"WebThe introduction of renewable energy sources has resulted in converter-tied generation, which has in turn diluted the share of synchronous-machine-based generation. While these converter-tied resources provide energy to the grid, their control schemes have largely relied on following the grid, with little or no explicit grid-forming provisions.
