Virtual synchronous generator: an overview [PDF]
Nigerian Journal of Technology, 2019 The continuous increase in the penetration of renewable energy (RE) based distributed generations (DGs) in the power system network has created a great concern on the stability of the existing grid. Traditional bulk power plants, which are dominated by synchronous machines (SMs) can easily support system instability, due to the inherent rotor inertia ...

Virtual synchronous generators dynamic performances [PDF]
2014 International Conference on Electrical Sciences and Technologies in Maghreb (CISTEM), 2014 In this paper, dynamic performances of virtual synchronous generator are investigated. The virtual synchronous generator is based on the synchronverter (VSG) concept which is an inverter that mimics a synchronous generator (SG). The real and reactive power delivered by VSGs connected in parallel and operated as generators can be automatically shared ...

IEEE Transactions on Energy Conversion, 2020 In recent years, the increasing penetration of distributed generation in microgrids challenges the control and coordination of energy resources. Especially in microgrids with virtual synchronous generator (VSG)-controlled converters and conventional synchronous generators (SG), the inherent inertia difference (i.e., the VSG and SG) results in a poor ...
