The adoption of standardized Web Service communication protocols from manufacturing and automation industries carries a number of currently unused potentials for energy distribution processes. This work addresses potential advantages of such an approach, particularly highlighting benefits for medium-term, wide-spread use of Distributed Energy Resources (DER). Therefore a new communication protocol mapping for IEC 61850 is introduced based on the Devices Profile for Web Services (DPWS). Other than currently specified mappings, this approach benefits from intrinsic compliance to WS-* protocols. It brings along numerous advantages like plug and play field deployment of Intelligent Electrical Devices (IED) and more efficient asset management through seamless enterprise IT integration. Next to detailing this new mapping in theory, an increasingly important DER use case scenario based on fully electric vehicles (EV) is conducted as proof of concept. This use case also serves as evaluation scenario focusing on latency and scalability issues of the discovery process of dynamic DERs.
