Abstract
Aiming at the application scenario of DC link of hybrid distribution transformer connecting photovoltaic power generation, energy storage battery and supercapacitor, a hybrid distribution transformer circuit topology consisting of integrated photovoltaic, energy storage and supercapacitor is proposed. The control strategy of each converter connected to DC link is given. The control strategy can not only realize the stable access and full utilization of photovoltaic power generation, but also stabilize the DC link voltage by cooperating with the supercapacitor and the energy storage battery, and improve the overall stability of the system. The correctness of circuit topology and control strategy is verified by simulation in Matlab/Simulink.
