Inverter Commanded by Internet of Things Protocol

Abstract

The growing presence of Distributed Energy Resources poses challenges for real-time monitoring, control, and integration into smart grids. Effective communication is essential to ensure interoperability and grid stability. This work presents a complete stack solution for DER converter control, combining power electronics hardware with secure MQTT-based communication and a user interface. A real-time controller manages the converter, while an application processor calculates and transmits electrical statistics over a TLS-secured MQTT. Server-side, a microservice architecture stores data in InfluxDB and visualizes it in Grafana. Bidirectional communication allows real-time control and monitoring, demonstrating the role of modern protocols in enabling scalable DER integration.
