Data Communication and Remote Monitoring using Raspberry Pi in a Solar-Wind-Biogas integrated Micro-grid system

Abstract

Micro-grid integrates the different distributed renewable energy resources such as solar, wind, and biomass. It can operate either in the stand-alone condition or in synchronization with the utility grid. Extensive research is being done on the implementation of SCADA systems for micro-grids that perform efficiently and are cost-effective. The development of effective and cost-effective real-time data acquisition and remote monitoring systems for micro-grid is essential to study the generated and consumed power quality measurement, stability, reliability, and maintenance optimization. Incomplete data and inaccurate measurement of energy output can lead to false conclusions and lost revenue. In this work, we have used Raspberry Pi for data communication and remote monitoring in a solar-wind-biogas integrated micro-grid system. Data acquisition has been done from smart meters of Elite 440-443 series of Secure Pvt. Ltd. Once the data comes to Raspberry Pi it has been used for different purposes like data display, warnings as parameters go off-limit and online remote monitoring. The operation, results and future scope of the developed data communication and remote monitoring system have been studied and analyzed in detail.
