An approach to preparing a functional specification for a unified power flow controller (UPFC) using modular multilevel converter (MMC) is documented by this guide. This guide provides the functional requirements for UPFC project application, including UPFC system composition, function and performance requirements, primary equipment requirements, control and protection requirements, characteristic description, spares, engineering studies, testing, documentation, as well as training of UPFC projects. The intention of this document is to serve as a base specification with an informative annex provided to guide utilities, manufacturers, integrators, and other interested entities to apply a particular UPFC project.

IEEE Draft Guide for Technology of Unified Power Flow Controller Using Modular Multilevel Converter: Part 4 Control and Protection Application
The application of control and protection on a unified power flow controller (UPFC) using a modular multilevel converter (MMC) is specified in this guide, including application considerations, protection functions and performance, control strategies and monitoring functions, as well as test and commissioning approaches. This guide can be used as the basis for design, manufacture, testing and commissioning of UPFC control and protection systems, benefiting both utilities and manufacturers.
IEEE Guide for Technology of Unified Power Flow Controller Using Modular Multilevel Converter–Part 2: Terminology
A glossary and definition of unified power flow controller (UPFC) related areas, including the structure, equipment, control and protection, test, and maintenance utilized by UPFC are specified in this guide. The guide is applicable in flexible ac transmission system (FACTS) such as UPFC, static synchronous compensator (STATCOM), and static synchronous series compensator (SSSC).
IEEE Guide for Technology of Unified Power Flow Controller Using Modular Multilevel Converter--Part 3: Thyristor Bypass Switch
An approach to preparing a specification for the thyristor bypass switch (TBS) of a unified power flow controller (UPFC) using modular multilevel converter (MMC) technology is documented by this guide. The intention of this guide is to serve as a base specification to allow users to modify or develop specific clauses to meet a particular application.
