Abstract:

The increasing reliance on solar energy as a renewable power source necessitates efficient energy management strategies to address the intermittent nature of photovoltaic (PV) generation. Maximum Power Point Tracking (MPPT) techniques, such as the Perturb and Observe (P&O) method, optimize the efficiency of solar panels by ensuring they operate at their most effective voltage. However, traditional MPPT control often results in excessive voltage generation, leading to overvoltage conditions that can damage solar panels and connected loads. To overcome this issue, a Modified MPPT-P&O approach is proposed, integrating a Constant Power Generation (CPG) mode to regulate voltage levels and maintain system stability. This method allows the system to transition between MPPT and CPG modes, ensuring that power output remains within safe operational limits. The approach is implemented using PSIM software, a powerful simulation tool for power electronics applications, enabling precise modeling and validation of the proposed control strategy. By adopting this enhanced MPPT method, solar power plants can achieve stable and reliable power generation, mitigating the risks associated with overvoltage and ensuring sustainable energy utilization. This study contributes to improving the performance and longevity of solar energy systems, making them more viable for large-scale deployment.
