Architecture and use-cases for EVs to provide grid support functions. | Status: Current

1 Scope The scope of this document is the assessment of how electric vehicles (EVs) can act as distributed energy resources (DER) when they are interconnected to the electric power system for charging or discharging, whether in the home, in an office complex, in shopping centres, or in EV charging stations. Although clearly the main purpose for EV interconnection to the grid is to charge their batteries, EVs can provide grid support functions while interconnected, and in some situations, can be mandated or incentivized to do so. This document provides use cases as examples of how EVs might provide such DER functionality, based on the grid support functions defined in IEC 61850‑7‑420, IEEE Std 1547:2018, and EN 50549.
