Abstract :
In this paper, energy storage used to enhance the transient stability of an electrical power system with renewable power generation is investigated. The passivity-based control design method (IDA-PBC) is used to achieve power angle stability and frequency and voltage regulation after the occurrence of a large disturbance (a symmetrical three-phase short circuit transmission line fault). The performance of the control design is illustrated in simulation for: (1) a single machine infinite bus (SMIB) and (2) a two-machine (synchronous and doublyfed induction generators) and infinite bus. The results show that the proposed controller provides improved critical clearing times (CCTs) and an enlarged domain of attraction (DOA) with improved frequency and voltage regulation.
