Query: Modeling the dynamics and control of power systems with high share of
  renewable energies   A challenge for renewable and hybrid power systems is the dynamically stable
integration of Renewable Energy Sources (RES). This paper specifically
investigates the influence of intermittent RES and measurement delays from
power electronic resources on frequency stability. In addition it presents an
Open-Source framework to undertake dynamic RES modeling.
  First, for local intermittent fluctuations in lossy distribution grids I find
a remarkable and subtle but robust interplay of dynamical and topological
properties, which is largely absent for lossless grids.
  Second, I show how delays may induce resonance catastrophes and how the
existence of critical delays sets an upper limit for measurement times.
Further, I investigate whether centralized vs. decentralized power production,
for different grid topologies, changes this behavior.
  Third, the code used for producing the above results is in the process of
being published as an open-source Software framework called PowerDynamics.jl
being developed in the programming language Julia. It will cover the rich novel
dynamics caused by the integration of RES with the implementation of
Differential Algebraic (DAEs), Delayed Differential (DDEs) and Stochastic
Differential Algebraic Equations (SDAEs).
  Altogether, this paper investigates the stability of future power grids
moving towards integrating more aspects of renewable energy dynamics and
presents an adequate modeling framework for RES integration studies.
