  Since the energy domain is in a transformative shift towards sustainability,
the integration of new technologies and smart systems into traditional power
grids has emerged. As an effective approach, Petri Nets (PN) have been applied
to model and analyze the complex dynamics in Smart Grid (SG) environments.
However, we are currently missing an overview of types of PNs applied to
different areas and problems related to SGs. Therefore, this paper proposes
four fundamental research questions related to the application areas of PNs in
SGs, PNs types, aspects modelled by PNs in the identified areas, and the
validation methods in the evaluation. The answers to the research questions are
derived from a comprehensive and interdisciplinary literature analysis. The
results capture a valuable overview of PNs applications in the global energy
landscape and can offer indications for future research directions.
