Summary on Grant Application Form
Traditionally, the phenomena of inter-area oscillation between generation groups, e.g. England and Scotland, has been avoided through operating point constraints on tie-lines and acceptance of operation at less than thermal capacity. The need to support long distance trading makes such constraints unacceptable. Stability problems can be solved dynamically, rather than avoided through planning, by real power intervention using FACTS devices. The dynamic control must itself remain stable even under changed network topology and generation pattern. Our previous work has successfully applied modem methods of robust damping assignment to large systems.The proposal begins with detailed studies of model order reduction techniques that maintain sufficient detail of power systems yet facilitate controller design. We then recognise that future power systems will contain many FACTS devices for the management of power flow. Using these for damping control requires management of the interactions between them. Analysis of the participation of each FACTS device in each mode of the system will establish which actuators are effective In damping the prime modes. Damping duties for particular modes can then be assigned and non-Interacting, autonomous controllers designed. This will be extended to siting and sizing studies to direct effective deployment of re-locatable FACTS. Case-study system models provided by ABB and its customers will be used for verification. The various (ACTS devices and implementations will be assessed for the operational limits imposed by their ratings.
