Grid Services from DER Device Fleets

This project aims to enable a broad range of devices – principally distributed energy resources (DERs) – to provide much of the operational flexibility required by the power grid in the form of a growing number of increasingly valuable services at the bulk system and local distribution levels. To achieve this goal standard methods are needed for modeling the ability of individual devices of various classes to respond to provide grid services. This report details a general, standard device model with a battery equivalent interface applicable to each device class. This model is designed to be modular and readily incorporated in grid planning and operational tools. The functional objectives, requirements and architecture for the modeling framework are presented along with example model instantiations for eight different DERs
