Abstract

Energy storage is an effective way to smooth out fluctuations in the photovoltaic power generation. Aiming at the typical application scenarios of the optical storage type AC/DC hybrid system, a power adjustment topology based on the isolated dual active bridge (DAB) is proposed in order to solve the problem of the access and power adjustment of the photovoltaic unit and the energy storage unit. Based on the theory of direct power feedback, a coordinated control strategy for optical energy storage is then designed. A simulation model is built in MATLAB/Simulink and further analyzed. The results indicate the correctness and effectiveness of the proposed method.
