摘要：The grid integration of large-capacity renewable energy sources opens operational issues into
power system stability and control. This paper investigates the impact of the synchronverter
control strategy on renewable sources integration. The study proposes an improved control
scheme for the integration of variable-speed wind generators and solar photovoltaic systems into
the power grid. The control strategy based on the synchronverter technology, applied to the gridside
converter for the connection of wind and photovoltaic systems. The parameters of the
converter regulator are tuned based on a specific residues method. The proposed control
performances were evaluated in comparison with the conventional voltage oriented control
(VOC) in terms of accordance with Grid Code Requirements (GCR). Dynamic performances
tested include low voltage ride through, frequency ride through, and fault critical clearing time.
The results show that the synchronverter control ensures better performances, complies better
with the GCR of power system operator and enhances additional reactive power supply.
