Transient Stability Assessment and Enhancement in the Realm of Power System Dynamic Security Analysis: A Review and Scope of Methods

Transient stability analysis is a regular routine that has been performed during power system planning and operation stages to ensure the system security under disturbances. This paper gives an overview of the transient stability problem from the perspective of power system security and its operating modes, reviews the conventional stability analysis techniques and non conventional stability analysis methods namely: direct, hybrid direct-temporal and artificial intelligence(AI) based approaches. While reviewing the direct methods more attention has been paid on hybrid-direct methods like single machine equivalent (SIME) and Individual machine equal area criterion (IMEAC). Further, the transient stability enhancement methods based on the transient stability constrained optimal power flow (TSCOPF) have been reviewed comprehensively. At the end, a possible research scope that has been identified through this review is presented.
