Resumo
The importance of renewable energies and energy storage system forming a micro-grid and integrating it to the electrical grid is widely spread. A supervisory system plays a crucial role in controlling, managing, and planning the micro-grid. This paper demonstrates the development of a new custom supervisory system based on Internet of Things (IoT), creating an information sharing environment. The proposed supervisory system is based on open-source tools for a micro-grid, composed of a photovoltaic power plant and a storage system, employing smart devices and making non-smart devices compatible with IoT systems. The new supervisory improves the available system by incorporating new features and devices and increasing the data polling rate when necessary. A comparison between the current supervisory system and the proposed one is performed, showing that the new system is more flexible, easily modified, cost-effective, and more fault-resilient.

Palavras-chave
internet of things (IoT); supervisory system; solar power; Raspberry Pi; node-red; Grafana; energy storage, The main challenges to be surpassed regarding renewable energy sources are availability and cost. Solar and wind resources, for instance, are seasonally and hourly dependent. These can greatly influence the energy generation. The mitigation alternatives to the aforementioned challenges could be supervision, control, and energy storage.
