Frequency control of load swings
Electrical Engineering, 1942The Consolidated Edison Company made a series of tests to determine the cause and extent of system load swings on generators and tie feeders. The results were reported in detail in a previous paper.1 An analysis of these tests indicated ways in which our load dispatching methods could be improved.

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.

IFAC Proceedings Volumes, 1989
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

LOAD-FREQUENCY CONTROL WITH SHORT-TERM LOAD PREDICTION
IFAC Proceedings Volumes, 1987Abstract This paper presents a LFC algorithm based on very short-term load prediction. The application of high order difference ARI(p.d) model fitting random load time series to the on - line very short - term load prediction is described. Linear combination of load disturbance prediction and frequency deviation are used as input signal of LFC.

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.
