Abstract

Aim at the low efficiency of the traditional incremental conductance method and the insufficient adaptability of the orthogonal vector construction of the single phase locked loop, this paper introduces the incremental conductance method combined with the constant voltage method to achieve the maximum power point tracking (MPPT), and uses second-order generalized integrator based phase locked loop (SOGI-PLL) to construct the orthogonal components to achieve the phase locked. In Matlab/Simulink, a simulation model of the single-phase photovoltaic energy storage grid-connected inverter is constructed and simulated. The simulation results show that not only the bus voltage is stable, but also the grid-connected current is in phase with the grid voltage, and the value of THD meets the grid-connected requirements, which proves the effectiveness of the above control method.
