I had a power cut 5 times today while i was playing on my ps4

Solution
Yes, it can cause serious damage. Especially so if the power goes off and immediately come back on before the machine has spun down.

You can mitigate the problem with an uninterruptible power suppy (UPS) which will keep it powered long enough for a normal shutdown. While a surge suppressor won't allow the normal shutdown, it can prevent surges that occur when the power comes back on from damaging the equipment.
