An electrical grid is an interconnected network for delivering electricity from suppliers to consumers. It consists of generating stations that produce electrical power, high-voltage transmission lines that carry power from distant sources to demand centers, and distribution lines that connect individual customers.
Power stations may be located near a fuel source, at a dam site, or to take advantage of renewable energy sources, and are often located away from heavily populated areas. They are usually quite large to take advantage of the economies of scale. The electric power which is generated is stepped up to a higher voltage at which it connects to the electric power transmission network.
The bulk power transmission network will move the power long distances, sometimes across international boundaries, until it reaches its wholesale customer (usually the company that owns the local electric power distribution network).
On arrival at a substation, the power will be stepped down from a transmission level voltage to a distribution level voltage. As it exits the substation, it enters the distribution wiring. Finally, upon arrival at the service location, the power is stepped down again from the distribution voltage to the required service voltage(s).
National power is defined as the sum of all resources available to a nation in the pursuit of national objectives.
National power stems from various elements, also called instruments or attributes; these may be put into two groups based on their applicability and origin - "national" and "social".
Important facets of geography such as location (geography), climate, topography, and size play major roles in the ability of a nation to gain national power. Location has an important bearing on foreign policy of a nation. The relation between foreign policy and geographic location gave rise to the discipline of geopolitics.
The presence of a water obstacle provided protection to nation states such as Great Britain, Japan, and the USA and allowed Japan to follow isolationist policies. The presence of large accessible seaboards also permitted these nations to build strong navies and expand their territories peacefully or by conquest. In contrast, Poland, with no obstacle for its powerful neighbours, even lost its independence as a nation, being partitioned among the Kingdom of Prussia, the Russian Empire, and Austria from 1795 onwards till it regained independence in 1918.
Power Grid is the English-language edition of the multiplayer German-style board game Funkenschlag (in its second incarnation) designed by Friedemann Friese. Power Grid is published by Rio Grande Games.
In the game, each player represents a company that owns power plants and tries to supply electricity to cities. Over the course of the game, the players will bid on power plants and buy resources to produce electricity to provide power to the growing number of cities in their expanding network.
The game comes with a double-sided board with a map of the United States of America on one side and Germany on the other. Each map consists of six regions featuring cities with connections of varying costs between them. The number of regions used is based on the number of players. Map design itself is a key feature in the strategy of game play as some areas of the map feature generally higher connection costs compared to other areas of the map.
The game is played in rounds, with each round consisting of 5 phases:

A power company in the Midwest hired a group of white hat hackers known as RedTeam Security to test its defenses. We followed them around for 3 days, as they attempted to break into buildings and hack into its network, with the goal of gaining full access. And it was all much easier than you might think. Based on our experiences, it would seem that power companies need to step up their game in the fight against cyber attackers or it could be "lights out."

The conventional synchronous generator has been the backbone of power system operation since its creation – simultaneously providing both the energy and ancillary services that ensure reliable customer supply. Chief among these essential ancillary services is synchronous inertia, a physical property that limits the rate of change of frequency following a large disturbance (e.g. loss of generator, load or interconnector). Worldwide, levels of online synchronous inertia are in decline as more renewable asynchronous generation is added (e.g. wind turbines, solar photovoltaics) and the importance of associated new ancillary service technologies increases (e.g. demand response). As a consequence, new strategies are needed to ensure electrical grid operational security during times of low syst...
Understanding the national power grid and how it impacts timeframes for power restoration to occur
nvestment in renewable energy infrastructure was higher than in fossil fuel infrastructure. With grid-scale energy storage, intermittent sources of renewable energy, such as wind and solar, become viable for the grid. VLAB will examine the technology and economics to make this transformation possible. The global market for energy storage services could be worth as much as $31.5 billion in 2017, according to Lux Research. Additionally, Pike Research forecasts that $122 billion will be invested in energy storage projects between 2011 and 2021. Today, 99% of the global energy storage is pumped hydro, which is geographically constrained. Now entrepreneurs free us from this constraint with fundamentally new technology challenging conventional expectations of capacity, efficiency and product ...

A talk given at Dartmouth College by Jeff Dagle of Pacific Northwest National Laboratory Wednesday January 23, 2013 Co-sponsored by the Institute for Security, Technology, and Society and the CS Colloquium Abstract: The interconnected electric power grid was recently recognized by the National Academy of Engineering as the greatest engineering achievement of the twentieth century. It has achieved high levels of reliability through the rigorous application of robust engineering principles relating to implementing resilient design practices. For example, wide-area communications are often limited to supervisory control functions that supplement localized closed-loop control systems organized in a hierarchical scheme. This enables some global optimization by changing local set-points withou...

Dr. Rik W. De Doncker spoke on Friday, September 14th, 2012 at 1:00PM in BTEC, Room 135 Future electrical power sources will be more decentralized to capture renewable power or to increase exergy by combining heat, cooling and power generation. At the load side, it is anticipated that heat demand for new build city quarters will go down while cooling power will go up. Clearly, local power supply and demand will not be balanced to each other. Under these conditions it makes sense to rethink the way electrical distribution grids in cities and low voltage grids in buildings are designed. Dynamic control of power flow and storage of energy is needed to maintain proper power quality and achieve high efficiency. Flexible grid concepts for DC distribution systems, using intelligent electronic su...
