Remote Monitoring and Control of Microgrid using Smart Sensor Network and Internet of Thing

Abstract

A Microgrid (MG) is a viable and scalable approach to integrate distributed sources, ensure reliable and secure energy supply to the remote and the mission critical grid. Smarter monitoring, control and energy management is required to ensure economical and reliable operation of the MG. Equipping an MG with smarter sensor for monitoring along with reliable and secured communication among devices are some critical initial steps toward a smart grid approach. We implement a working MG which is controlled by an advance computer based distributed control system (DCS) from ABB Inc. (800-XA system). We deployed smart sensors and internet of things (IoT) for condition monitoring which is integrated with the DCS. Besides grid, automated operation, this state of the art (DCS) also provides data acquisition, accesses to the user friendly human machine interface (HMI) and supervisory control of all critical assets. Both physical and cyber security is provided by proper authentication and access control.
