I think your interpretation is correct. The voltage control is done at the high level of the grid, meaning the control covers bigger generation stations and major substations. Even if it’s small generator, rotating machinery, you won’t have

Hoping this forces universities to change their archaic PhD system, to adapt something similar to european system. Then people who really have passion for a field and want to have normal job do their research, without working for labs as a

This book is geared to prepare you for functional analysis in a fast pace. It won’t take you so far in applied math, engineering or ML. Considering this, not sure the title is “right”. You can still find books that use the same approach and

Those are actually good questions. Engineering grid and PV installations acknowledge that the generation may be lost, so you are having contingency plan by means of transferring or picking the load. You're going to lose power for short

My point is hacking into home PV inverters doesn’t affect grid stability, you can’t penetrate into grid in that way. At worst we’re talking about losing power for a short time at those homes. When the demand is planned for a region you spec

Reading through comments I saw a lot of comments confusing cloud security with electrical safety of a system. Electrical protections are completely separate from communication line/ internet, has to be hard wired. As the size of plant&

In greater scale, meaning power plants not the PV installed at houses, these things are taken more seriously and after purchase of equipment the control and automation of plant are in your hands. For example, Woodward, ABB have products wit

That makes sense, I'm in EST. Just to clarify and understand what happened, I believe right after the trip some generators all around the grid picked up the load (unless UFLS was activated) immediately (around 7:03), we can call these

Those links are very informative. Can you elaborate on Ancillary Services Monitor and Energy Storage Resource Action dashboards? What’s the installed capacity that supported? Also your original post link states event happened at 7:02 AM, yo

You’re correct that the system is statistical, and it’s planned accordingly. However, we cannot omit the fact that it’s the running turbine that responds faster to the unpredictable nature of the grid. The backbone of the grid, aka the base

I think you’re missing the point how turbine-generator works. The rpm speed has to stay the same, meaning the rotor speed doesn’t change. As long as you don’t have closed circuit you’ll waste that mechanical energy. If you meant starting fr

My understanding engine is a device governed by laws of thermodynamics, whereas motor is based on electrodynamics. Always thought calling car engine a motor is incorrect, shouldn’t be used interchangeably. In my experience machinery would b

No it’s not. You can argue about number theory and combinatorics, but the stats/prob part of the book is very inadequate.

I’m not saying it will not have any impact, but will it be at the levels mentioned in the report? My consideration depends heavily on engineering of it. For example, applying this in NYC is almost impossible, and dangerous for the system. A
