This paper discusses the dynamic performance of a distribution static compensator (DSTATCOM) coupled with an energy storage system (ESS) for improving the power quality of distribution systems. The presented integrated DSTATCOM/ESS compensator is analyzed as a voltage controller, a power factor controller and an active power controller. Modeling and control approaches are proposed, including a detailed modeling of the DSTATCOM/ESS. The multi-level control technique proposed is based on the instantaneous power theory on the synchronous-rotating dq reference frame. Validation of models and control schemes is carried out through simulations by using SimPowerSystems of MATLAB™. The results obtained demonstrate the good performance of the multilevel controller as well as the benefits of its use in the distribution level power quality (PQ).
