Communication Standards for Distributed Renewable Energy Sources Integration in Future Electricity Distribution Networks

Distributed Renewable Energy Sources (DRESs) such as wind and solar are becoming a promising alternative for the energy supply in modern (smart) electricity grids as part of future sustainable smart cities. Successful integration of DRESs requires efficient, resilient, and secure communication in order to satisfy the highly challenging and real-time constraints of smart city applications. Regardless of the various research solutions proposed in this context within the last decade, the relevant standardization is a non-trivial issue and is still in its infancy. In this position paper, we briefly review the currently employed DRES communications standards and identify the gaps in their present status. Finally, we discuss and suggest potential pathways for further improvement.
