Distributed/decentrallized power generation vs. Regional power generation

In summary, the conversation discusses the differences between distributed and decentralized power generation, as well as the concept of regional power generation. While distributed generation refers to the production of electricity on medium/low voltage levels, decentralized generation involves generating power on independent small-sized units. Regional power generation, on the other hand, refers to generation connected to high voltage lines/grid. The conversation also touches on the idea of small modular nuclear units being used in remote regions or offshore locations where fuel delivery is difficult. However, there are concerns about the cost and security of nuclear waste handling.

Hello everyone!
Need help with understanding the terms "distributed/decentralized" vs. "regional power generation".
1. Is there any difference between the terms "distributed" and "decentralized" generation (of electricity)?
I thought "distributed" means generation of electricity on units joint in a grid, whereas "decentralized" means generating power on independed small-sized units.

2. Does the term "Regional power generation" exist at all?

Thank you

It is my understanding that distributed generation is done on medium/low voltage levels. That is on a line (radial) with loads connected along the line (before and after the generator(s)). This can cause problems with voltage magnitude and protection of lines, among many other problems.

Regional power generation refers to generation connected (only) to high voltage lines/grid.

But there may be other definitions that is correct.

Thank you.
I do not know if I'm asking in the correct thread, but my question mostly relates to nuclear generation. There is such a tendency now that small-sized modular units are designed over the world and they are intended to operate either in local grids or individually (e.g. in off-shore oil rigs, or in remote regions whereto fuel is hard to deliver and nuclear generation becomes competitive).

Please, opinions are welcome!

My statement does not differentiate on what type of fuel used in generator.

I'm not familiar with small nuclear units, except at ships/sub. Although they are not "small" they either.

But if the transfer capacity of a tie-line between areas limits the loading in one remote area, then installing a generator unit without upgrading the line might be a effective measure (w.r.t. cost, environment e.g.).

But isn't nuclear waste handling and security very expensive? Thus 1 large station is more effective than 10 small?

Do you have a reference? Especially for offshore nuclear generation?

"Small" is just a term. It's used for reactors below 300 MW.

Can't say much about off-shore generation. Just know that such possibilities are being studied.

FAQ: Distributed/decentrallized power generation vs. Regional power generation

What is distributed/decentralized power generation?

Distributed/decentralized power generation refers to the production of electricity from multiple small-scale power sources, such as solar panels, wind turbines, or micro-hydro plants, located close to the point of consumption. This is in contrast to regional power generation, which involves large-scale power plants that supply electricity to a wider geographical area.

What are the advantages of distributed/decentralized power generation?

One major advantage of distributed/decentralized power generation is its resilience. Since the power sources are spread out, there is less risk of a single point of failure causing a widespread power outage. This also makes it more secure against cyber attacks. Additionally, distributed power generation can reduce transmission and distribution losses, as the electricity is produced and consumed in the same area.

What are the disadvantages of distributed/decentralized power generation?

One disadvantage of distributed/decentralized power generation is its higher initial cost compared to regional power generation. Installing multiple small-scale power sources can be more expensive than building a single large-scale power plant. There may also be challenges with integrating these different power sources into the existing grid infrastructure.

How does distributed/decentralized power generation impact the environment?

Distributed/decentralized power generation can have a positive impact on the environment, as it often involves the use of renewable energy sources. This can help reduce carbon emissions and mitigate the effects of climate change. However, the environmental impact may vary depending on the specific power sources used and their location.

What is the role of government in promoting distributed/decentralized power generation?

The government plays a crucial role in promoting distributed/decentralized power generation by creating policies and regulations that support its development. This can include providing incentives for the use of renewable energy sources, implementing net metering programs, and supporting research and development in this area. The government also plays a role in ensuring that the grid infrastructure is able to accommodate and integrate these smaller power sources.
