Review of electromagnetic transient models for Non-VSC FACTS

This paper documents electromagnetic transient simulation models for conventional flexible AC transmission systems (FACTS) that do not employ voltage-sourced converter (VSC) technology. The FACTS controllers included in this document are classified into four categories: (1) shunt controllers (2) series controllers (3) combined shunt and series controllers (4) auxiliary controllers. Modeling techniques of these controllers are reviewed and the key aspects of each model are summarized. A comprehensive list of references is also included in this paper to provide further detailed information to the readers.
