the throughput of your system while reducing energy consumption.

Much work remains to be done, however, to create standards that, when implemented, will adequately protect the grid from cyberattacks. 'timingVar': 'name', The devices, in turn, process the information based on consumers learned wishes and power accordingly. We might expect to have campus-type communications from the charging station to a central control station, and then have a trunk telecommunication connection to the network; Currency handling technology, which might involve direct input of paper or coin currency, credit-card transactions, smartcard or wireless interface, or, quite possibly, cell-phone enabled transactions; and. task 4 4.1 investigate (a) safe operation of smart power system (b) operation of standalone and grid connected renewable energy systems 4.2 discuss the features of smart grid network 4.3 determine the importance of power electronics in smart grid and energy storage and analyse how power electronic converters are used in smart grid networks 4.4 The Academy compiled a list of twenty accomplishments that have affected virtually everyone in the world. 7, no.

To operate the electric systems in safe mode, the power system component should be equipped with intelligent controllers. It uses a 32-bit microcontroller to effectively monitor the fire hazards that may occur in the protected electrical circuit due to leakage, temperature, and current overload, and handles the remaining current in real time.

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.

It may be necessary to use surge protection devices, either integral to the equipment, or externally connected to limit transient voltages from Overvoltage Category III and IV to Overvoltage Category II. This may mean putting telecommunication protectorsprimary (voltage) or secondary (power-cross) at each end of a campus-run communication conductor where there exist an exposure to lightning or to accidental contact with electric power conductors. display: inline !important; Additional security needs include rapid containment, restoration, and recovery strategies for times when systems are inevitably compromised. return null; if (em_track_user) { Layered security (or defense in depth) involves strategically combining multiple security technologies at each layer of a computing system in order to reduce the risk of unauthorized access due to the failure of any single security technology. Send questions or comments to the Webmaster. A model representation of a population of the water heater devices for the demand side frequency response is considered. Normally, the customer-owned generation is required to sense the absence of utility-controlled generation and cease energizing the grid. 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. 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. A successful terrorist attempt to disrupt the power delivery system could have adverse effects on national security, the economy, and the lives of every citizen. Tap the up or down arrow to pick the specific temperature. 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). Regarding recent cyberthreat reports, it is fundamental to separate the hype from the truth.
