Delay-Dependent Robust Load Frequency Control for Time Delay Power Systems
TL;DR: In this paper, a delay-dependent robust method is proposed for analysis/synthesis of a PID-type LFC scheme considering time delays, where the effect of the disturbance on the controlled output is defined as a robust performance index (RPI) of the closed-loop system.

Understanding automatic generation control
TL;DR: In this paper, the authors describe what automatic generation control (AGC) might be expected to do, and what may not be possible or expedient for it to do; the purposes and objectives of AGC are limited by physical elements involved in the process and the relevant characteristics of these elements are described.

Simulation and Optimization in an AGC System after Deregulation
TL;DR: In this paper, the traditional automatic generation control (AGC) two-area system is modified to take into account the effect of bilateral contracts on the dynamics of the system, and the concept of distribution companies (DISCO) participation matrix to simulate these bilateral contracts is introduced and reflected in the two area block diagram.

Robust load frequency control using genetic algorithms and linear matrix inequalities
TL;DR: In this article, two robust decentralized control design methodologies for load frequency control (LFC) are proposed, one is based on H/sub/spl infin// control design using linear matrix inequalities (LMI) technique in order to obtain robustness against uncertainties and the second controller has a simpler structure, which is more appealing from an implementation point of view.

Multiobjective H/sub 2//H/sub /spl infin// control
TL;DR: In this paper, a linear time-invariant system with several disturbance inputs and controlled outputs is considered, and the authors show how to minimize the nominal H/sub 2/-norm performance in one channel while keeping bounds on the H/ sub 2/Ω(H/sub /spl infin//-norm performance (implying robust stability) in other channels.
