VSG algorithm is the primary part of the system which interfaced among different storage units, generation units and the utility grid.
Although VSG supplies the inertia to the power system and improves the power system coupling, however, the overall stability of power system drops. In the currently available literature, the primary focus of VSG stability problem solving is on individual parts of the system. Whereas the stability of the overall system is not researched in depth.
