An Overview of Grid-Connection Requirements for Converters and Their Impact on Grid-Forming Control

Paper in proceeding, 2022

The increasing share of converters in the power system results in the need to revise grid-connection requirements and a shift in converter control strategies towards grid-forming control. This paper analyzes and compares existing standards and future trends in specifications for grid-connected converters and highlights commonalities and differences. The key consequences for converter control performance requirements are presented to facilitate the selection of the most suitable grid-forming control structures.
