Source of Power
Parvati represent all form of power or energy. It is believed when shiva lost his first wife he went to a massive depression, in a nearly a Shava(Dead Body / Corpse) It is also believed that without her, Shiva remains as Shava or Corpse, for she is the ultimate source of power for all beings, gods and Devas. She brought back shiva from that Shava(Corpse)mode to Shiva.

That is why she is considered as goddess of power. Indeed, she is most powerful of all. When her anger reaches its peak, she can destroy the whole universe, gods and Trimurti in just seconds. Even Trinity i.e. Brahma, Vishnu and Shiva, never try to make her angry at any cost.
