Abstract
Superconducting Magnetic Energy Storage (SMES) involves the short or long-term storage of energy in the magnetic field of a superconducting coil. The energy flow between the coil and the power network is regulated by a converter bridge. The benefit of such a device is highly dependent on the switching strategy and control of the converter bridge. As part of a research project involving the construction and operation of a SMES unit at Monash University, independent active and reactive power control has been demonstrated for a converter bridge operating under a Pulse Width Modulation switching strategy. This paper investigates the application of such a device to the problem of dynamic stability enhancement of a power network. Under a reactive-power only mode of control, the SMES device is similar to a Static Var Compensator (SVC). However, under simultaneous active and reactive power control, use can be made of the energy storage aspect of the device to increase its benefit in dynamic stability improvement. An optimal control approach is adopted for the design of the controller and the effect of simultaneous active and reactive power control is assessed.
