Abstract

In the classical (vertical) power systems the synchronous operation of every interconnected synchronous machine (with its inherently rotating masses - inertia) is the main requirement for stable operation. As many of the distributed generation technologies are connected to the distribution network via power electronic interfaces, and do not contain inertia, the power system may show different transient stability phenomena. In this paper, the transient stability of power systems with (inertia less) converter connected distributed generation is explored via the Equal Area Criterion method and compared with that of a traditional (vertical) power system. With the existence of a strong external system, it is found that a system with a higher level of penetration of DG exhibits better stability, as measured by improved critical clearing times of the remaining synchronous generator(s).
