ABSTRACT
This paper presents HOMER simulation models for optimizing renewable energy system components in Off grid and Grid connected systems for Covid-19 hospitals. Load profiles of 100 bed and 50 bed Covid hospitals are established critically. Two simulation models are built for each load profile. Optimization of energy system components is conducted based on net present cost and cost of energy. In process of optimization, HOMER simulates all possible configurations and ranks feasible combinations according to TNPC, and lists feasible options. Ten combinations are identified for analysis in each model. The critical analysis of results revealed that, grid connected system proves to be most economic and reliable option for hospital loads. The cost of energy obtained in grid connected system is Rs.9/kWh, whereas for diesel generated connected system costing Rs.22/kWh. This difference is appeared mainly due to higher cost of diesel and variation in the solar and wind energy potential with time of the day. Thus it is concluded that, renewable energy sources can be effectively employed for energizing the Covid-19 hospital in association with grid. © 2021 IEEE.
