DERMS vs ADMS

DERMS (Distributed Energy Resource Management System) and ADMS (Advanced Distributed Management System) will be the primary applications or tools for electric utilities now and in the future.

A Distributed Energy Resource Management System (DERMS) is a software solution for controlling and coordinating a variety of distributed energy resources (DERs).DERs include solar panels, wind turbines,?energy storage?systems (e.g., batteries), electric vehicles, and more.

The primary role of a DERMS is to manage the DER-specific information flows. The full lifecycle of an individual DER is tracked and managed from the time a DER is registered and comes online (or is unregistered/uncontrolled and added to a customer's system) until the DER reaches the end of life and is retired. One critical consideration is the scaling that may be required for DERs. While the ADMS may track the characteristics of individual customers (or meters) that run into the millions, each customer can represent multiple DER types, including one or more demand response (DR) devices (A/C, water heater, pool pump, etc.), residential or commercial PV, energy storage batteries, and more, which may be in the tens of millions.

The traditional role of an ADMS is to provide tools and situational awareness of the distribution system and to safely and efficiently manage switching and tagging, manage system restoration after storms or other unexpected events, and ensure power quality for every customer. The ADMS also enables control of the system for centralized volt-var control and automated fault location, isolation, and service restoration. The primary role of an ADMS is best described as one of ensuring the reliability and security of the distribution system.
