When I press a power button on my Mac mini, it goes to sleep mode and when I press it again, it turns on very quickly. However, after a longer sleep, it hibernates. How can I make this delay longer?

I know that I have tu use pmset but I don't know how exactly. Should I change the standbydelay?

My current config:

Yes, you can increase the standbydelay value:

sudo pmset -a standbydelay 18000

The value is in seconds, so 18000 is 5 hours. sudo pmset -a standby 0 would disable standby mode completely.

See man pmset:

standby causes kernel power management to automatically hibernate a
machine after it has slept for a specified time period. This saves power
while asleep. This setting defaults to ON for supported hardware. The
setting standby will be visible in pmset -g if the feature is supported
on this machine.

standby only works if hibernation is turned on to hibernatemode 3 or 25.

standbydelay specifies the delay, in seconds, before writing the hiberna-
tion image to disk and powering off memory for Standby.

Standby mode is also documented in http://support.apple.com/kb/HT4392.
