Interoperable DER Gateway: Connecting Grid Commands to Battery Systems

- Public repository, in development
Renewable energy systems are becoming more sophisticated, but integrating different devices and communication protocols remains an important engineering challenge.
A utility or distributed energy resource management system may communicate using one protocol, while a battery management system exposes its controls through another. Without an integration layer, translating commands between these systems can become difficult to manage.
This is the problem behind my Interoperable DER Gateway project, which I am developing in connection with work involving Invinity Energy Systems.
The goal is to build middleware that bridges IEEE 2030.5 utility or DER management commands with the Modbus TCP interface used by the Invinity Endurium battery management system.
In practical terms, the gateway is intended to help translate external control instructions into commands that the battery system can understand, supporting automated battery scheduling.
What I am working on
- Protocol translation
- Connecting two different communication interfaces through a defined software layer.
- Automated scheduling
- Supporting the translation and handling of battery scheduling instructions.
- Safe operation
- Accounting for operating limits, system faults, and conditions in which a requested action should not be executed.
- Reliability and recovery
- Considering what happens when a connection fails, a command cannot be completed, or the system needs to recover from an error.
- Modular architecture
- Keeping the integration components organised so that they can be tested and maintained independently.
The dashboard is another part of the project, providing a visual interface for the system. It helps present the project as more than a background integration service, although the exact functionality depends on the implementation currently available.
Why this project matters to me
This project brings together several areas that I am interested in: software architecture, communication protocols, energy storage, and the practical challenges of connecting digital systems to physical infrastructure.
It also changes how I think about software reliability. In a conventional web application, a failed request might mean that a user has to retry an action. In an energy control system, a failed or incorrectly handled command can have operational implications.
That makes validation, fault handling, clear system states, and safe behaviour important design considerations from the beginning.
The project is still under development. I am treating it as an engineering integration project rather than claiming that it is already deployed in a production utility environment.
What this project represents: My interest in building software that connects digital infrastructure with real-world energy systems.
