undergraduate - Attending conferences as a first-year undergrad

I'm a first-year undergraduate student in physics. Since starting my studies I've tried to get involved in research as much as possible. Recently, the team I work with encouraged me to submit an abstract about my current project (which is the first serious one that I've taken on) for an upcoming conference. I did and I got accepted with a poster.

Now my question is: How should I approach this to benefit the most? Or maybe there isn't even a point in me going at all?

I'm under the impression that most of the typical advantages of attending a conference such as networking, or keeping up-to-date with recent advances aren't really applicable to me as I simply lack the necessary knowledge. So far I've only taken a basic mechanics course and I have some working knowledge that I've acquired while working at the lab but nothing beyond that.

Additional information: the conference is obviously not a high-tier one. Judging by previous editions, about 150 attendees are expected, around 1/3-1/2 of that international (this is all in Europe by the way). Travel funding is provided by our department [active participation, in form of a poster, was part of the requirements to get that funding].
