Stability and Control of Power Grids

Annual Review of Control, Robotics, and Autonomous Systems, 2022
Power grids are critical infrastructure in modern society, and there are well-established theories for the stability and control of traditional power grids under a centralized paradigm. Driven by environmental and sustainability concerns, power grids are undergoing an unprecedented transition, with much more flexibility as well as uncertainty brought ...

AN ADAPTIVE POWER SYSTEM STABILIZER

IFAC Proceedings Volumes, 1988
This paper presents an adaptive power system stabilizer utilizing the eigenvalue control strategy. The control algorithm is based on the identification of decoupled subsystem model parameters in real-time from local measurements only. The concept of decentralized stabilization of power system electromechanical oscillatory modes is discussed and control

Power and stability in connectivity games

International Joint Conference on Autonomous Agents and Multiagent Systems, 2008
We consider computational aspects of a game theoretic approach to network reliability. Consider a network where failure of one node may disrupt communication between two other nodes. We model this network as a simple coalitional game, called the vertex Connectivity Game (CG).

AN ADAPTIVE POWER SYSTEM STABILIZER

IFAC Proceedings Volumes, 1987
Abstract The evolution of the adaptive control concept in which a controller continuously tunes itself to the changing plant characteristics, has provided an attractive design alternative to the conventional approach. A microcomputer based power system stabilizer using the self-tuning adaptive control concept is described in this paper. The recursive

Electronic Stabilizer for Power Transmission

Transactions of the American Institute of Electrical Engineers, 1947
Voltage regulation of an alternator historically has depended upon variation of the field current, and high-speed regulators have been developed in order to improve synchronous stability. This paper describes a voltage control brought about by varying the output current. A reactive load is connected to the generator terminals.

Microwave Power Stabilizer

Review of Scientific Instruments, 1950
An apparatus for the power stabilization of medium-level microwave power sources, intended for laboratory use, by means of a degenerative feed-back network connected in tandem with the power source is described. An analysis of the operation of the network is presented, based on obtaining optimum stabilizing action and optimum transmission efficiency ...

Saturation and Thermal Stability of Power Inductors

2020 27th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2020
This paper discusses the effects of saturation of power inductors and their thermal stability. The investigation is focused on DC-DC switching regulators, with emphasis on fixed frequency controls. A small-change model is formulated for the assessment of power inductors thermal stability, based on analytical models of saturation and losses.
