<p>The authors found differences in resting state alpha power depending on degree of handedness.</p>

<blockquote>
  <p><strong>ABSTRACT</strong></p>
  
  <p><strong>Study Aim</strong>: Frontal electroencephalographic (EEG) alpha band power during rest shows increased right, and/or decreased left, hemisphere activity under conditions of state or trait withdrawal-associated affect. Non-right-handers (NRH) are more likely to have mental illnesses and dispositions that involve such withdrawal-related affect. The aim of the study was to examine whether NRH might be characterized by increased right, relative to left, hemisphere activity during rest.</p>
  
  <p><strong>Methods</strong>: The present research investigated that hypothesis by examining resting EEG alpha power in consistently-right-handed (CRH) and NRH individuals.</p>
  
  <p><strong>Results</strong>: In support of the hypothesis, NRH demonstrated decreased right hemisphere alpha power, and therefore increased right hemisphere activity, during rest, compared to CRH.</p>
  
  <p><strong>Conclusions</strong>: The study demonstrates further support for an association between increased right hemisphere activity and negative affect via an association between such EEG activity and NRH.</p>

<p>Can any one suggest a good article about features of EEG of left-handed people?  </p>

<p>I was surprised when find that there are only few old articles about it. I find only one new article by Propper, Ruth E., et al. (2012). Maybe I miss something.</p>

I haven't read that, but they're likely going to just be correlations that may have little to do with the actual "handedness" difference.  Look into hearing, as a small percentage of left-handed people have their dominant cortices for speech and language shifted to the other side.  This is not a reliable indicator, though, as even most left handed people have the same placement of Broca's area, etc.

It does not matter. I don't interesting in language or motor areas specifically. Not-right handedness is an indicator of not normal (alternative) development of the brain. It must have correlates in EEG.

"It must have correlates in EEG" -- No. It must have some *neural* correlate. EEG can capture only a small percentage of behavioral phenomena due to its relatively course spatial frequency and inability to record activity in more medial brain regions. I'd broaden your search accordingly; perhaps that will lead to more relevant literature.
