STATCOM converters and control: A review

Static Synchronous compensator (STATCOM), a member of FACTS family has become a prominent device for reactive power compensation and dynamic performance improvement of the system. A voltage source converter (VSC) is at the heart of a STATCOM and has been realized by various topologies in literature. Its control can be divided into compensation and DC voltage balance. A review on converters for STATCOM and their control is presented along with the new emerging technologies in the system. One more attribute of STATCOM besides compensation is its use for improving system stability which is achieved through implementation of various control algorithms, switching techniques which have been reported in literature.
