scope:

This document provides a guide for the development of a functional specification for distributed energy resources (DER) management systems (DERMS). It includes guiding principles for the application and deployment of DERMS and DERMS control systems, addresses the basic functional requirements, and proposes a set of core functions. These include: DER discovery, visualization, and monitoring of active and reactive power flows and voltage at specific nodes; DER production estimation and scheduling, and dispatch of active and reactive power; DER ancillary services provision, including voltage and frequency control/support. The approach is extended to virtual power plant (VPP) control systems.

Purpose

The purpose of the DERMS is to aggregate and dispatch multiple DER, coordinate their operation in the electric system, and optimize their output. With the increased deployment and penetration of DER, aggregation of DER can be an effective approach to integrate DER into the planning and operation of distribution systems and transmission systems.
