Overview of Evolving Distributed Energy Resource Grid Interconnection Standards: Preprint

This paper presents a detailed timeline of evolution, from 2000s to 2018, of distributed energy resource interconnection standards and the research which informed their development. Evolution of a standard for distributed energy resources (DER) is expected to capture and accommodate widely different characteristics presented by them and minimize unique grid integration challenges. This makes development of a uni-form grid interconnection standard for all types of DERs a challenging and ever evolving problem. Grid interconnection standards facilitate their safe and reliable grid integration. This paper presents a review of the research topics being considered in the grid integration of ESSs which will ultimately influence the development of this new standard. It is then shown that the existing DER interconnection standard frame-works can be leveraged for most of these topics with some modifications to accommodate the unique characteristics of ESSs.
