An Alternative Energy Harvesting (AEH) system has been developed to explore the potential of thin-film PZT cells in multi-layered configurations for roadway power generation. This system incorporates a Smart Charging System (SCS) to manage energy storage in lithium batteries efficiently. Each layer of the composite thin-film PZT cells was evaluated for its unique characteristics and energy generation potential. The 2-layer AEH (PZT2L) produced up to 53.28 Wh per day under continuous operation, while the 3-layer AEH (PZT3L) achieved 106.8 Wh per day. In comparison, silicon-based PV panels generated between 19.16 and 38.32 Wh per square foot daily, but with limited operational hours. Despite challenges due to the lower and variable energy output of the PZT cells, the SCS optimized the process for reliable storage. Various analytical techniques are used to assess key parameters such as energy generation capacity, pressure, speed, and overall system performance. These evaluations aim to enhance the efficiency and reliability of multilayered PZT energy harvesting and compare its potential with that of solar cells. The results show promise for the PZT technology as a viable alternative. The ultimate goal is to develop a sustainable energy-generating pad for road infrastructure, potentially transforming future approaches to alternative energy generation.

This research work presents a comprehensive technoeconomic evaluation of a Hybrid Energy, Water, Charging (EWC) system, innovatively using roadside facilities for sustainable energy generation and freshwater purification. The EWC system, combined with solar PV and Sustainable Energy Generating Pad (SEGP) technology, has been developed. This paper evaluates the techno-economic performance of these EWC systems. The economic analysis examines setup costs, operational expenses, and potential revenue from e-bike charging fees, energy sales to a Utility company, and purified water sales, revealing a profitable project with ROI within a 10-year lifespan and determining the Levelized Cost of Energy (LCOE). The study includes two case studies: an EWC microgrid system and a grid-tie microgrid system. The EWC microgrid, suitable for remote areas, shows a Return on Investment (ROI) of 3.6-5 years, depending on the selling rate through energy yield and water production assessments. The grid-tie microgrid, connected to a Utility company and ideal for rural and urban areas, demonstrates 5.2- 6.9 years ROI with additional benefits from net metering. Both scenarios confirm the system's versatility and financial viability, highlighting its potential to advance sustainable infrastructure and resource management toward global clean energy and decarbonization goals.

In response to escalating energy demand and environmental concerns, renewable energy sources have emerged as crucial alternatives to conventional power generation. This paper proposes an innovative solution to address reliability and performance challenges in renewable hybrid PV and Sustainable Energy Generating Pad (SEGP) energy systems by integrating power electronics devices connected to the AC-DC microgrid system. The study uses ETAP software for simulation to identify Busbar instability and the system's performance. Subsequent adjustments to the power electronics devices result in notable system reliability and performance enhancements of about 98-100%, leading to reduced power losses. These findings underscore the transformative potential of this approach in bolstering societal sustainability by sustaining renewable electricity generation and mitigating environmental impacts. The research significantly contributes to ongoing efforts to bridge the gap between energy supply and demand for stable island mode microgrid operation mechanisms, addressing challenges associated with renewable energy generation with alternative energy source methods.
