Perhaps Percy was kicked out because of a prophecy that the camp elders misinterpreted. They thought that Percy's presence would bring great danger to the camp, so they made the hasty decision to expel him. It could also be that there was some sort of political intrigue within the camp.

A plot could be that Percy accidentally breaks an ancient and sacred rule of the camp while trying to save a fellow camper. As a result, he's kicked out.

He may also have some internal struggle about whether to forgive the betrayer if the situation allows for it.
One possible reason for Percy being kicked out in fanfiction could be that he was wrongly accused of stealing a powerful artifact from the camp. Maybe someone framed him to get him out of the way.
