Simultaneous design of multiple stabilisers for improving system dynamic performance. II. Decentralised/hierarchical control of FACTS device stabilisers and power system stabilisers

For pt.I see ibid., vol.1, p.76-80 (2002). In this paper, the interconnected model of an n-machine power system with FACTS devices installed, proposed by the authors in part I, is used to implement a decentralised/hierarchical control architecture. Such architecture allows damping in a very effective way the power system interarea oscillations obtaining a considerable improvement of the dynamic stability of the interconnected power system. The proposed architecture is tested on the IEEE three machine power system with a STATCOM installed obtaining good results.
