Design and Analysis of a Sustainable Power System for Healthcare Centers Using Renewable Energy Sources
Solar photovoltaic is one of the commonly renewable energy sources using in Ethiopia according to its geographical conditions and availability of ample solar insolation. Solar Photovoltaic (PV) systems have been shown to significantly reduce greenhouse gas emissions and environmental devastation caused by the use of nonrenewable energy sources. Nigist Eleni Mohammed Memorial Referral Hospital, which was used as a case study in this study, is also dealing with these issues of disparity and undependable electrical power supply. As a result, the purpose of this research paper was to carefully analyze how a hybrid combination of solar photovoltaic (PV) and other energy sources can be used to increase the reliability of the existing power supply in Hadiya Zone health centers. This study takes an exploratory case study approach by using a qualitative data collection and analysis method. The data collection methods include measurement, participatory observation, interviews, and documentation. The empirical findings were analyzed and used to calculate the required solar PV components that can be integrated into the existing power system. The results reveal that solar PV with a backup system connected to the power grid and a diesel generator is viable, and it gives solutions to Nigest Eleni Mohammed Memorial Referral Hospital's (NEMMRH) energy security issues. Across all sites studied, the PV/diesel/battery system is the most economically feasible, with a net present cost of $50,748 and a renewable percentage (RF) of 60%. The HOMER software was used for optimization and cost-effective analysis.
