| Abstract: | In order to achieve the fast tracking of the MPP (maximum power point) when the photovoltaic system is in the boot process or the solar irradiation has undergone major changes, a novel conductance increment control algorithm is proposed, which combine the new variable step size method with the compensation step method that is based on illumination changes. The mathematical model and simulation model of the proposed algorithm has been established. The simulation results show that the proposed control algorithm can fast and accurately track the MPP with the oscillation phenomenon eliminated, representing good dynamic performance. |
