PV impacts on dynamic voltage stability

In this paper we discuss the impact of PV on dynamic voltage stability. The power system becomes more vulnerable as we add PV and displace conventional generation, and consequently inertia and VAR support. While PV inverters have the capability to provide reactive power, the fact that most PVs are connected at lower voltage levels limits its usefulness. We use the Dominion Virginia Power's system with different PV scenarios to show how dynamic voltage stability of the system was significantly affected. The purpose of this paper is to increase the awareness to the dynamic voltage stability issues the in case of significant PVs connected to the system.
