The Hybrid Power Generation System using Solar, Wind, and Piezoelectric Energy Sources is designed to provide an efficient and sustainable solution for rural electrification by utilizing multiple renewable energy resources. The system integrates solar energy, wind energy, and piezoelectric energy harvesting technologies to generate electrical power from naturally available sources. By combining these three energy sources, continuous power generation can be achieved even when one source is unavailable or operating at reduced efficiency. In this project, a solar panel converts sunlight into electrical energy, a wind turbine generates power from wind flow, and piezoelectric plates produce electricity from mechanical pressure or vibrations. The generated energy from all sources is conditioned and stored in a rechargeable battery for later use. The stored DC power is supplied to an inverter section consisting of a pulse generator, MOSFET switching circuit, and a step-up transformer to convert the low-voltage DC into usable AC power for operating electrical appliances. A regulated power supply (RPS) provides a stable 5V DC supply to the PIC microcontroller. The microcontroller continuously monitors the voltage levels generated by the solar panel, wind turbine, and piezoelectric module through voltage sensing circuits. The measured parameters are displayed on an LCD module, enabling real-time monitoring of power generation from each source. The generated AC output can be used to operate loads such as bulbs, fans, and other household appliances. This hybrid renewable energy system offers a reliable, eco-friendly, and cost-effective alternative to conventional energy sources, making it particularly suitable for rural and remote areas where grid electricity is limited or unavailable.
