Abstract
Photovoltaic (PV) systems are essential in the transition to renewable energy, offering a clean and sustainable alternative to traditional power generation methods. This paper focuses on enhancing the efficiency and stability of grid-connected PV systems through the integration of Model Predictive Control (MPC) with Proportional Integral (PI) control. The research demonstrates that the combined MPC-PI approach significantly improves the system's ability to maintain stable voltage and current outputs, even under varying environmental conditions such as changes in irradiance. Simulation results show that the integration of MPC reduces transient effects and stabilizes the PV output more effectively than using PI control alone. The enhanced control strategy not only ensures more consistent and reliable power generation but also optimizes the overall efficiency of the PV system. The findings highlight the potential of MPC in improving the performance of grid connected PV systems, making it a valuable tool for advancing renewable energy technologies.
Description
This dissertation focuses on improving the efficiency and stability of grid-connected photovoltaic (PV) systems. The research investigates the integration of Model Predictive Control (MPC) and Proportional-Integral (PI) control to optimize power output and system performance. By using this dual control method, the study demonstrates significant improvements in maintaining stable voltage and current under changing environmental conditions, such as fluctuating solar irradiance.
Key findings include enhanced system responsiveness, reduced transient effects, and more consistent energy generation. The research highlights the potential for MPC-PI integration in renewable energy applications, especially in grid-connected PV systems, to ensure efficient and reliable solar energy harvesting.
For a detailed view, the dissertation covers topics like Maximum Power Point Tracking (MPPT), the design of control algorithms, and the use of simulations to validate the effectiveness of the proposed control strategies.
