Delay Compensation of Demand Response and Adaptive Disturbance Rejection Applied to Power System Frequency Control

IEEE Transactions on Power Systems, 2020
In this paper, a modified frequency control model is proposed, where the demand response (DR) control loop is added to the traditional load frequency control (LFC) model to improve the frequency regulation of the power system.

Frequency control symposium

Physics Today, 1959
On May 12, 13, and 14, 1959, the Thirteenth Annual Frequency Control Symposium sponsored by the Frequency Control Division of the US Army Signal Research and Development Laboratory was held at Asbury Park, New Jersey. Besides 700 participants of industrial, educational, and governmental organizations from the US, the Symposium was attended by a ...

The control of ciliary beat frequency

Trends in Cell Biology, 1993
Ciliary movement is powered by axonemal dynein. This article considers how a signal transduction cascade initiated at the cell membrane may activate outer dynein arms to change the velocity of microtubule sliding and the swimming speed of ciliated cells.

Event-Triggered $H_\infty$ Load Frequency Control for Multiarea Power Systems Under Hybrid Cyber Attacks

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2019
This paper investigates the problem of event-triggered ${H_\infty }$ load frequency control (LFC) for multiarea power systems under hybrid cyber attacks, including denial-of-service (DoS) attacks and deception attacks.

Frequency control developments

Physics Today, 1966
CRYSTAL VIBRATORS and atomic frequency standards are continuing to attract the interest of engineers and physicists. In particular, the energy-trapping concept has assisted in the application of theory to practical quartz resonators. Thus filter crystals have been extended to 125 MHz.

Data-Driven Load Frequency Control for Stochastic Power Systems: A Deep Reinforcement Learning Method With Continuous Action Search

IEEE Transactions on Power Systems, 2019
This letter proposes a data-driven, model-free method for load frequency control (LFC) against renewable energy uncertainties based on deep reinforcement learning (DRL) in continuous action domain.

Robust Load Frequency Control

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

Fundamentals of Frequency Control

2018
In this chapter, the concepts regarding frequency, as a basic parameter of power systems are described. Initially, the physical phenomenon, based on that, this parameter is affected and how it can be controlled are explained. A short historical view on frequency is then followed. It is then discussed how the players in a power system may be affected by

A magnetic amplifier frequency control

Electrical Engineering, 1950
TO SUPPLY power to certain types of shipboard instruments, a source of alternating current is required in which the frequency error must be ±0.1 per cent or less over a range of temperatures, loads, and supply voltages. This need has been met by the use of small motor-driven alternators which run on the ship's d-c power supply.
