Use Cases for Plug-In Vehicle Communication as a Distributed Energy Resource
This SAE Information Report establishes use cases for a Plug-in Electric Vehicle (PEV) communicating with an Energy Management System (EMS) as a Distributed Energy Resource (DER) which must be supported by SAE J2847/3. This document also provides guidance for updates to SAE J2847/2 to allow an inverter in an EVSE to use the PEV battery when operating together as either a DER or as a power source for loads which are not connected in parallel with the utility grid. Beyond these two specific communication objectives, this document is also intended to serve as a broad guide to the topic of reverse power flow.
Rationale: The purpose of this revision is to update the document based on subsequent activities in the area of Distributed Energy Resources (DER) and Vehicle to Grid. IEEE standards have been updated since the last publication of this document and have made significant changes to various DER functions. J2836/3-V2 did not implement some of the DER functions because these were rapidly evolving and had errors at the time however that has been corrected and this revision will bring J2836/3 up to date with the state of the industry.
