Overview
IEC SRD 63443-1:2026 - Distributed Energy Resource Aggregation Business – Part 1: System Architecture and Service Scenarios establishes terms, system components, and typical service scenarios for distributed energy resource aggregation business (ERAB) systems. The standard defines the interoperability and architecture for integrating distributed energy resources (DER), controllable loads (CLs), advanced metering infrastructure, and aggregation functions. It also explains the concept of the Virtual Power Plant (VPP), where a group of distributed resources is managed to function as a dispatchable energy unit within modern power systems.
This standard is essential for energy market participants, utility operators, service aggregators, and technology providers aiming to enhance grid flexibility through demand response, distributed generation, and smart metering solutions.
Key Topics
- System Architecture: The standard details a five-level system architecture, covering DERs and controllable loads at the customer premises, ERAB controllers and servers, operational grid management by system operators, and market operations.
- Core Components: Key elements include:
- Distributed Energy Resources (DER) like renewable generators and storage.
- Controllable Loads (CLs) such as HVAC and lighting.
- ERAB Controller for data collection and resource control.
- Smart Meter (advanced metering infrastructure) at the Point of Common Coupling (PCC).
- Service Scenarios: ERAB provides two main services:
- Demand Restraint (DR): Reduces peak load and maintains grid balance.
- Demand Increase (Elevating DR): Shifts or increases consumption during times of excess supply (e.g., high renewable output).
- Performance Measurement: The ERAB relies on real-time smart metering data at the PCC and, optionally, metering at individual DER/CL points. This ensures accurate evaluation of demand response actions and supports transaction settlement.
- Key Stakeholders: The architecture supports interactions among Transmission System Operators (TSO), Distribution System Operators (DSO), electricity suppliers, energy exchanges, prosumers, and aggregators.
Applications
- Virtual Power Plants (VPP): The ERAB system underpins the aggregation of DERs and controllable loads, enabling coordinated participation in electricity markets as a virtual, dispatchable unit.
- Demand Response Programs: Aggregators use the framework to deploy demand response services, including both incentive-based peak load reduction and frequency restoration.
- Grid Flexibility: Utilities and operators use ERAB to access real-time data and remotely control consumer-side resources, enhancing grid stability and integrating higher shares of renewables.
- Energy Trading and Settlements: Market participants leverage standard-compliant measurement and control functions for transparent, reliable energy exchange and compliance.
- Prosumers and Industrial Sites: Enables optimized local resource management, allowing prosumers and commercial entities to participate in ancillary service markets via the ERAB platform.
