This paper studies the influence of carrier motion state on the output characteristics of photovoltaic modules.By using multi-source heterogeneous information fusion,the dynamic model of photovoltaic module output characteristics is established,and the unification of the mechanical parameters of the photovoltaic module motion and the output electrical parameters is achieved.Therefore,the coupling relationship between the maximum output power of the photovoltaic module and the parameters of the carrier motion state is obtained.In order to verify the validity of the proposed model,the simulation system is established in the SIMPACK software platform.The result shows that the maximum deviation between the calculated value and the measured value is 0.67 W,and the maximum relative deviation rate is 3.23%.The proposed model can provide a theoretical basis for the dynamic tracking control method of the maximum power point of the photovoltaic module under the moving carrier,and improve the photovoltaic conversion efficiency.
