What I need:
no linegap for reference section. Unable to get proper result using this.
increase space between two bib items.
It is preferable if don't need to change linespread every time. From here Miktex doesn't have bibspacing package. and alternative approach says "Command \bibitemsep already defined. \newlength{\bibitemsep}"

setspaceto do the spacing for you: Double line spacing, but maybe you shouldn't. (http://www.tex.ac.uk/FAQ-linespace.html) – moewe Apr 06 '17 at 14:47
