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…

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 …

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 “rig…

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…

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 t…

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…

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…

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 a…

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 …

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 unpredictabl…

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 y…

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…

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 …
