93, no. } Also, as the amount of off-theshelf, commercially-available ITE sub-components increases in the charging station, it becomes more infeasible to simply increase the spacings or the quality of insulation. Another key value of a smart power system is the ability to remotely and safely recycle power. } 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). NY, hitObject = { However, design engineers are also responsible for ensuring electrical systems are designed with safety in mind. }; A model representation of a population of the water heater devices for the demand side frequency response is considered. Smart meters will need to be cost-effective, since millions will need to be purchased and installed to replace antiquated analog devices. Cybersecurity and interoperability are two of the key challenges of the smart grid transformation. 14621. , and other security systems often overlook a piece of their system that can shut down the entire system if it isnt properly maintained: battery backup. Since existing control system architectures are not random and therefore response characteristics are reproducible, the strength of potential adversaries is amplified. [3]. The security of cyber and communication networks is fundamental to the reliable operation of the grid. if (em_track_user) { } __gaTracker.remove = noopfn; } } Uninterruptable power. This information allows consumers to be charged variable rates for energy, based upon supply and demand. function __gtagTrackerOptout() { Energy storage systems are utilized for managing the peak power demand of the consumer load prole by discharging power during peak hours. display: inline !important; 2, no. As a core module of the online security analysis system, power system state estimation is a major part of a modern energy management system. In addition, examples of some likely smart-grid applications and the safety considerations that would need to be addressed are discussed. Prior to working at AT&T, Mr. Gies was a Tempest engineer for Honeywell-Signal Analysis Center, where he worked on various secure communications projects for the US Army Communications -Electronics Command. Electric power utilities also typically own and operate at least certain portions of their own telecommunications systems, which often consist of a backbone of fiber optic or microwave links connecting major substations with spurs to smaller sites. , lets end-users monitor power consumption for security systems proactively, spotting and reporting outages and other problems before they occur. 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 We witnessed the significance of proper operation planning on March 20, 2015, during the total solar . 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. Current practice is to apply an upgrade or patch only after SCADA vendors thoroughly test and validate it, and this sometimes causes deployment to be delayed by several months. Deception consists of two possible techniques: dissimulation (hiding the real) and simulation (showing the false). Much work remains to be done, however, to create standards that, when implemented, will adequately protect the grid from cyberattacks. f.hitCallback(); Smart Grid technologies offer a new solution to the problem of monitoring and controlling the grid's transmission System. 'eventAction': 'event_action', It is even more complex and difficult to control it for optimal efficiency and maximum benefit to the ultimate consumers while still allowing all its business components to compete fairly and freely. This paper describes the security risks, security objectives and security research trends in smart grid. hitObject.eventAction = 'page_view'; 1320, Spring 2010. Computing layers that must be considered include: The security features to be employed at each layer include examination, detection, prevention, and encryption. This file is auto-generated */ Data stored at the meter and transmitted over communication networks must also meet standard cybersecurity requirements, including confidentiality, integrity, availability, and nonrepudiation. 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. [CDATA[ */ NFPA 110: Standard for Emergency and Standby Power Systems NFPA 101: Life Safety Code NFPA 70: National Electrical Code, Article 517: Health Care Facilities, Article 700: Emergency Systems, Article 701: Legally Required Standby Systems, Article 702: Optional Standby Systems, and Article 708: Critical Operations Power Systems Links between the power grid and telecommunications systems as well as between electrical power lines and oil, water, and gas pipelines continue to be the lynchpins of energy supply networks. [2] Mr. Edison would not be familiar with nuclear power plants or photovoltaic cells, as these technologies were developed after his death in 1931. With this, we should expect a modular approach in evaluating the safety of these appliances, whereby we evaluate the communication subsystems as we would for communication equipment and information technology equipment (ITE), while the bulk of the appliance is evaluated in accordance with the basic safety standard that normally applies to such appliances. The truth is that, as a nation, we must and absolutely can meet the power needs of a pervasively digital society if the United States wishes to maintain its role as a global economic and political leader. /* ]]> */ This course provides best practices of modern distribution power systems. window.gtag = __gtagTracker; (function () { As these separate technologies become merged, much of the safety considerations will have to be merged and reconciled as well, particularly at interfaces. A smart power system gives its users intelligible monitoring and maintenance of the power being driven to your security system. !window.jQuery && document.write('
