MULTI-SOURCE ENERGY HARVESTING SYSTEM

Abstract

The increasing demand for reliable and sustainable energy has accelerated the development of hybrid renewable energy systems. This project presents the design and implementation of a Hybrid Power Generation System using Solar, Wind, and Piezoelectric Energy Sources. The system integrates photovoltaic panels to harness solar energy, a wind turbine to capture wind energy, and piezoelectric sensors to generate electricity from mechanical vibrations or pressure. Solar energy provides power during daytime with high irradiance conditions, while wind energy complements generation during cloudy or nighttime periods. Piezoelectric modules are incorporated to capture energy from mechanical stress such as footsteps or vibrations, enhancing overall system efficiency. The proposed system is cost-effective, environmentally friendly, and suitable for rural electrification, smart infrastructure, and low-power applications. By combining multiple renewable sources, the system enhances energy security, reduces dependency on fossil fuels, and promotes sustainable developmentThe increasing demand for energy and the depletion of conventional fossil fuel resources have led to a growing interest in renewable and sustainable energy solutions. This project presents the design and development of a MultiSource Energy Harvesting System that utilizes multiple renewable energy sources such as solar, wind, and piezoelectric energy to generate electrical power. The main objective of this system is to ensure a reliable and continuous power supply by overcoming the limitations associated with individual energy sources. In this system, solar panels are used to capture energy from sunlight, a wind turbine or DC generator is employed to harness wind energy, and piezoelectric sensors are used to convert mechanical vibrations or pressure into electrical energy. Since these sources are intermittent in nature, combining them enhances overall energy availability and system efficiency. The generated energy from each source is conditioned using appropriate power electronic circuits such as rectifiers, voltage regulators, and charge controllers before being stored in a rechargeable battery.
