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. return hit; In 1990, the U.S. Office of Technology Assessment (OTA) issued a detailed report, Physical Vulnerability of the Electric System to Natural Disasters and Sabotage. A model representation of a population of battery energy storage system (BESS)-based DERs such as smart electric vehicles (EVs) charging, large-scale BESSs, and residential and non-residential BESSs, are highlighted. Education })(); This standard provides requirements and considerations for enclosure construction, overvoltage category consideration, and pollution degrees (environmental exposure) associated with information technology and communications equipment installed outdoors. if ('send' === arguments[0]) { Possible threats to the electrical grid introduced by the use of AMI include: As more utilities move toward using Internet Protocol (IP)based systems for wide area communications and as the trend of using standardized protocols continues throughout the industry, maintaining the security of such devices will be critical. } Mr. Gies has become a leading subject matter expert for his company in the field of global product safety compliance, working primarily with Alcatel-Lucents wireless base station equipment. 'eventCategory': arguments[2], 'ga-disable-UA-3983727-10', The devices, in turn, process the information based on consumers learned wishes and power accordingly. The trend of connecting electrical control systems to the Internet exposes all layers of a system to possible attack. John Woltman, president of Smart Power Systems, says the company's generators "will uniquely provide trucks J1939-compatible communication plus advanced diagnostic capabilities." Connect the power system to 220v mains power using the supplied cord. window.dataLayer = window.dataLayer || []; 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. Educating stakeholders and colleagues about the cyber and physical interdependencies has often been difficult, as those who are distinguished members of the community and understand power systems well but are less aware of their cybervulnerabilities routinely minimize the importance of these noveland persistentthreats. __gaTracker.create = newtracker; It provides utilities with the ability to detect problems on their systems and operate them more efficiently. } As plug-in electric vehicles replace gasoline-only burning vehicles on the market, parking lots will need to be equipped with outdoor charging stations. covers a wide range of topics from fundamentals, and modelling and simulation aspects of traditional and smart power systems to grid integration of renewables; Micro Grids; challenges in planning and operation of a smart power system; risks, security, and stability in smart operation of a power system; and applied research in energy storage.
