Abstract
This project focuses on designing and optimizing a resilience-oriented hybrid polygeneration system tailored to meet the specific energy needs of rural health facilities and teaching hospitals. Hospitals are prime candidates for integrated energy systems due to their continuous operation, consistent occupancy, and diverse energy requirements, which typically encompass electricity, steam for sterilization, domestic hot water, and chilled water for cooling. In rural areas, where grid reliability is often a significant concern, these facilities need decentralized, sustainable, and dependable energy sources to support critical operations, such as Intensive Care Units (ICUs) and Operating Rooms (ORs). The proposed system incorporates three key renewable technologies: Solar Bifacial Photovoltaics, Biomass Energy, and Biogas Systems. The project methodology utilizes Mixed-Integer Linear Programming (MILP) and Pinch Analysis to identify the optimal configuration and operational strategy. Optimization is approached from a TEESR (Technical, Economic, Environmental, Social, and Reliability) perspective, ensuring that the design minimizes carbon emissions and net present costs while maximizing the human progress index and local job creation. Expected outcomes include a significant reduction in Energy Not Supplied (ENS), a 97% decrease in pollutant emissions compared to diesel-only backup systems, and the attainment of nearly 100% renewable energy autonomy for essential healthcare functions.
