What is The Grid - Visualization Maps

Click For Summary

Discussion Overview

The discussion centers around the concept of "The Grid" as it relates to visualization maps of the U.S. electric grid. Participants explore the definitions, implications, and interpretations of the term "grid" in various contexts, including traditional high voltage transmission systems and modern smart grid concepts.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant shares an interactive map by NPR that visualizes the U.S. electric grid, suggesting it may be of interest to others.
  • Another participant humorously suggests that "The Grid" could be seen as a precursor to the Matrix, indicating a cultural reference.
  • A participant with a background in power engineering clarifies that traditionally, the term "grid" refers specifically to the high voltage transmission system and the power plants connected to it, contrasting this with the distribution system.
  • This participant notes that the NPR map represents the transmission grid, while the distribution system operates differently, typically involving a single wire from substations to consumers.
  • The same participant expresses frustration over the evolving definition of "grid" in the context of the smart grid, which encompasses the entire power industry, including distribution and customer loads, diverging from the original meaning.

Areas of Agreement / Disagreement

Participants exhibit a mix of agreement and disagreement regarding the definitions and implications of "The Grid." While some clarify traditional meanings, others highlight the evolving nature of the term, indicating that multiple competing views remain.

Contextual Notes

There are limitations in the discussion regarding the definitions of "grid," which may depend on context and the specific aspects of the power system being referenced. The evolving nature of terminology, particularly with the introduction of the smart grid concept, adds complexity to the discussion.

What is "The Grid" -- Visualization Maps

As PF grows, so does the number of questions about the "grid". While I was searching the internet for an image of a sagging transmission line to use in another thread, I found this cool interactive map by NPR. I thought I'd post it for those curious.

Here I was thinking it's the precurser to the Matrix...
 
I grew surrounded by such maps of Poland.
 
The meaning is very confused right now. Power engineers like myself traditionally reserve the word grid for the high voltage transmission system, plus the power plants that feed it. Any point A in the grid is connected to any other point B by multiple parallel paths. A copper window screen is a good visual analogy. The NPR map depicts the transmission grid.

The distribution system typically runs only one wire from the nearest substation to your street (except in some high density city centers which use a distribution grid). Thus power distribution and the customer loads are not grid like and thus not considered part of the grid.

However, much recent publicity is about the smart grid. In this context they mean the entire power industry, especially power distribution and customer loads. It is almost the opposite to the original meaning. It drives me crazy. So, watch out for the context to interpret the meaning of grid.
