Robust-load frequency controller design for Iraqi national super grid system

Abstract EN

This work is intended to design a new robust load-frequency controller for Iraqi National Super Grid System with uncertain parameters.

Riccati equation approach to the stabilization of uncertain system is proposed.

Robust controller that ensures stability of the closed-loop system for all admissible structured uncertainties is designed.

‘Matching conditions’ and Lyapunov stability theory are used to implement a robust stabilizing controller.

Participation factor used to address the interaction between the state variables and the modes in the power system.

This property is used to choose weighting matrix of the state variables (Q).

A linear, time, invariant mathematical model is derived for Iraqi National Super Grid System consisting of six generating stations with various types of turbines.

The proposed approach is applied on this system and simulation program is built to evaluate its effectiveness.
