This study provides a comprehensive, transfer function based, analysis of VGS control, which can be used as the basis for the design of VSG transient and steady-state performance. Based on a hardware validated, large signal model, a small signal model and associated transfer functions which describe the changes in real and reactive powers in response to changes in references and grid frequency disturbances. The derived transfer functions are used to obtain insight into the correct design of VSG controllers. The small signal models, transfer functions and associated analysis are validated by comparison with measured results on a scaled hardware system.||Funding Details:||Science Foundation Ireland||metadata.dc.description.othersponsorship:||ESIPP UCD||Type of material:||Journal Article||Publisher:||IET||Journal:||IET Power Electronics||Volume:||12||Issue:||11||Start page:||2965||End page:||2977||Copyright (published version):||2019 The Institution of Engineering and Technology||Keywords:||Synchronous generators; Transfer functions; Power electronics; Synchronous machines; Power grids; Power convertors; Distributed power generation||DOI:||10.1049/iet-pel.2018.5711||Language:||en||Status of Item:||Peer reviewed|
