Analysis of inter-area mode oscillations using intelligent system-centric controllers

In this paper, we analyze the inter-area mode oscillations in a two-area power system network using a new class of intelligent adaptive control systems based on a system-centric approach used for the control of multiple generators. The proposed architecture consists of a Model Reference Adaptive Controller (MRAC) operating in parallel with a Radial Basis Function Neural Network (RBFNN) to control individual generator oscillations in the presence of disturbances. The underlying structural feature is the introduction of an Intelligent Supervisory Loop (ISL) to augment a conventional adaptive controller. The main advantage is that the proposed architecture provides individual generator control as well as suppresses inter-area mode oscillations in a two area, five machine, eight bus power system network in the presence of torque and fault disturbances.
