Abstract Battery energy storage is linked to STATCOM dc-link through DC/DC bidirectional converter, DC/DC side and STATCOM side is coupled into a whole by dc-link capacitor. The dq coordinate based on linear decoupling small signal dynamic model is established through analysis of building holistic large signal model, realizing decoupling control of DC/DC side and STATCOM side. Based on this model, DC/DC side charge/discharge power is realized through design of DC/DC current loop controller as well as STATCOM side current-voltage double-loop and power feed-forward term combination controller, realizing DC/DC side charge/discharge power and dc-link capacitor output voltage stability control. Design correctness is validated by Matlab/Simulink simulation and experiment.
