In large interconnected power grids, it is incumbent on each generating plant to do its fair share in maintaining the security and reliability of the grid. Recently, fault ride-through (FRT) requirements have been receiving the most attention. The article review the roots of transient stability requirements and recent developments in FRT requirements for wind plants. It discusses how wind plant FRT requirements are being imposed on conventional plants with synchronous machines and how interpretations of FRT requirements have been growing to cover some aspects of transient stability. It was concluded with a discussion about how FRT requirements should complement the established reliability criteria that provide the basis for the transient stability of power grids.
