Benchmarking of Modular Multilevel Converter Topologies for ES-STATCOM Realization

Autor: Sanjay K. Chaudhary, Allan F. Cupertino, Remus Teodorescu, Jan R. Svensson

Publikováno v: Energies, Vol 13, Iss 13, p 3384 (2020)

In recent years, the integration of the high-power static synchronous compensator (STATCOM) and energy storage in the same device has gained interest. Such a system is referred to as ES-STATCOM. Modular multilevel converter (MMC) topologies constitut
