Would be nice if you could elaborate better on "Usually a raise in our company is between 5-15%.".
As a general opinion, I'd often say that "someone feeling unappreciated for not getting a raise on the first year" is an absurd complaint. In industries I've worked or known people, either:
Nobody gets a discretionary raise within their first year (exceptions for people who receive offers to change jobs, or who have a stellar performance, to the point he's working for five very good employees.
If there is an expected yearly raise, so everybody gets one every year with no prejudice to inflation correction law-mandated raises or discretionary raises, then the raise is in the range of 1% to 3%, with a 5% value being a once in a lifetime recognition that you are doing great (and probably others are doing bad).
You get a somewhat expected promotion. Think intern becoming engineer or "junior analyst" becoming "analyst" or "senior analyst". This happens when you are basically hired under some special probation, in other words, the company hires lots of people on a low salary, fires most of them but gives significant raises to keep the actual (hard to find) good ones.
So first you need to know which case is yours. Then you need to actually know how salaries work in your company. Is there a clear-cut policy on how much someone's salaries should change over time and promotions? Some companies have rules stating that nobody can receive a promotion in less than X time and you may have already been hired at the top of your payment bracket.
Then, there are plenty of answers on this site about asking for a raise. And a lot of people recommending that if you want to get paid more, you should switch jobs.
Also, in general, if you accept a job, it is understood that you are satisfied with the payment you'll be receiving in the short term, obviously, you can aim for more in the medium to long term, but one year is short term. Think as well if the achievements you've made during this year are actually the results of your skill and dedication, and not the effect of support and luck. Sometimes praising your job makes your boss look good as well, not just you.
