Enhanced Solar Power Generation with OCV-Advanced P&O Hybrid MPPT Algorithm; [태양광 발전 효율 향상을 위한 OCV-Advanced P&O 하이브리드 MPPT 알고리즘]

초록

This paper proposes a hybrid MPPT algorithm, the OCV(Open Circuit Voltage)-Advanced P&O(Perturb and Observe) method, which combines the fast initial search capability of the OCV technique with the precise tracking performance of the Advanced P&O method. This approach reduces the initial MPP search time and minimizes oscillations, improving power generation efficiency in photovoltaic systems. Simulation results using PSIM show that the OCV-Advanced P&O method outperforms conventional P&O and OCV-P&O techniques. Compared to the conventional P&O algorithm, it achieves a shorter initial search time, higher cumulative power output, and reduced oscillations at the MPP. Furthermore, it ensures high stability and efficiency even in dynamic environments with changing irradiance and temperature, making it a reliable solution for enhancing MPPT performance.
