Is there any report or technical document or scientific paper that explains the internal power supply architecture of the data center (from utility supply to downstream up to servers)?
Thanks in advance.
A few suggestions:
This white paper from Schneider Electric, which does a lot of Data center electrical work, gives an overview but more importantly at the end has links to other more detailed white papers:

Here is another overview from another company, which draws a lot from the Uptime Institute, another place I suggest you look:

We are going to publish soon our use of Fuel Cells in our data centers and more on our facility design - I will share those links here when the papers are published.
Note also that the design can vary by geography - in Silicon Valley the power is very clean and reliable and you don't always need to condition it. In other geographies, not so much. You will see this in the papers we will release.
Hello Jeff Sedayao,
Thank you for your suggestions. I will wait for your upcoming paper.

It doesn't show diagrams going all the way to the server, but it does have some high level diagrams of how power is fed from fuel cell sources in conjunction with utility power to inside the data center.
Coming from a practical commercial background of systems and data centre administration my first port of call would be commercial white papers on continuity and stability of supply.
Siemens and the aforementioned Schneider Electric are by far the biggest players in the field having absorbed smaller manufacturers between them, but there are others. Although perhaps not academically ideal you should be able to find plenty of sales-oriented reference architectures to draw from in the public space.
Vertiv and Riello are smaller players in the uninterruptible supply market.
To get a picture of power distribution and control at the granular level of racks and individual servers look to rack PDU suppliers like Eaton or APC (which is a Schneider subsidiary, and also brands smaller scale UPS devices).
And of course Gartner are a good place to look for market overviews as a starting reference point.
None of this answers your question directly, but hopefully it will provide the means to gather your own information.
Kazi Main Uddin Ahmed: We ended up correcting a few errors in the paper, and we added some detail in some diagrams that might be of interest, such as block diagrams of equipment types going from utilities to servers. This are publicly viewable now:
