Online decision-making and emergency control method based on super-real-time simulation

Based on Super-Real-Time Simulation (SRTS), a novel online decision-making and emergency control method of power system is proposed, including two control modes: online pre-decision-making control and real-time control. In this paper, online pre-decision is made by the SRTS and parallel trajectory sensitivity calculation, and real-time decision is made by pure SRTS. A combination of these two decision-making modes is proposed to improve strategy matching degree and to avoid strategy mismatch problem due to changes of operating condition. Finally, an online decision-making and control system is developed based on the proposed method, and closed-loop testing is carried out based on digital real-time simulator to verify the efficiency of the system.
