Massive integration of renewables e.g., wind,
pv and energy storage in hybrid energy systems introduce
new challenges in terms of frequent control due to the
inherent low inertia characteristic of non-synchronous
generators (NSG). In this paper, an extended virtual
synchronous machine (VSM) control strategy is proposed
to provide better frequency support in the hybrid lowinertia
grids. This approach is realized by adding a fast frequency
response (FFR) droop block to the VSM control of
power converter. By applying the proposed control model,
the power converters interfaced energy storage systems
(ESS) are enabled to emulate the dynamic behavior of a
synchronous machine and provide inertia for the grid. Furthermore,
compared to the conventional VSM, which, just
behaves like a synchronous machine, the proposed control
approach provides better frequency support. Simulation
results for an RMS study in DIgSILENT PowerFactory
show the performance of the proposed control in a hybrid
low-inertia grid.
