Small-signal angular stability of a power system may be affected considerably by a grid-connected VSWG under the condition of open-loop modal resonance. This chapter introduces the concept of open-loop modal resonance. Why strong dynamic interactions may be induced by the grid-connected VSWG when the open-loop modal resonance happens is examined. Analysis is presented to indicate that the open-loop modal resonance may very likely degrade the small-signal angular stability of the power system. Both the grid-connected PMSG and DFIG are studied.
