Abstract :
This paper concerns the use of energy functions to study the transient stability of power systems. A new slow-fast energy decomposition of two-time-scale power systems is proposed. This decomposition decouples the slow-system energy associated with the system separation from the fast-system energy. Based on this decomposition, a slow energy function method is proposed to improve the potential energy boundary surface method for direct transient-stability analysis
