要約(英語): This paper presents a new simple approach based on a short distance running race in athletics to determine the maximum power peak (MPP) of a photovoltaic (PV) power system to achieve a high speed and searching accuracy. The operating principle of this approach is based on the division of the active area of contestants at the starting line. Each position of the contestant corresponds to a duty ratio value to control the DC boost converter. Based on the proposed athletics running algorithm, the optimal duty ratio value is determined for the load to receive the best electrical power from the PV system. Based on new concepts of regional division and updated positions, the global MPP can be determined precisely with the rapid convergence of the positions to the global maximum power region. Consequently, the proposed method demonstrates excellent tracking ability with high accuracy and zero oscillation amplitude. Simulation results show that the proposed algorithm achieves high efficiency, particularly under partial shading effects.
