  This article develops a practical technique for studying representations of
$\Bbbk$-linear categories arising in the categorification of quantum groups. We
work in terms of locally unital algebras which are $\mathbb{Z}$-graded with
graded pieces that are finite-dimensional and bounded below, developing a
theory of graded triangular bases for such algebras. The definition is a graded
extension of the notion of triangular basis introduced in previous joint work
with Stroppel. However, in the general graded setting, finitely generated
projective modules often fail to be Noetherian, so that existing results from
the study of highest weight categories are not directly applicable.
Nevertheless, we show that there is still a good theory of standard modules. In
motivating examples arising from Kac-Moody 2-categories, these modules
categorify the PBW bases for the modified forms of quantum groups constructed
by Wang.
