This paper describes the dynamic modeling and the control design of a distribution static compensator (DSTATCOM) coupled with ultra-capacitor energy storage (UCES) for improving the power quality of power systems. Three modes of operation are considered, i.e. voltage control for voltage fluctuations ride-through, current/voltage harmonics mitigation and dynamic active power control. New models and control schemes are proposed. The control technique employed is based on the instantaneous power theory on the synchronous-rotating dq reference frame. Validation of models and control algorithms is carried out through simulations in SimPowerSystems of MATLAB/Simulink.
