Robust damping controller design in power systems withsuperconducting magnetic energy storage devices

摘要

The decentralized design of low-order robust damping controllersnis presented based on a weighted and normalized eigenvalue-distancenminimization method (WNEDM) employing several superconducting magneticnenergy storage (SMES) devices. These controllers are aimed at enhancingnthe damping of multiple inter-area modes in a large power system. Thisnpaper describes a comprehensive and systematic way of designing thesencontrollers. Nonlinear simulations further verify the robustness of thendamping controllers for various operating conditions
