Nonlinear decentralized control of large-scale power systems
Yi Guo,David J. Hill,Youyi Wang +2 more
TL;DR: This paper describes an application of nonlinear decentralized robust control (Guo, Jiang & Hill, 1998) to large-scale power systems and uses nonlinear bounds of generator interconnections to achieve less-conservative control gains.
Journal ArticleDOI
Robust decentralized nonlinear controller design for multimachine power systems
TL;DR: Simulation results show that the proposed robust nonlinear decentralized controller can greatly enhance the transient stability of the system regardless of the network parameters, operating points and fault locations.
Journal ArticleDOI
Global Transient Stability and Voltage Regulation for Power Systems
Yi Guo,David J. Hill,Youyi Wang +2 more
TL;DR: In this article, a global controller is proposed to co-ordinate the transient stabilizer and voltage regulator, which is smooth and robust with respect to different transient faults in a single-machine infinite bus power system.
Journal ArticleDOI
An Improved Input Delay Approach to Stabilization of Fuzzy Systems Under Variable Sampling
TL;DR: A novel Lyapunov-Krasovskii functional is defined to capture the characteristic of sampled-data systems, and an improved input delay approach is proposed, and new stability and stabilization criteria are obtained in terms of linear matrix inequalities (LMIs).
Journal ArticleDOI
Nonlinear output stabilization control for multimachine power systems
TL;DR: In this article, a robust decentralized nonlinear control scheme is proposed for multimachine power system stability enhancement, which consists of a novel dynamic direct feedback linearization (DFL) compensator through the excitation loop to cancel the nonlinearities and interactions among generators and a robust feedback controller to guarantee the asymptotic stability of the DFL compensated system considering the effects of dynamic output feedback and plant parametric uncertainties.
