Current Projects

Protection methods for active distribution networks with high

penetration of distributed generation.

UK Generic Distribution System (UKGDS) model in order to

provide a common base for the simulation and analysis of theimpact of distributed generation on the operation, performance,

economics and development of the UK distribution networks.

Control of doubly fed induction generators for wind farmoperation.

Control of DFIGs for wind farm operation

IEA Annex XI Topical Expert MeetingNovember 9-10, Dublin, Ireland

Development of control schemes that enable a DFIG to contribute to

network operation and to satisfy new Grid Code requirements:

Voltage control and recovery following network faults. Frequency regulation following loss of network generation.

Positive contribution to network damping.

Fault ride through capability. Compatibility with conventional generation dynamic characteristics.
