AbstractThe energy management method called Peak Shaving is a valuable approach, which increases the efficiency of the electricity grid and reduces costs for consumer agents, especially in contexts of high demand. Furthermore, this technique proves to be interesting for the new Brazilian energy challenges. This work proposes to build a computational infrastructure in order to enable the execution of this energy management method through a photovoltaic generation unit. In this sense, the construction of a supervisory will be presented, which will provide a view of the behaviour of the multiple electrical variables, which involve the generation unit, enabling the realisation of the energy optimization technique. This system consisted of a Modbus serial communication, MQTT message protocol, Python programming language, InfluxDB database and the Grafana interactive viewer. The infrastructure development was satisfactory with regard to data monitoring, but the control steps did not meet the design requirements.
