  Ai4EComponentLib.jl(Ai4EComponentLib) is a component-base model library based
on Julia language, which relies on the differential equation solver
DifferentialEquations.jl and the symbolic modeling tool Modelingtoolkit.jl. To
handle problems in different physical domains, Ai4EComponentLib tries to build
them with component-base model. Supported by a new generation of symbolic
modeling tools, models built with Ai4EComponentLib are more flexible and
scalable than models built with traditional tools like Modelica. This paper
will introduce the instance and general modeling methods of Ai4EComponentLib
model library.
