The integration of Renewable Energy Sources (RES) into power systems presents challenges such as intermittency, stability issues, and power quality concerns. This work reviews key integration methods, including grid-connected, standalone, hybrid, and microgrid systems, while addressing major stability challenges like frequency fluctuations, voltage instability, and transient response. Traditional controllers such as PI, PID, and PR struggle to manage the nonlinear behavior of RES. Advanced control techniques like Sliding Mode Control (SMC), Model Predictive Control (MPC), and Fuzzy Logic Control (FLC) offer improved performance but have limitations, including chattering in SMC, high computational complexity in MPC, and tuning difficulties in FLC. To overcome these issues, Adaptive Voltage Controllers (AVC) provide a more effective solution by dynamically adjusting control parameters in real time, ensuring superior power quality, fast response, and enhanced system stability. This study highlights AVC as the optimal choice for improving renewable energy integration and performance.

摘要

The integration of Renewable Energy Sources (RES) into power systems presents challenges such as intermittency, stability issues, and power quality concerns. This work reviews key integration methods, including grid-connected, standalone, hybrid, and microgrid systems, while addressing major stability challenges like frequency fluctuations, voltage instability, and transient response. Traditional controllers such as PI, PID, and PR struggle to manage the nonlinear behavior of RES. Advanced control techniques like Sliding Mode Control (SMC), Model Predictive Control (MPC), and Fuzzy Logic Control (FLC) offer improved performance but have limitations, including chattering in SMC, high computational complexity in MPC, and tuning difficulties in FLC. To overcome these issues, Adaptive Voltage Controllers (AVC) provide a more effective solution by dynamically adjusting control parameters in real time, ensuring superior power quality, fast response, and enhanced system stability. This study highlights AVC as the optimal choice for improving renewable energy integration and performance.
