Dynamic performance improvement of New York state power grid with multi‐functional multi‐band power system stabiliser‐based wide‐area control.

This study demonstrates the application of a wide‐area control scheme based on multi‐functional multi‐band power system stabilisers (MF‐MBPSS) in New York State grid for the purpose of system stability improvement. The aspects of oscillation damping, frequency and voltage closed‐loop control are considered. The study describes useful techniques for placing and tuning of MF‐MBPSSs based on simulation models and suitable techniques for very large power grids. The application of these concepts is demonstrated on a transient stability model of Eastern Interconnection. Results show a reduction of system frequency nadir during generation outages, significant improvement in damping of post‐disturbance swings and capabilities to contribute to long‐term voltage stability using only a modest amount of dynamic reactive power resources.
