Application of Binary Search Technique in MPPT Control for Enhancing Power Generation in Photovoltaic Systems; [태양광 발전 시스템의 전력 생산량 증대를 위한 MPPT 제어에서의 이진탐색기법의 적용 방안]

초록

This paper proposes an Maximum Power Point Tracking(MPPT) control method utilizing a binary search algorithm to enhance the power generation efficiency of photovoltaic(PV) systems. In PV systems, the MPPT control is a technique designed to maintain power generation at the maximum power point (MPP) under all conditions. The MPPT control must quickly track the MPP in real-time in response to fluctuations in power generation caused by external factors. To achieve rapid and accurate identification of the maximum power point, this study applies a binary search algorithm, which efficiently finds a target value within a sorted array, to the MPPT control. The performance of the proposed MPPT control method was validated through simulations conducted using PSIM. The results demonstrate that the proposed approach effectively increases the power generation efficiency of PV systems. © The Korean Institute of Electrical Engineers.
