Design of Self Sufficient Urban Microgrids Kumar Harshitha S., Kishore K. Udaya, Kumar A. Sudheer Solar Business Unit, Larsen & Toubro Ltd., Chennai Online published on 6 February, 2020. Abstract Distributed generation takes centre stage in today's rapidly changing energy landscape. Particularly, locally matching demand and generation in the form of microgrids is becoming a promising alternative to the central distribution paradigm. Critical loads such as hospitals, data centres and industrial facilities running highly sensitive processes simply cannot afford to be without power even for a moment. These facilities have traditionally relied on backup generation (diesel generators) to fill the void in an emergency. Similarly, facilities like construction sites, mining sites, etc., run on diesel generators to cater their power needs. However, the ever-increasing prices of diesel, high CO2 emissions and high maintenance costs have forced the customers to rethink on this approach. With reduced costs of solar based energy and with reducing costs of batteries, microgrids are becoming a viable alternative. This paper analyses the design of renewable energy based microgrid for achieving ultimate self-sufficiency.
