Does Enhced Edition of the game include dlc's?

Enhanced Edition refers to a version of the game rather than to a set of content. Every edition you can buy now is enhanced edition.
Which DLCs are included determined by what you are buying. The imperial edition contains all the DLCs except for Kickstarter exclusive items, all the other editions contain no major DLC packs.

Thanks. I wondered if it is something like defenitive edition that I bought pillars in, but I guess it's not.

PF:K's Imperial Edition is equivalent for PoE's Definitive Edition.
