Hospital Energy Management System for Enhancing Sustainability and Reliability of Power Supply

Hospitals are adopting new technologies to provide modern healthcare facilities to enhance the sense of security and hope among the citizens. However, uninterrupted power supply is highly required in hospitals to run the modern life-supporting equipments. Further, it is observed that the distribution grid outage is quite frequent in many countries. During the grid outage, usually hospitals used diesel generator to meet the critical load demand. However, diesel generator sometime may fail to start in emergency conditions, and it is also not eco-friendly. Hence, this paper developed a grid tied micro grid using Homer Grid, NREL, USA considering actual load profile of cancer hospital Imphal, Manipur, India. Further, Hospital Energy Management System (HEMS) has been developed to enhance sustainability and reliability of power supply to the hospital. Simulation results reveal that the developed grid tied micro grid, which is comprised of solar photovoltaic, battery storage and diesel generator, can meet the critical load of the hospital during occurrence of both.
