Multi-Machine Power System Stabilization Control by Robust Decentralized Controller Based on Optimal Sequential Design

Abstract

This paper proposes a robust decentralized controller based on optimal sequential design. The proposed controller can directly consider the inter-area oscillation mode on design phase. Further, the sequential procedure is applied to design for robust controllers in consideration of other controllers. The best design sequence of the controller is decided by using the condition number. The effectiveness of the proposed controller is demonstrated by comparing it with conventional controllers. Damping of many oscillations for a multi-machine power system is demonstrated through simulations, which considered a three line-to-ground fault for power system disturbance.

A Novel Power System Stabilization Technique using Advanced Genetic Algorithm Optimization Approach

“…Consequently, Dynamic Surface Control (DSC)-based adaptive Neural Network (NN) controller is intended to solve the repeated differentiation of the control input that is observed in the traditional back-stepping technique. A robust decentralized controller based on optimal sequential design is proposed by Yoshitaka et al, [2]. The inter-area oscillation mode on design phase can be directly considered by the proposed controller.…”

“…The methods used for tuning range from pole placement, to the more recent one using the heuristic optimization algorithms like the genetic algorithms [5] and particle swarm optimization [2]. The highly complex, dynamic behavior and nonlinearity of power systems, together with their almost continuously time varying nature, have posed a great challenge to power system control engineers for decades.…”

“…Artificial Bee Colony (ABC) techniques have been used to enhance the stabilization of the power systems. A robust decentralized controller based on optimal sequential design is proposed by Yoshitaka et al, [14]. Moreover, the sequential process is applied to design for robust controllers.…”
