Research on control strategy of bidirectional DC/DC converter for battery energy storage system
Studying interface device of power conversion between power grid and storage battery, in order to improve the performance of the converter, a bidirectional full bridge DC/DC converter based on dual-phase-shift control of battery energy storage system is proposed. Theoretically, after analyzing the working characteristics of the bidirectional full bridge DC/DC converter, according to the transmission power of the system and the ratio of the two sides of the high frequency transformer, the optimum phase variables is deduced. Simplified phase variables realized real-time control of bidirectional DC/DC converter. The dual-phase-shift control algorithm realized the stability of control quantity and improved the transmission efficiency of the converter on the basis of restraining the backflow power in the circuit. At last, A small power experimental prototype is built, the experimental results show that This control strategy can effectively reduce the backflow power in power transmission.
