Kenny has not ridden in an international race since the Rio Games, where she won the team pursuit and omnium, emulating her feat of four years earlier at London 2012.
After Rio, she took time off to start a family with fellow British rider and husband Jason Kenny but says she is looking forward to pulling on her British race suit.
“I’m looking forward to getting back into the Great Britain skinsuit and racing at the world championships again,” Britain’s most successful female Olympian told British Cycling.
“I returned to training about four months ago, and I’ve been really pleased, and, I guess a bit shocked by how fast my form has started to come back.”
She will join teammate and reigning omnium world champion Katie Archibald in the six-woman endurance squad.
Kenny is expected to race in the women’s team pursuit as Britain tries to win the title for the first time since 2014.
Her husband Jason, a six-time Olympic gold medallist, is part of the men’s sprint squad.
The championships begin on Wednesday.
