Energy Grid
An electrical grid is an interconnected network for electricity delivery from producers to consumers. Electrical grids vary in size and can cover whole countries or continents. It consists of:Kaplan, S. M. (2009). Smart Grid. Electrical Power Transmission: Background and Policy Issues. The Capital.Net, Government Series. Pp. 1-42. * power stations: often located near energy and away from heavily populated areas * electrical substations to step voltage up or down * electric power transmission to carry power long distances * electric power distribution to individual customers, where voltage is stepped down again to the required service voltage(s). Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same time). This allows transmission of AC power throughout the area, connecting a large number of electricity generators and consumers and potential ...

Electricity Grid Schematic English
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of ...

Electric Grid Security
Electric grid security in the US refer to the activities that utilities, regulators, and other stakeholders play in securing the national electricity grid. The American electrical grid is going through one of the largest changes in its history, which is the move to smart grid technology. The smart grid allows energy customers and energy providers to more efficiently manage and generate electricity. Similar to other new technologies, the smart grid also introduces new concerns about security. Utility owners and operators (whether investor-owned, municipal, or cooperative) typically are responsible for implementing system improvements with regards to cybersecurity. Executives in the utilities industry are beginning to recognize the business impact of cybersecurity. The electric utility industry in the U.S. leads a number of initiatives to help protect the national electric grid from threats. The industry partners with the federal government, particularly the National Institute of Stan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Energy Management Program
The United States Federal Energy Management Program (FEMP) promotes energy efficiency and the use of renewable energy resources at federal sites, helping agencies save energy, save taxpayer dollars, and demonstrate leadership with responsible, cleaner energy choices, because as the largest energy consumer in the United States, the federal government has both a tremendous opportunity and a clear responsibility to lead by example with smart energy management. Equipment procurement Use FEMP's product recommendations and other useful tips to help you buy the most efficient equipment for your offices and facilities and programs.
