This paper explores the application of Superconducting Magnetic Energy Storage (SMES) systems for damping power system electromechanical oscillations. Two issues are discussed: location and controller design. The location of a SMES unit consists of determining the buses of the power system where the connection of a SMES unit will be more effective to damp out the modes of interest. Location also involves the selection of the input variable (bus voltage, bus frequency) and the modulation to be performed (either active or reactive power or both). The basic design of the controller requires the calculation of the controller gain and phase compensation network. Small signal models and corresponding eigenvalue sensitivities will be used to address both location and controller design of SMES systems.
Keywords: Small Signal Stability, Superconducting Magnetic Energy Storage Systems, Eigenvalue Sensitivities, Location, Controller design.
