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 ...

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

Adaptive Demand Limiting Control Using Load Shedding
HVAC&R Research, 1995This paper presents a new algorithm for controlling the peak electrical demand in buildings below a target level through load shedding. The algorithm uses statistical methods to determine the load shedding requirements, without unnecessarily shedding loads.

PMU based centralized adaptive load shedding scheme in power system
2015 27th International Conference on Microelectronics (ICM), 2015One of major contingencies of an electric power system is due to imbalance between loads and generated electric power. This leads to instability in the power system and hence to a blackout. Conventional Under frequency Load Shedding Schemes have been widely used, to restore power system stability. However, the analysis of recent blackouts suggests that

Adaptive load shedding of the power system based on neural network
2002 IEEE Region 10 Conference on Computers, Communications, Control and Power Engineering. TENCOM '02. Proceedings., 2003Frequency stability is a part of the power system reliability. To overcome drastically decreasing frequency of the system, usually, load shedding is performed. Automatic load shedding is required to anticipate and enhance the time response. The trained neural network is an alternative method for solving this kind of problem.

Adaptive Load Shedding for Mining Frequent Patterns from Data Streams
2006Most algorithms that focus on discovering frequent patterns from data streams assumed that the machinery is capable of managing all the incoming transactions without any delay; or without the need to drop transactions. However, this assumption is often impractical due to the inherent characteristics of data stream environments.

Buffer-Preposed QoS Adaptation Framework and Load Shedding Techniques over Streams
2006Maintaining the quality of queries over streaming data is often thought to be of tremendous challenge since data arrival rate and average per-tuple CPU processing cost are highly unpredictable. In this paper, we address a novel buffer-preposed QoS adaptation framework on the basis of control theory and present several load shedding techniques and ...

Adaptive Under-Frequency Load Shedding Scheme by Genetic Algorithm
2006Under-Frequency Load Shedding (UFLS) is one technique used in the power industry for many years. The UFLS function is to rescue the system under extreme disturbances and avoid the system collapse. Traditionally, a scheme is designed based on the projected scenarios (considering the summer and winter conditions) as well as the worst generation ...
