Cell Maximum Power Point Tracking Control Strategy for Micro-inverter-based Photovoltaics
In order to more effectively track the maximum power point of micro-inverter-based photovoltaic array cells,u-sing MATLAB software,a simulation model was constructed,through which the P-V curve of photovoltaic array cells was obtained and the feasibility of the simulation was verified.An improved maximum power point tracking(MPPT)con-trol strategy with variable step size disturbance observation method,and corresponding simulation models were construc-ted in MATLAB software,and simulation analysis was conducted on three different disturbance observation methods.Through simulation experiments,it was concluded that,under different light intensities,the improved variable step dis-turbance observation method has the ability to quickly and accurately track maximum power point,effectively reducing os-cillations near the maximum power point,and demonstrate good steady-state effects.
