Smart grid

  • GridSmart grid needed to shift electrical system to alternative energy: Expert

    Solar, wind, and other alternative sources are easier on the environment but less predictable than coal, gas, or oil-fired plants, demanding a more sophisticated distribution and delivery system. A more resilient, responsive electrical grid – a smart grid – would adjust electrical loads to energy demands, preventing the shutdowns that leave people without air conditioning just when they need it most. A smart grid is thus a flexible grid – it is an infrastructure which allows shifting load and demand around effectively, ultimately balancing the electrical power and delivery system at lower costs.

  • GridAging grid cannot keep up with growing demand for electricity

    The demand for electricity in the United States increased by around 20 percent from 1999 to 2009, but transmission capacity only increased by around 7 percent in that time. From 2000 to 2004, there were 140 instances of power outages which each affected 50,000 or more consumers. This number increased to 303 from 2005 to 2009. Between 2010 and 2012, there were 226 such outages. The average age of a power plant is 30-years old, and around 75 percent of America’s power lines are 25-years old. Economists estimate that these power outages cost the country more than $70 billion in annual economic loss.

  • GridMaking the U.S. grid sturdier, smarter, and more secure to thwart blackouts

    In August 2003, fifty million customers throughout the northeastern United States and southeastern Canada lost power for up to two days. More than ten years later, the U.S. electric power system continues to be challenged. In the United States, 149 power outages affecting at least 50,000 customers occurred between 2000 and 2004, a number which grew to 349 between 2005 and 2009. In 2012, the prolonged power outages in New York and New Jersey caused by Hurricane Sandy once again demonstrated the system’s vulnerability. A broad, multidisciplinary effort by Georgia Tech researchers aims to revolutionize the delivery of electricity, advance the smart grid, thwart blackouts, integrate renewable energy sources, and secure utilities from cyberattacks.

  • GridSoftware to help plan the smart grid

    Researchers have developed a new software tool called the Energy Zones (EZ) Mapping Tool that will help the thirty-nine states which make up the Eastern Interconnection States’ Planning Council, or EISPC identify geographic areas suitable for the development of clean energy resources, which are renewables, natural gas, coal carbon sequestration, and nuclear. Certain forms of energy storage are also included.

  • Grid securityIndustry insiders: insufficient security controls for smart meters

    False data injection attacks exploit the configuration of power grids by introducing arbitrary errors into state variables while bypassing existing techniques for bad measurement detection; experts say current generation of smart meters are not secure enough against false data injection attacks

  • Smart gridSmart grid: from deployment to applications

    Some 200 million smart meters have been deployed worldwide, forty million of them in North America; a new white paper from Pike Research says that the year 2012 represents a turning point for the sector

  • Smarter powerNew material to improve efficiency of power grids

    Global energy demand is on the rise, as populations continue to grow and industrialization progresses; at the same time, there is a growing awareness and concern about repercussions of increasing rates of carbon dioxide emissions released in the atmosphere; a new nanocomposite material holds the promise of enabling smarter, more reliable, and greener power systems

  • Smart gridSmart outlet to bring flexibility, resiliency to smart grid architecture

    Researchers developed an experimental “smart outlet” that autonomously measures, monitors, and controls electrical loads with no connection to a centralized computer or system; the goal of the smart outlet and similar innovations is to make the power grid more distributed and intelligent, capable of reconfiguring itself as conditions change

  • Smart gridNIST releases smart grid framework update

    An expanded list of standards, new cybersecurity guidance and product testing proposals are among the new elements in an updated roadmap for Smart Grid interoperability released yesterday for public comment by the National Institute of Standards and Technology (NIST)

  • Smart gridSiemens chosen to build Fort Collins's electrical smart grid

    Siemens Energy, Inc. was recently chosen by the city of Fort Collins, Colorado to help build its electrical smart grid infrastructure

  • U.S. releases smart grid cybersecurity strategy

    Last week the U.S. Department of Energy released its strategic framework for its plan to install and secure the nation’s electrical grid system over the next decade; the report outlines a plan to coordinate efforts by the government and the private sector to begin designing and implementing an electrical grid that is capable of withstanding a cyberattack

  • Smart grid U.S., Europe Collaborating on Smart Grid Standards Development

    The other day the U.S. Commerce Department’s National Institute of Standards and Technology (NIST) and the European Union’s (EU) Smart Grid Coordination Group (SG-CG) jointly announced their intention to work together on Smart Grid standards development,

  • CybersecuritySafeguarding the Internet of tomorrow

    The recommendations of a high-level cybersecurity summit held Belfast include developing self-learning, self aware cyber security technologies, protecting smart utility grids, and enhancing the security of mobile networks. The summit concluded that these are among the top research priorities needed to safeguard the Internet of tomorrow

  • Boeing and Siemens join forces to protect smart grid

    In a bid to improve efficiency and security for the Pentagon’s electrical “smart grid,” defense giant Boeing has teamed up with German technology conglomerate Siemens to develop new technologies

  • IBM helps Sensus secure the smart grid

    In a move that could help bolster U.S. smart grids against cyberattacks, Sensus recently announced that it will incorporate IBM’s encryption and key management technologies into its smart grids; the company will use IBM’s cyber security solutions in its FlexNet communications system for electric, gas, and water utility smart grid endpoints including meters and automated distribution devices
