  PowerDynamics.jl is an Open-Source library for dynamic power grid modeling
built in the latest scientific programming language, Julia. It provides all the
tools necessary to analyze the dynamical stability of power grids with high
share of renewable energy. In contrast to conventional tools, it makes full use
of the simplicity and generality that Julia combines with highly-optimized
just-in-time compiled Code. Additionally, its ecosystem provides
DifferentialEquations.jl, a high-performance library for solving differential
equations with built-in solvers and interfaces to industrial grade solvers like
Sundials. PowerDynamics.jl provides a multitude of dynamics for different
node/bus-types, e.g. rotating masses, droop-control in inverters, and is able
to explicitly model time delays of inverters. Furthermore, it includes
realistic models of fluctuations from renewable energy sources. In this paper,
we demonstrate how to use PowerDynamics.jl for the IEEE 14-bus distribution
grid feeder.
