This hybrid AC/DC microgrid facility is unique in terms of kind of sources composed of solar PV, wind turbine-emulator & generator system, Fuel cell (FC) system, Diesel generator and hybrid storage of Battery and Supercapacitor (SC) and AC/DC loads. This is installed in and around a lab complex building in IIT Kharagpur campus to host and test new interface prototypes devices and the control algorithms. The two level control hierarchy and communication structure is developed using local control from NI CompactRIO and supervisory control from OPAL RT OP5600.
