Abstract:
The design and execution of a photovoltaic (PV) biomass renewable energy system for rural health clinics in Uganda is presented in this research. The goal of this research is to provide a sustainable and dependable supply of electricity for health facilities in rural places where grid power is limited or unavailable. The system combines solar PV panels and biomass gasification technology to provide electricity for lighting, medical equipment, and other critical needs in health care facilities. The system was designed using a thorough methodology that includes site assessment, load analysis, system sizing, component selection, installation, and performance evaluation. The study's findings showed that deploying a PV biomass renewable energy system for rural health institutions in Uganda is feasible, with beneficial effects on the quality of healthcare services supplied. The system performance analysis revealed that it was capable of meeting the electrical demand of the health facilities and contributed to reducing dependency on diesel generators, hence lowering greenhouse gas emissions. The study's findings highlight the potential of PV biomass renewable energy systems as a viable solution for providing long-term energy access to rural health facilities in Uganda and other similar settings, thereby contributing to improved healthcare services and environmental sustainability. The hybrid energy system has been viewed as an outstanding alternative for rural health facility electrification where national grid expansion and extension are both important and economically unviable. Because of limited fossil fuel supplies, wars, and worldwide environmental concerns, the use of renewable energy sources for electrical power generation, transmission, distribution, and use is becoming increasingly important. Solar energy is the most common type of Renewable Energy Technologies RETS in Ugandan rural areas due to the weather conditions. This is due to the sunrise occurring between 2408 and 4383 hours each year, with average insulations of 5-7 kwh/m2/day in all regions of Uganda. In addition, photovoltaic (PV) power and energy systems are among the most commonly utilized technologies for converting solar power into electricity. Furthermore, biomass resources in Uganda that can be used for energy production are classed as non-plantation biomass, fuel crops (energy plantations), and urban garbage. The total amount of biomass expected is in the order of 50 million ton/y; their gross calorific value is around 800 million GJ, equating to approximately 18 million toe/y. On the other side, energy storage is also combined, which could help to lower peak electricity consumption while smoothing out differences in power supply by fluctuating solar power. The hybrid system considers solar PV and biomass with batteries and converter. A case study was conducted in a distant rural south western districts in Uganda. The primary responsibility is to determine the right component size, reliability, operation, and availability strategy for the system, which will lead to the design and planning of a hybrid energy system for rural health facilities in Uganda.The aforementioned problems prompted a desire to research the possibility of a PV-biomass-battery storage-based generator connected to the grid. A study was undertaken by gathering solar radiation data, comparing average yearly solar radiation, and performing a ranking system. This technology has several advantages over traditional energy producing processes. This study depicts the various system components and their optimal combination for effective power generation utilizing locally available materials. In this research, a proposed strategy for developing PV-biomass energy systems on the electrical loads of rural medical facilities in Uganda is given and used. This approach covers modeling, sizing, and assessing the generation of PV-biomass-battery storage systems that interface with the electrical grid. In addition, a proposed model is presented and used to evaluate the influence of this generation on the capacity, energy, and load displacement of traditional power supply systems, reduction in pollution levels, and energy demand charges of the study electric utility. The learning method makes use of a reference model that describes the system's expected performance. Finally, a comparison analysis of the two created controllers is performed. It outlines the benefits and drawbacks of each controller algorithm.
