要約(英語): This research aims at development of new emergency control schemes using FACTS (flexible AC transmission systems) devices and BESSs (battery energy storage systems) for prevention of cascading outages in bulk power systems. In this paper, use of BESSs is studied for the improvement of short-term voltage stability from the view point of the voltage control. Based on the stabilizing control method proposed in our previous research to improve transient stability, a new control scheme is developed taking into account a finding that the short-term voltage stability is closely related to the angle stability. An additional control system that limits active and reactive power absorption from the grid is applied to the stabilizing control system since the electrical power absorption drops the system voltages. Numerical simulations are conducted on two test systems with BESSs to demonstrate the effectiveness of the proposed method for the improvement of both of the transient stability and the short-term voltage stability under severe fault cases such as a grounding fault and a generator trip. The results show the high potential of the BESSs for the stability enhancement.
