Talk:Power system reliability

Merge proposal

Electrical grid security in the United States has a lot of detail that could be here. I don't see why the article should only cover the United States. The information can be useful here. I know this article doesn't cover physical security, but there's no reason for it not to. 134.215.176.89 (talk) 21:50, 18 February 2024 (UTC)

Strongly oppose There is a pretty confusing, but very widely used in the field, term "grid security" (currently a section in this article, but fully deserving an article of its own) that has very little in common with the physical security (see Power system reliability#Security). I think about it in terms of armored vehicles: in order to operate, they need a reliable network of support ("logistics security" in the form of repair shops, fueling depots, etc.) and physical security (infantry support, etc.). While without either one the vehicle becomes a useless heap of metal, these two issues have little else in common. Just like it is hard to imagine an article that covers both infantry tactics and fuel logistics, I see little synergy between expanding the generators/transmission facilities and protecting these same facilities from misfits. The fact that in both cases the same word "security" is used is a pure coincidence, IMHO. For the avoidance of doubt, this comment assumes that the merge proposal involves this article. I have no position on other merge discussions that are hinted at in this request, see some of them on Talk:Electrical grid security in the United States (perhaps this request should be moved there, too?).

Closing, given the uncontested objection and no support, with discussion stale for many months. Klbrain (talk) 16:34, 6 October 2024 (UTC)

Methods

A new Methods section was added recently. IMHO there are some issues with it, as it seems to be written by an AI model. Pinging @Freshman404: For example, the Distributed Energy Resources are described as an advantage (integration of Distributed Energy Resources (DERs), such as solar panels, wind turbines, and battery storage, into the power grid provides localized generation that enhances system reliability), while typical industry position on them is that they present challenges for reliability (the grid-scale batteries help a lot, but they are centralized). I will add an oft-cited review source on the subject. Викидим (talk) 17:18, 3 June 2025 (UTC)

@Викидим: Thanks for your comment. Let me clarify: DERs are helpful for improving the reliability of the system by providing additional power sources in a fault event, which means we might be able to isolate the fault and provide power using the available DERs in cases that fault isolation interrupts the main feeder (cuts the power supply path from the main grid). The issue you're talking about is stability of the grid, not reliability. For stability, there are many studies that you can find out how engineers are coping with the issue with designing better controllers. Here's a couple of articles you might like to read to learn more (Increasing reliability using DER and stability issues) Let me know if you want to know more about this topic.Freshman404^Talk 17:15, 4 June 2025 (UTC)

I have looked at the sources you have provided below and do not understand how these sources are related to the topic of this article, the grid reliability:

1. The Marqusee & Stringer seemingly discuss the backup power systems. While these obviously greatly improve the reliability of the power supply for a particular hospital or household, they only kick in once the grid is already down and thus do not contribute to the reliability of the power system as a whole.
2. Basu et al. are, similarly, discussing microgrids. Again, unless from the beginning this is an autonomous system, getting into the microgrid situation implies extreme degree of islanding, with large portions of the grid down: if there is a problem with grid balancing in the whole grid, islanding out areas with sufficient generation will obviously hurt the rest of the system.
3. s Alvarez et al. do not seem to suggest that the stability will improve with adding the DER. They appear to assume that a DER would easily trip in th fault situation and are trying to propose better estimates for the chance of tripping. If I missed skething, could you let me know the chapter and veser
4. Hosseinzadeh et al. also discusses the microgrids.

All said, could you please also comment on my understanding that the added text is a product of a generative AI?
