The System Lab demonstrator testbed, which is a first-of-its-kind attempt to emulate a Radial Distribution Feeder of a typical Distribution grid. It provides the needed infrastructure to integrate several diverse devices such as smart meters, processing units, sensors, RE systems, IoT enabled hardware, Home automation devices etc. The research outcomes from this work such as low cost smart metering devices, wireless interoperable heterogeneous network, aggregators, IoT middleware, self organizing algorithms, reconfiguration algorithms, line fault detection algorithm, power theft detection algorithm, control station, integration of solar micro grids, real-time data analysis, learning techniques and decision models, smart grid mobile application, and energy management in micro grids and the distribution grid are integrated into this campus level demonstrator.
