Adaptive underfrequency load shedding and underfrequency load restoration system
2005 IEEE Russia Power Tech, 2005Paper deals with the problem of power system control during emergency situation, caused by generating power deficiency. Deep frequency decline usually is prevented with the help of frequency-actuated load shedding automation. Analysis of existing load shedding system showed possibility of power system blackout due to improper parameters of emergency ...

Adaptive market based load shedding scheme
2015 IEEE Power & Energy Society General Meeting, 2015This paper develops and presents an adaptive market-based load shedding scheme that provides options for adaptive selection of loads in real-time. Therefore an ancillary market-based system where consumers as well as system operator have options to contribute to system security can be evolved.

An Adaptive Load-Shedding Method for Renewable Integrated Power Systems
2023 International Conference on Power, Instrumentation, Control and Computing (PICC), 2023The risk of a blackout or system failure is growing as power networks get more complicated and larger on a regular basis as a result of rising demand and the adoption of contemporary technologies. Frequency stability plays a vital role for the safe operation of a power system.

A Novel Adaptive Load Shedding Scheme for Data Stream Processing
Future Generation Communication and Networking (FGCN 2007), 2007In this paper, we present a novel feedback control-based load shedding scheme for data stream processing. Firstly we apply system identification to establish a dynamic model to describe data stream management system (DSMS), which enables us analyze DSMS quantitatively.

New Adaptive Decentralize Under Frequency Load-Shedding Algorithm
2020 15th International Conference on Protection and Automation of Power Systems (IPAPS), 2020when there is a disturbance in the power grid, some power generator units are disconnected from the grid. The frequency starts to decrease. Therefore, multi-stage frequency relays are used in power grids. The most crucial issue with the conventional method is fixed setting; in the standard method available for such relays, various phenomena are ...

Adaptive load shedding for isolated power systems
IEE Proceedings - Generation, Transmission and Distribution, 1994Emergency control of frequency in an isolated power system is considered. In many such systems, limited load shedding is permitted under certain generation loss conditions to reduce the expense of spinning reserve provision. It is important in these circumstances to minimise consumer disruption through proper-design of the load shedding arrangements ...

Design of adaptive load shedding by artificial neural networks
IEE Proceedings - Generation, Transmission and Distribution, 2005The design of an adaptive load-shedding strategy by executing an artificial neural network (ANN) and transient stability analysis for an electric utility system is presented. To prepare the training data set for an ANN, the transient stability analysis of an actual power system has been performed to solve for minimum load shedding with various ...

Proposal and evaluation of an adaptive underfrequency load shedding method
2018 Simposio Brasileiro de Sistemas Eletricos (SBSE), 2018This work proposes and evaluates an adaptive underfrequency load shedding method. The method makes use of the phasor measurement systems for the monitoring of the dynamic state of the network, estimating the unbalance between the load and generation and adapting the load shedding.

A synchrophasor measurements based adaptive underfrequency load shedding scheme
2014 IEEE Innovative Smart Grid Technologies - Asia (ISGT ASIA), 2014This paper presents a new Synchrophasor-assisted scheme for Underfrequency load shedding (Sy-UFLS) in the events of severe generation-load mismatch. Such a mismatch may pose a threat to the frequency stability of the power system. The proposed scheme focuses mainly on three aspects of load shedding, viz., when, how-much and where to shed the load.

New Centralized Adaptive Under Frequency Load Shedding Algorithms
2007 Large Engineering Systems Conference on Power Engineering, 2007In this paper two centralized adaptive under frequency load shedding algorithms are proposed and analyzed. The objective of these methods is to simultaneously protect power systems against frequency instability as well as voltage instability, following combinational disturbances. After some events in power systems frequency starts to recover, while the
