Coordinated Adaptive Control of Multiple Flexible AC Transmission Systems using Multiple-input-Multiple-output Neuro-fuzzy Damping Control Paradigms

摘要

This article presents a novel online adaptive non-linear multiple-input-multiple-output neuro-fuzzy control scheme for flexible AC transmission systems. The proposed control system syn-ergistically integrates the time-frequency localization property of wavelets with locally controllable membership functions in the structure of neuro-fuzzy Takagi-Sugeno-Kang control. The proposed control scheme is checked for both multiple-input-single-output and multiple-input-multiple-output topologies. The performance of the proposed control system is validated against different contingencies and operating conditions using non-linear time-domain simulations and different performance indices. The results reveal that the proposed control scheme effectively damps the local and inter-area modes of oscillations.
