DESIGN AND PERFORMANCE OPTIMIZATION OF A HYBRID WIND-SOLAR ENERGY SYSTEM FOR HIGHWAY APPLICATIONS

Abstract

Rapid advancements in technology and the escalating demands of modern consumers have made energy an indispensable component of daily life, necessitating increased energy production. However, the predominant reliance on finite and depleting conventional energy resources presents challenges to energy security. Therefore, it is imperative to explore alternative and innovative technologies to fulfill energy deficit sustainability. The most viable solution to address this challenge is the adoption of renewable energy sources. Vertical-axis wind turbines, when integrated with solar panels, present an efficient hybrid system for electricity generation. The aim of this project was to maximize the efficient utilization of wind and solar energy to achieve optimal electricity generation. To accomplish this, a highway was selected as the project site, providing wind energy due to continuous movement of traffic. This project consisted of designing and testing of a Savonius Vertical axis wind turbine that harnessed energy from both wind and solar sources, with the generated energy being stored in batteries to subsequently power streetlights and other electrical systems. Measurements of wind speed at different time at location site revealed that the average wind speed in these areas is approximately 8.3 m/s, showing the potential for wind energy generation in such environments. The VAWT prototype has generated a peak power of up to 47.1 watts from moving traffic. It was concluded that Savonius Vertical axis wind turbine is ideally able to supply streetlights and other public amenities with power at an upgradable scale. It is recommended to implement and evaluate alike projects to assess their feasibility and efficiency, thereby contributing to long-term sustainability.
