Integrating Industry 4.0 approaches into Low Voltage Grids: A Cost-Efficient Retrofit Strategy Using IoT and Edge Computing

This paper presents a cost-efficient retrofit strategy for the digitalization of low voltage grids, leveraging the advancements of Industry 4.0 technologies such as Internet of Things (IoT) and edge computing. Facing the challenges of traditional grid management systems, like scalability, data processing, cybersecurity, and integration of renewable energies, this strategy proposes a practical solution to enhance grid observability. By implementing this approach in a local grid station and two cable distributors, we illustrate the potential for significant improvements in grid management, including real-time monitoring of power consumption and energy feedback. The findings underscore the transformative impact of digital technologies on the energy sector, offering insights into the future of grid management and the integration of renewable energy sources. This study contributes to the evolving discourse on grid digitalization, providing a framework for deploying IoT and edge computing in low voltage grids to achieve a more sustainable and efficient energy future.
