Digital Load Frequency Control
2020 6th IEEE International Energy Conference (ENERGYCon), 2020Frequency of power supply system needs to be kept constant or fixed irrespective of the varying changes in load demand in order to ensure the well-being of power generating equipment and delivery of good quality power at the demand side. This paper presents an enhanced digital PD controller for Load Frequency Control (LFC) of UAE power system based on ...

Optimal Decentralized Load-Frequency Control
IFAC Proceedings Volumes, 1984Abstract An optimal decentralized load-frequency control of a multi-area intercon-nected power system is developed. It features the optimal design of decentralized load-frequency controller, the observer for unmeasurable local states and load disturbances, and ttie quadratic estimator for discrete tie-line power flow information.

Abstract It is highly desirable that any control system is not affected by modeling errors or parameter variations of a controlled object. This paper presents an application of a robust feedback control system to load frequency control of an interconnected power system. In the design of this control system, parameter variations in a controlled object

Advanced Load Frequency Control
IEEE Transactions on Power Apparatus and Systems, 1972The problem of designing a load frequency control law which reduces transient frequency oscillations (swings) and reduces the number of control signals sent to power houses is investigated. A linear model of an area of an interconnected power system is developed, and a discrete time, linear-plus-deadband, feedback control law is designed.

Constrained Load-frequency Control
Electric Power Components and Systems, 2008Abstract Load-frequency control (LFC) is one of the major problems when dealing with the design and/or operation of electric power systems. Moreover, due to practical and physical considerations, bounds are often imposed on the level of control signals as well as the maximum frequency deviation. Control strategies that satisfy systems constraints, and,

Decentralised load-frequency control
IEE Proceedings D Control Theory and Applications, 1985Consider an LQ problem: \(\min_{K\in \Omega}J(K)\) subject to \(\dot x=Ax+Bu\), \(y=Cx\), where \(J(K)=0.5\int^{\infty}_{0}x'(Q+K'RK)xdt\), \(\Omega =\{K:\) \(F(K)=0\}\); \(F(K)=K(I-C'(CC')^{-1}C)\), \(F(K)=K- diag\{K_ 1,...,K_ M\}\) for output, decentralised (with M local agents) feedback control, respectively. Two theorems are proved: Suppose \(K+L=R^
