This work deals with the control, performance and applications of STATCOMs equipped with energy storage for power quality improvements. The additional power quality applications, made possible by the energy storage, include a more complete mitigation of voltage dips. Furthermore, the energy storage also enables a STATCOM to support an entry into islanding operation, by rapid balancing of loads, after tripping of a single feeder. A complete design procedure of the conditioner control algorithm is presented. Proposed control scheme focuses on current harmonic compensation, balancing the unbalance load, fulfilling the reactive power demand of the load and improving the supply side power factor. It is shown that STATCOMs equipped with energy storages, due to the ability of controlling both active and reactive power, can keep the system performance practically unaffected during the same conditions. The designed control algorithm is tested in simulation and experimental conditions. It is proved, that the conditioner with energy storage and the proposed control structure is an effective tool for power quality improvement
