My Nikon D7200, when using shutter priority, the exposure compensation always automatically becomes very low and cannot be adjusted back.

It’s not that the exposure compensation is very low, but because the lens aperture has a maximum value.

For example, if your lens is a kit, the maximum aperture is f3.5. If you set the shutter priority to 1/60 second and ISO200, it will be impossible to get a bright picture at night anyway. All you have to do is raise the ISO and the picture will brighten up.

If you don’t increase the ISO, it will be useless no matter how much you increase the exposure compensation at this time. Because your lens and your shutter determine that you can only shoot so dark. Either lower the shutter tripod or raise the ISO.

There are only three things that determine the brightness of the picture, aperture, shutter, and ISO. Exposure compensation is a convenient way for you to adjust the brightness when all three are sufficient.

For example, if you set shutter priority 1/60, aperture F8, and ISO800 to take pictures, when you increase the exposure compensation by +0.3, the aperture will automatically reduce to F7.2, and the other two parameters will remain unchanged. Essentially, it's because you use a wider aperture, the picture becomes a bit brighter, not because you use +0.3 exposure compensation.
