High DG penetration will seriously spoil short-term voltage stability of load in bulk power system. Simulation results on previous studies by the authors have shown that dynamic voltage support (DVS) capability of DG improves the stability, but experimental evaluation doesn't exist yet. This paper presents the effect of DVS capability of DG on an experimental circuit, which consists of an induction motor, a resistance load, and a compensation capacitor behind a reactance. First, an experimental set up that causes voltage instability without DVS is made up. Second, an improvement in DG inverter control is made to realize low voltage ride-through (LVRT) capability and DVS capability, and the DG's performance is confirmed by voltage sag tests. Finally, the tests on the experimental set up demonstrate that DVS capability improves greatly short-term voltage stability of power system loads, and the experimental results give good agreement with simulation results.
