Microgrid Control Based on IEC-61850 Architecture and Petri Net Modeling

Le résumé fourni par la source

The growing demand for more resilient and sustainable energy systems has driven the adoption of microgrids integrated with renewable energy sources. However, the lack of flexible modeling methods still poses a challenge for the design and automation of such systems. This work proposes a Petri Net-based approach to graphically represent the operational states and transitions of a microgrid. As a formal method, Petri Nets provide a mathematically grounded structure for modeling dynamic behavior, enabling precise analysis and predictable control logic. The model is converted into XML (Extensible Markup Language) format PNML (Petri Net Markup Lnaguage) and processed by a Raspberry Pi Pico microcontroller using MicroPython. The system's operation was validated through MQTT communication and LabVIEW monitoring, confirming the correct execution of the modeled transitions. These results demonstrate the feasibility of the proposal as an accessible alternative to FPGA-based implementations and enable clear visualization of microgrid operational dynamics compliant with the IEC-61850 standard. Furthermore, the approach lays the groundwork for future applications based on real-time events, such as current and voltage measurements.
