This study proposes a static synchronous compensator (STATCOM), which cannot only detect and compensate for reactive current according to the real‐time change of grid reactive current, but also maintain the current phase and voltage phase of grid consistent. Aimed at the shortages existing in the control of STATCOM at present, such as the parameters are difficult to adjust and the calculation is very complex, a sliding mode controller for STATCOM reactive current inner‐loop control system is designed. Finally, the control logic is evaluated in Matlab/Simulink, and the simulation results are compared with the traditional proportional integral (PI) control design. It is shown that the proposed method is able to achieve the response performance of the conventional PI method, and has stronger robustness against external disturbance.
