Technology Outline (Process Description)

IIT Bombay in collaboration with CDAC-Thiruvananthapuram has developed indigenous inverters which operate in both grid connected and islanded mode. These inverters are deployed at three microgrid sites (Lakshyadweep, Mount Abu and North Eastern Hill University, Shillong). Each site has uniqueness with respect to the end-users. In Lakshyadweep the grid is very weak and mostly on diesel generator. The site includes a residential complex. The inverter deployed at Lakshyadweep is designed to handle harsh and saline environment. There is a wide variety of flexibility in terms of load choice when it comes to the microgrid in Mount Abu. The storage system used is high energy density system i.e., flow battery to manage the supply-demand gap. The third deployment is in Shillong where the load is administrative building. In addition to the ac load in Shillong a separate low voltage dc line is also established to cate to the street lighting. All the systems will be monitored remotely for the standard system parameters and health of the system.
