This report provides a comprehensive analysis of standalone hybrid energy systems, focusing on the integration of solar PV, wind turbines, and biomass for power generation. The introduction highlights the increasing demand for electricity and the environmental concerns associated with fossil fuels, emphasizing the need for renewable energy sources. The report explores each renewable source individually, detailing their operational principles, advantages, and economic aspects. A case study in Naraingarh, Haryana Village, India, is used to simulate different hybrid combinations using Homer Pro to determine the most cost-effective solution. The report also includes a schematic diagram of a hybrid system and discusses the components of solar PV and wind turbine systems. It also explains the use of photovoltaic technology, the components of a PV system, and the working principles of wind turbines, including their structure and key components. The economic aspects of renewable sources are examined, and the report aims to provide a practical understanding of hybrid energy system design and implementation. The conclusion summarizes the findings and emphasizes the importance of renewable energy in addressing environmental and energy challenges.
