What you're describing is the result of noise on the power lines supplying power to your neighbourhood. Usually people find that their system sounds better in the evening after a lot of industry has shut down for the night, people have finished cooking their meals and eating/washing up, and the demand on the grid has dropped significantly.
You can't prevent the problem because the problem is caused by everyone on the grid, and while everyone else individually is making things a very little bit worse for you it's also true that your home is contributing a very little bit to making things worse for everyone else and a lot of people, each contributing a very little bit to a problem, end up making the problem bigger. Also, other electrical devices in your home are pumping noise into your household circuits which is being passed to your system. One thing you can do is to have an electrician instal a separate line from your mains board to a wall connection for your audio system so that the power supply to your system is isolated to a degree from every other electrical device in your home.
After that, or instead if you wish but I think having the separate line to your system is the best start and also the cheapest option you can also consider cleaning up the power going to your system even further with a power conditioner. There are lots of them out there and they all make different claims. The good ones are helpful, the bad ones do little, and I haven't tried them all. Judging from comments from users here, we've got members who are very happy with products from Audioquest, PS Audio, and Shunyata (listed in alphabetical order because I have only heard PS Audio out of those 3 brands and they seem to be the big names at the moment though there are lots of others). They each use different approaches and availability can depend on your location. For example Audioquest power products aren't available in Australia where I am and not all Shunyata models are available.
If you want to try one, consider what's available in your area and whether you can borrow one for a trial, and also consider the number of power outlets you need for your system. Everyone makes difference models and cost goes up with effectiveness within each manufacturer's range so think of your budget. Try before you buy and try over a couple of days when you're home for large parts of the day so you can see what they do at different times and decide whether they are effective with your power situation.
