Enhancing Energy Harvesting from Photovoltaic Cells Using an Efficient MPPT Algorithm

Problem Definition

In the face of declining fossil fuel reserves and the environmental impact of their use, there is a pressing need to shift towards renewable energy sources. The rise in atmospheric CO2 levels, largely due to the burning of fossil fuels, has contributed to climate change and its associated environmental consequences. As a potential solution, the adoption of solar photovoltaic (PV) systems offers promise in reducing carbon emissions and providing a sustainable alternative energy source. However, a key limitation in the widespread adoption of PV systems lies in the performance of PV cells. Achieving optimal efficiency and reliability in PV cells is crucial for the successful implementation of solar energy technology and addressing the challenges posed by the depletion of fossil fuels and environmental conservation.

Objective

The objective is to address the limitations in the performance of solar photovoltaic (PV) cells by implementing a boost converter and Maximum Power Point Tracking (MPPT) control mechanism. This will optimize power conversion efficiency in the PV system, ultimately improving energy efficiency, sustainability, and reducing reliance on traditional energy sources. Through the use of the Perturb & Observe (P&O) algorithm, the goal is to dynamically track and maintain the optimal operating point of the PV cells under varying environmental conditions. By demonstrating the potential of solar energy as a viable alternative to fossil fuels, the project aims to contribute to a more sustainable energy future.

Proposed Work

The depletion of fossil fuels and the environmental impacts associated with their use have driven the need for alternative renewable energy sources. One such solution is the use of solar PV systems. However, the performance of PV cells remains a challenge in maximizing power conversion efficiency. To address this issue, a boost converter and Maximum Power Point Tracking (MPPT) control mechanism are proposed to optimize power conversion in the PV system. The Perturb & Observe (P&O) algorithm, based on the hill climbing principle, will be implemented to dynamically track and maintain the optimal operating point of the PV cells.

By integrating these technologies into the PV system, the goal is to improve energy efficiency and sustainability while reducing reliance on traditional energy sources. The choice to focus on solar energy as a future energy source is informed by its abundance and sustainability compared to fossil fuels. The non-linear I-V characteristic of PV arrays, along with external factors such as temperature and irradiance, can significantly impact the efficiency of the PV system. By incorporating the MPPT control mechanism and boost converter in the proposed work, the aim is to extract maximum power from the PV array under varying environmental conditions. The P&O algorithm is selected for its simplicity and effectiveness in dynamically adjusting the system to operate at the maximum power point.

By modeling a PV system with these components and algorithms, the project seeks to demonstrate the potential of solar energy as a viable alternative to fossil fuels, contributing to a more sustainable energy future.
