Fault Tolerance Aspects in Networked Multi-area Power Systems

2006 IEEE Conference on Emerging Technologies and Factory Automation, 2006
In this paper we present a supervisory strategy for load/frequency control problems in networked multi-area power systems. The scheme consists of modifying the nominal frequency set-points and adjusting offsets on the nominal Automatic Load-Frequency Control (ALFC) laws of each area in order to avoid operative constraints violations in response to ...

Event-triggered multi-area state estimation in power systems

2011 4th IEEE International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2011
This paper presents a distributed estimation scheme as a possible solution to multi-area state estimation for power systems. The proposed estimation scheme features data-dependent selective sensing and estimation, namely, event-triggered estimation and communication.

Intelligent Decentralized Controllers for Multi Area Power Systems

2006 1ST IEEE Conference on Industrial Electronics and Applications, 2006
This paper deals with the design of decentralized controllers based on conventional approach and intelligent approach using fuzzy concept. In conventional approach a simple method decentralized Kalman filter based regulator to place closed loop eigenvalues at desired locations by minimizing the linear quadratic performance index of each decoupled sub ...

Set‐points reconfiguration in networked multi‐area electrical power systems

International Journal of Adaptive Control and Signal Processing, 2008
AbstractIn this paper we present a supervisory strategy for load/frequency control problems in networked multi‐area electrical power systems. The proposed strategy exploits a recently developed constrained control methodology named Parameter Governor, which is based on predictive control ideas and combines in a unique framework the actions of Reference

Decentralized Adaptive Load Frequency Control in a Multi-Area Power System

IFAC Proceedings Volumes, 2001
Abstract The emergence of competitive forces in the electricity market and the demand for lower electricity rates will inevitably reduce the degree of co-operation between interconnected utilities. Therefore, the power system centralized control strategy leaves space to a decentralized one. But the main problem is that a decentralized strategy has to

Robust Control of Frequency for Multi-Area Power System

2020 IEEE Region 10 Symposium (TENSYMP), 2020
The problem of compensating frequency disruption during load variation is addressed in this article with the help of an optimal control strategy based on linear-quadratic- Gaussian (LQG) controller incorporated with an integral action. The controller is designed and implemented on a two-area interconnected power system to control frequency through load

Hierarchical economic dispatch for multi-area power systems

Electric Power Systems Research, 1991
Abstract In a multi-area power system, power exchange through tie lines such that the overall cost of the system operation is a minimum is a major economic dispatch problem. In this paper, techniques and methods are presented for solving the economic dispatch problem of radially interconnected power systems. The proposed method, based on a multi-area

Multi-area unit commitment for large-scale power systems

IEE Proceedings - Generation, Transmission and Distribution, 1998
A large-scale multi-area unit commitment is presented using a Lagrangian relaxation approach. The problem with a transmission network of several thousand buses and lines is equivalently modelled by a system with relatively few areas. Crucial tie-lines between areas are directly modelled.

Power system modeling for multi-area regulating market simulation

2005 IEEE Russia Power Tech, 2005
In a power system with many fast and/or large changes in the generation or the consumption, for example in a system with large amounts of wind power, the frequency control is more complicated to handle efficiently. Minimizing regulation costs for the system operator in such a system requires the possibility to simulate the frequency control, but the ...

Load Frequency Control of Multi-Area Restructured Power System

2008 Joint International Conference on Power System Technology and IEEE Power India Conference, 2008
This paper presents the design of a linear quadratic regulator for load frequency control problem in a restructured competitive electricity market with a pragmatic viewpoint. In the practical environment, access to all of the state variables of system is limited and measuring all of them is also impossible.
