Bro grow up its just 5/10 variation. Aren't you taking it little to seriously. :Facepalm:The voltage increased from 228v to 235v in my area around the 9pm mark.
Now the voltage is 222v at 9:40pm, did people turn on the Air conditioners or the utility guys are controlling the output.
At 9:50Pm its now 218v.
The people maintain the grid have taken precautions. My own ups log shows that yesterday it was hovering around 231v and today at the same exact time its now 218v, ,my ups log shows the Hz was 50.2hz today, while yesterday it was 50hz. So clearly the people who are working behind the scenes have reduced or adjusted the output. This type of power reductions was just by mostly turning of the lights. Imagine if all turned off the main mcb or heavy appliances, its no rocket science there will be a imbalance which will effect the voltage and frequency.
Check this thread in team bhp, some have shared info from Ministry of power, there was a 25giga watt of power reduction.

This government website shows the current demand vs yesterday demand state by state
Also of if the grid people who maintain grid and already taken precautions then wtf are you wasting server space with your sh!t.
