Abstract :
On-line steady state security monitoring and assessment of power systems based on SMES is a new application of SMES technologies. The location of SMES device is quite important. In the paper, an algorithm to calculate sensitivities of eigenvalues to loads is proposed, and the influences of the generator damping on the movements of eigenvalues are analyzed. Afterward, the steps of selecting the location of SMES as a disturbance source and the method of selecting the capacity of SMES are proposed. The movements of frequency response curves at measured buses with the variations of loads of the EPRI-36 buses system are used to prove the validity of the selected location and capacity.
