摘要：
When the small-signal stability problem occurs, corrective control can avoid worsening the situation of power system. Based on the Small-Signal Stability Constrained Optimal Power Flow (SSSC-OPF), this paper proposes a corrective control method for dispatching. Owing to the idea of hybrid control, the proposed method can make the system approach optimal point of economy and security for power system through event-driven control in multiple times. This method only needs one optimization calculation to generate control instructions, thus it has a fast decision-making speed, significantly improves the time-efficiency of dispatching in system crisis and breaks through the efficiency bottleneck that other strategies cannot be practically implemented. The simulations on WSCC-9, IEEE-39 and IEEE-145 systems show that the proposed method has high computation efficiency, good control effect and wide prospect of application. © 2020, Power System Protection and Control Press.
