Desenvolvimento de uma interface de monitoramento para mini e microgeração fotovoltaica

Abstract

Since the beginning of the 21st century, the Brazilian energy matrix diversification has been heavily discussed since it still very dependent on hydroelectric plants. Distributed generation (DG) has effectively contributed to this diversification, increasing the number of decentralized plants that use solar energy. Due to the evolution of these decentralized photovoltaic (PV) systems, the monitoring has become fundamental to guarantee operations with fault detection and optimized conversion efficiency. This work presents a remote monitoring interface for mini and microgeneration PV built with Power BI, a Business Intelligence (BI) software created by Microsoft. Power BI enables the treatment, analysis, and sharing of a large amount of data in an efficient and accessible way. The IoT monitoring network installed in the PV plants in Fortaleza - CE, Maracanaú - CE and Colônia - Germany collects solar irradiance, ambient temperature, humidity and wind speed. This data are stored on a server in the cloud via WiFi and Power BI connects to the server to obtain the data. The interface has several views that are available in Power BI. The first three pages provide information about each PV plant. The fourth page presents the monitoring network data in graphs and the last one displays graphs from calculated data. The interface is available online for any user who has the access link.
