On the front lines of the power grid 26.Oct.2011 NYT

Auctions

The article needs a section on how auctions determine which power plants produce how much electricity to meet demand. Demand (and therefore supply) varies day to day and minute to minute. These are some sources, especially the World Bank study on long term auctions, but not much on intra-day auctions to vary power throughout the day:

No section on operation of a grid

eg grid frequency regulation. - Not even in a See also section. Where to look ? - Rod57 (talk) 20:04, 8 December 2015 (UTC)

Confusing wording in topology section

"Most transmission grids offer the reliability that more complex mesh networks provide. The expense of mesh topologies restrict their application to transmission and medium voltage distribution grids. Redundancy allows line failures to occur and power is simply rerouted while workmen repair the damaged and deactivated line."

What does this mean? Most transmission grids are mesh topologies? Or most transmission grids are not mesh topologies, but manage to achieve the same reliability anyway? If the latter, we should say what alternate means are used to achieve this reliability. If the former, we should just come out and state that most transmission grids use a mesh topology.

A second point is that "mesh" is never defined. Rpgoldman (talk) 00:27, 18 January 2016 (UTC)

The phrase: "aeroderivative gas turbines used in jet aircraft;". I think this should be "aeroderivative gas turbines based on designs used in jet aircraft;" but I don't know for sure. Rpgoldman (talk) 05:17, 18 January 2016 (UTC)

definition

I would hesitate to include the power producers as part of the electric grid, just as a matter of semantics. Delivery and production are two separate things even if one depends on the other. The term ‘network’ also relates to interconnectedness and not production. My argument is that the grid is a delivery system of (in this case) wires connecting producers and consumers, and does not include the producers and consumers; it is the name of the thing that runs between them. I do not believe this is made clear in the article.

Images

I used the image with the caption: "General layout of electricity networks. Voltages and depictions of electrical lines are typical for Germany and other European systems." for some academic work in Germany and my professor noted the caption 'Low Voltage (50kV)' this is too high generally for low voltage. He has advised me that Low voltage is less that 1kV, and Medium Voltage is between 1 and 60kV. Thus on my version of the diagram I have changed the image to read Low / Medium Voltage (<60kV). I was not able to attach the image without an account. Sorry. Nathan K. www.madteckhead.com

I updated the image to a .SVG file and cleaned it up a bit using the same values as Nathan K. had. --MBizon (talk) 20:14, 8 March 2010 (UTC)
  • Even knowing that it's German, seeing 250KV labelled "extra high voltage" while more common (in my area) 750KV is barely "high voltage" is quite odd. Perhaps these voltage figures must be removed altogether? East of Borschov (talk) 12:00, 12 June 2010 (UTC)

Iceland is not part of the Nordic grid, could someone please update the image?

World map request

It would be informative to produce a map or series of maps showing the extent of public power grids. This is mostly interesting to show where power grids don't go and where there are interconnection boundaries between grids. -- Beland (talk) 07:13, 1 May 2018 (UTC)

We now have a few continents, but we're missing South America, southern parts of Asia, Africa, and Oceania. -- Beland (talk) 04:56, 18 June 2019 (UTC)
It's mostly a question of just painting colors on the existing map. The real trick is getting hold of the information. I think if you dig around we have maps of India (all one grid), Australia, some parts of central America, all of North America. Not sure we have any current map of China.
