Design Of Multiple Facts Controllers For Damping Inter-Area Oscillations: A Decentralized Control Approach, Arturo Roman Messina Jan 2004

Design Of Multiple Facts Controllers For Damping Inter-Area Oscillations: A Decentralized Control Approach, Arturo Roman Messina

A. R. Messina

In this paper, a frequency-domain methodology based on decentralised control theory is proposed to co-ordinate multiple FACTS controllers as well as to minimise the potential for adverse interaction between control loops. First, the concept of dynamic loop interaction in multiple-input multiple-output (MIMO) control systems is introduced. Using the notion of a generalised dynamic relative gain in decentralised control systems, a method is then proposed to determine the best pairing of inputs and outputs for the design of MIMO systems. Finally, a residue-based method is adopted to tune system controllers. The design methodology is tested on a 6-area, 130-machine and 351- …

Use Of Energy And Power Concepts In The Analysis Of The Inter-Area Mode Phenomenon, Arturo Roman Messina Jan 2001

Use Of Energy And Power Concepts In The Analysis Of The Inter-Area Mode Phenomenon, Arturo Roman Messina

A. R. Messina

This paper presents an energy-based small signal method of analyzing low-frequency inter-area oscillations. A comprehensive framework for the analysis of system oscillations is developed based on the analysis of energy relationships in the linear state representation of the power system. This approach provides insight into the nature of the inter-area phenomenon and can be used in conjunction with modern techniques for spectral analysis of complex power systems. The practical use of the proposed methodology is tested on a complex 46-machine, 190-bus test system. Detailed non-linear time domain simulations and frequency domain studies are finally conducted to check the validity of …
