DERMS: Driving Electric Utility Grid Modernization

Integrating Innovation, Efficiency, and Sustainability in Modern Grid Management

I. Introduction

  • Definition and Importance of DERMS

DERMS (Distributed Energy Resource Management Systems) are intricate combinations of hardware and software applications designed to ensure utilities can manage the distribution system effectively and safely, even with a high penetration of Distributed Energy Resources (DERs). These systems analyze both historical and real-time data to aid in the seamless integration, management, and control of flexible and intermittent DERs, as well as overall electric demand.

The primary function of a DERMS is to process and interpret data, transforming it into actionable intelligence. This intelligence is crucial for maintaining a balanced and efficient transmission and distribution system. By synchronizing supply and demand, DERMSs help optimize power flows, effectively managing electric demand, DERs, and traditional centralized generation sources.

The actionable insights derived from DERMSs are applied to keep the distribution network in harmony, ensuring a stable and reliable energy supply. This optimization extends to various aspects of the power grid, including enhancing the integration of renewable energy sources, improving grid resilience, and reducing operational costs. In essence, DERMSs play a pivotal role in modernizing the electric grid, making it more adaptive to the evolving landscape of energy production and consumption.

  • Overview of Distributed Energy Resources (DERs)

    • Distributed Energy Use Cases (e.g., DE Management, VPP, Microgrids, Distribution-level automation, etc.

  • The Role of DERMS in Modern Grid Management

    • DERMS manages DER and DER Aggregation lifecycles from registration to supply of grid services and settlements and provides for integration from IoT devices to markets and across utility enterprise systems.

    • Grid DERMS vs Grid-Edge DERMS

        • Grid DERMS and Grid-Edge DERMS are both types of Distributed Energy Resource Management Systems, but they focus on different aspects of energy resource management within the grid.

        • Level of Operation: Grid DERMS operate at the utility or distribution grid level, focusing on system-wide stability and optimization. Grid-Edge DERMS operate at the local or individual asset level, focusing on managing customer-owned DERs and engaging end-users.

        • Integration and Control: Grid DERMS are integrated with central utility control systems and focus on large-scale grid management. Grid-Edge DERMS interact directly with end-user devices and often provide more localized control and optimization.

        • Customer Interaction: Grid DERMS has limited direct interaction with end customers and focuses more on utility operations. Grid-Edge DERMS engages directly with customers, facilitating their participation in grid services and demand response programs.
