摘要：Stability is an important constraint in power system preventive control against blackouts
triggered by transient instability (TS) after a contingency. The Transient Stability Constrained
Optimal Power Flow (TSCOPF) has a considerable attention in recent years. In this paper, a
novel formulation of Optimal Power Flow (OPF) problem is proposed by incorporating the
transient stability constraints into the conventional OPF problem. Improved Particle Swarm
Optimizer (IPSO) is developed to solve the TSCOPF. The proposed approach is tested on the
Western System Coordinated Council (WSCC) 9-Bus system and IEEE 30-bus system. The
results show that the system stability has been greatly enhanced with the proposed formulation .
