Aimed at the multi-peak characteristics of P-U output characteristic curves when a photovoltaic array is partially shaded, as well as the problem that the traditional maximum power point tracking (MPPT) method is easy to fall into local optimum and difficult to strike a balance between its tracking accuracy and speed, an MPPT algorithm combining the improved Harris hawk optimization (IHHO) algorithm and variable-step incremental conductance (INC) method is proposed. This algorithm divides the peak region to determine the voltage range where the extreme point exists, so as to narrow the search scope of the algorithm, and then applies the IHHO algorithm for global search in this range. First, the IHHO algorithm optimizes the initial position near 0.8 times the open-circuit voltage in each interval sequentially. Then, the Levy flight is used to optimize the scaling factor at the exploration stage. After the algorithm converges, it is switched to the variable-step INC method for local development. Finally, four kinds of illumination conditions are set up for verification. Simulation results show that the proposed composite MPPT algorithm can effectively avoid falling into local traps under complex shading, low illumination and illumination mutation conditions. In addition, the search speed is improved by 50% on average.
