Using wordpress theme that displays related posts on single post. Every time I refresh the page I see different results for related posts.
Does google penalize the web-page that displays different related posts every time the page is refreshed?

No. This happens on publisher sites all the time, the "top news" story carousel/ link module (whatever you want to call it) updates constantly.
However, if you're looking for static crawl paths, i.e. ensuring you have internal links to said articles, this rotational system is unreliable.
To ensure you have static crawl paths, supplement your rotating related posts widget links with an HTML sitemap at least.
