Abstract— The small scale electricity generators such as solar photovoltaic (PV) systems are generally connected to the grid at the primary or secondary distribution and are considered as distributed generation (DG). Often, these small scale renewable generators cannot be directly connected to the grid.
The energy production of a grid-connected PV system depends on various factors. Among these we distinguish the rated characteristics of the components of the PV system, the installation configuration, the geographical siting of the PV system, its surrounding objects, and defects that occur during its operation.
In order to improve the stability of large-scale PV and energy storage grid-connected power generation system, this paper proposes the evaluation method to assess the virtual inertia and damping demand of the VSG emulated by the energy storage, as well as a technique to suppress the forced oscillation by shifting the natural frequency.
