• U.S. assisting Ukraine investigate 23 December cyberattack on power grid

    The United States is helping Ukraine investigate last month’s cyberattack last month which disrupted the country’s power grid and left some 80,000 customers without power. Experts say that the 23 December attack against western Ukraine’s Prykarpattyaoblenergo utility was the first known power outage caused by a cyberattack.

  • Extreme weather increasingly threatening U.S. power grid

    Power outages related to weather take out between $18 billion to $33 billion from the nation’s economy. Analysis of industry data found that these storms are a growing threat to, and the leading cause of outages in, the U.S. electric grid. The past decade saw power outages related to bad weather increase, which means that power companies must find a way address this problem.

  • Global electricity production vulnerable to climate change, water resource decline

    Climate change impacts and associated changes in water resources could lead to reductions in electricity production capacity for more than 60 percent of the power plants worldwide from 2040-2069. A new study calls for a greater focus on adaptation efforts in order to maintain future energy security. Making power plants more efficient and flexible could mitigate much of the decline.

  • Harnessing distributed energy devices to balance the power grid

    The electric grid has to balance power supply and demand nearly in real-time, requiring power plants to be adjusted on a second-by-second basis. This instantaneous balance is made significantly more complex by renewable energy such as wind and solar, which add more uncertainty and variability. A new research project is proposing a unique solution to this growing problem: employing the millions of distributed energy resources that already exist, such as solar panels on rooftops and heating and cooling systems in buildings.

  • Making the power grid more resilient, flexible

    “The biggest and most complex machine ever built by humankind” – this is how one researcher describes the U.S. power grid. A research team has been charged with the formidable task of transforming that big and complex machine from the inside out. Inverters convert DC (direct current) electricity to AC (alternating current) electricity, the kind that forms the basis of today’s power grid. To integrate more inverter-based distributed generation into the grid, the researchers are developing a dynamic distribution system (DDS) that supplements centralized power plants, instead of replacing them.

  • Protecting the U.S. electrical grid from cyberattack

    Across the United States, 3,200 separate organizations own and operate electrical infrastructure. The widely dispersed nature of the nation’s electrical grid and associated control systems has a number of advantages, but since the late 1990s, cost pressures have driven the integration of conventional information technologies into these independent industrial control systems, resulting in a grid which is increasingly vulnerable to cyberattack, either through direct connection to the Internet or via direct interfaces to utility IT systems. DARPA is soliciting proposal for creating automated systems to restore power within seven days or less after a cyberattack on the grid.

  • Concerns over attacks on the U.S. electrical grid increase after Paris attacks

    In the aftermath of the 13 November attacks in Paris, U.S. government agencies involved with grid security and utilities are preparing to thwart a major attack on the U.S. electrical grid. Government agencies and utilities believe an attack or series of attacks on the electrical grid of the United States is imminent — more so in the aftermath of the attacks on Paris. They are carrying out drills and exercises to brace for them.

  • Storing renewable energy underground for a reliable, affordable national grid

    A common criticism of a total transition to renewable energy — wind, water, and solar power — is that the U.S. electrical grid cannot affordably store enough standby electricity to keep the system stable. Researchers propose an underground solution to that problem. The researchers use data from single-state calculations of the number of wind, water, and solar generators potentially needed in each state to show that these installations can theoretically result in a reliable, affordable national grid when the generators are combined with inexpensive storage and “demand response” — a program in which utilities give customers incentives to control times of peak demand.

  • Equatorial regions’ power at risk from stormy space weather

    Stormy space weather sweeping across the equator is threatening vital power grids in regions long considered safe from such events, ground-breaking new research reveals. The researchers found that these equatorial electrical disruptions threaten power grids in Southeast Asia, India, Africa, and South America, where protecting electricity infrastructure from space shocks has not been a priority.

  • U.S. enhances national space-weather preparedness

    Space-weather events are naturally occurring phenomena in the space environment that have the potential to disrupt technologies and systems in space and on Earth. These phenomena can affect satellite and airline operations, communications networks, navigation systems, the electric power grid, and other technologies and infrastructures critical to the daily functioning, economic vitality, and security of the United States. The White House Office of Science and Technology Policy said that that is why the administration the other day released a National Space Weather Strategy and National Space Weather Action Plan, and announced new commitments from the federal and non-federal sectors to enhance national preparedness for space-weather events.

  • Quickly, inexpensively locating short circuits in power grids

    When a high-voltage power line is damaged by wind, ice, or a tree, electricity utilities must quickly find the fault location and repair it to meet the power quality requirements or avoid cascade blackout. In the common practice, they locate the fault by first identifying the section without power through the use of sensors placed at regular intervals along the power line. A technician must then go to that section and visually inspect the line in order to find the fault location. Researchers have come up with a new method, which is faster and less expensive, for precisely determining where the short circuit takes place.

  • Smart grids better able to withstand climate change challenges

    At the end of October 2012, Hurricane Sandy swept across the northeastern United States at speeds of more than 90 mph. Millions of people were left in the dark. In an era of climate change, energy management systems will have to become increasingly robust in order to withstand natural disasters like Sandy – and also floods, wildfires, heat waves, and droughts. The U.S. power supply — with more than 9,200 power plants and nearly half a million kilometers of overhead lines, about a third of a million miles – is already feeling the strain today. Smart Grid technologies have helped to make power grids more resilient to climate change challenges.

  • Innovative ways to protect the smart grid

    The physical infrastructure of the U.S. electric grid is aging, overburdened, and vulnerable to natural hazards. This is not the bad news. The bad news is that efforts to solve these issues have opened the door to new vulnerabilities. New approaches which transform how energy is produced, delivered, and consumed have created increased reliance on complex data flows, interconnected systems, and sophisticated technologies – that is, the new smart grid. With smarter systems, however, come equally smart hackers. To stay one step ahead of cyberattacks, engineers and scientists are exploring innovative new ways to operate and secure the grid, using the tools of game and control theory.

  • 2013 attack on Metcalf, California power grid substation committed by “an insider”: DHS

    A senior DHS official last Wednesday revealed that a 2013 sniper attack on a Metcalf, California energy grid substation – which the top U.S. electrical utility regulator has called “the most significant incident of domestic terrorism involving the grid that has ever occurred” — may have been committed by someone on the inside. The attackers fired more than 100 rounds of .30-caliber rifle ammunition into the radiators of seventeen electricity transformers, which caused the radiators to leak thousands of gallons of oil, which made electronics overheat and shut down.

  • Grid Security Conference focuses on information sharing among stakeholders

    More than 300 industry and federal partners are participating in the North American Electric Reliability Corporation’s (NERC) annual grid security conference, or GridSecCon, in Philadelphia, which opened on Wednesday and ends today. The conference is focusing on key cyber and physical security issues and training for enhancing the security and resiliency of the North American bulk power system. Topics of panel discussions include upgrades to NERC’s E-ISAC, cyber and physical security technology options, the transition to Version 5 of NERC’s critical infrastructure protection standards; and expectations for NERC’s third grid security exercise, GridEx III, which takes place 18-19 November.
