Study for renewable energy telemetry using a decentralized cloud M2M system

Renewable energy sources are increasingly used for providing green alternatives to existing energy producers and need to be constantly monitored for optimizing the power grid. Unfortunately, such micro power plants are located in difficult to access remote locations where often only satellite or sparse GSM radio signals are available. In this paper we study the way how to use a decentralized cloud system, based on general systems and RTU (Remote Telemetry Units), for tele-monitoring of such objectives. In our proposed cloud M2M system, each RTU communicates by radio with a telemetry data gateway connected to a cloud computing infrastructure equipped with appropriate software that delivers processed data. Finally, we present the measurement results for a hydro-energy case study and discuss the applicability for other renewable sources such as solar or wind energy.
