Abstract

The decentralized design of low-order robust damping controllers is presented based on a weighted and normalized eigenvalue-distance minimization method (WNEDM) employing several superconducting magnetic energy storage (SMES) devices. These controllers are aimed at enhancing the damping of multiple inter-area modes in a large power system. This paper describes a comprehensive and systematic way of designing these controllers. Nonlinear simulations further verify the robustness of the damping controllers for various operating conditions
