To clear up some confussion:

StyleBook property requires an object instance type of TStyleBook so your attempt to pass a string to that property will produce the Incompatible types error.
StyleName is the name by which a style or style subcomponent is known for. I'm not exactly sure why you mentioned the StyleName property as it doesn't seem to have anything to do with your question.

To return to your question, how to load a style into a TStyleBook at runtime and apply it to the Form?

var
  aStyleBook : TStyleBook;
begin
  // Create styleBook and assign the main form as its owner
  aStyleBook := TStyleBook.Create(Self); 
  // Load style from file or Stream
  aStyleBook.Resource.LoadFromFile('...'); 
  // set the loaded style as active style
  Self.StyleBook := aStyleBook;
end;
