the synchronverter (SV) model is
revised and thoroughly examined. Detailed simulation blocks are
clarified and presented using Matlab/Simulink. The aim is to
enhance inertia contribution to approach equivalent real
synchronous generator (SG) and by another meaning gridfriendly
inverter that mimic the operation of conventional SG.
Improvements in the modes of operation grid-connected and
stand-alone modes are obtained. SV is able to transfer seamlessly
between the two modes and then as provide solution for smart
grids and microgrids (MGs). An automatic synchronization unit
is used to minimize disturbances at instant of connection to grid.
Unlike most previous works in this area of research, the present
one simulates also the pulse width modulation (PWM) inverter to
monitor the dc bus condition during different conditions of
operation. The results of simulation are presented to check the
above ideas.
