Optimal load shedding with aggregates and mining queries
2010 IEEE 26th International Conference on Data Engineering (ICDE 2010), 2010To cope with bursty arrivals of high-volume data, a DSMS has to shed load while minimizing the degradation of Quality of Service (QoS). In this paper, we show that this problem can be formalized as a classical optimization task from operations research, in ways that accommodate different requirements for multiple users, different query sensitivities to

Optimal undervoltage load shedding using Quantum-Inspired Evolutionary Programming
IEEE 2013 Tencon - Spring, 2013This paper presents a new technique to determine optimal undervoltage load shedding in a distribution system with load variation. The proposed technique is based on multiobjective approach namely Quantum-Inspired Evolutionary Programming (QIEP). This approach utilised the concept of quantum mechanics in the Evolutionary Programming (EP).

Optimization of load-shedding scheme in an integrated process plant
IEEE Transactions on Industry Applications, 1999An integrated process facility recently went through an update of its existing load shedding scheme due to planned changes in the processes in the coming years. Transient simulations indicated that, by changing the load shedding philosophy, the frequency profile during power shortages could be improved significantly.

Load Shedding Strategies Using Optimal Load Flow With Relaxation of Restrictions
IEEE Transactions on Power Systems, 2008This paper proposes an optimization model to minimize the load curtailments necessary to restore the equilibrium of operating point with relaxation of restrictions. This model can be used for the operation planning of electrical power systems. The developed methodology minimizes the load cuts, limiting them to their importance and establishing ...

Optimal Load Shedding for Voltage Stability Enhancement by Ant Colony Optimization
2009 15th International Conference on Intelligent System Applications to Power Systems, 2009Voltage stability has become a serious treat of modern power system operation nowadays. To tackle this problem properly, load shedding is one of the effective countermeasures. However, its consequences might result in huge technical and economic losses. Therefore, this control measure should be optimally and carefully carried out.

Optimal load shedding management for ensuring power system stability
2016 IEEE International Conference on Power and Renewable Energy (ICPRE), 2016Power system stability is necessary for the secure system operation. Transient instability is regarded as most challenging stability problem for most of the systems; therefore it is of much concern for power system stability. In this paper the power system stability problem has been addressed by reducing transients using a load shedding scheme. A relay

A Physarum-inspired optimization algorithm for load-shedding problem
Applied Soft Computing, 2017Abstract Load-shedding is an intentional reduction approach which can maintain the stability of a microgrid system effectively. Recent studies have shown that a load-shedding problem can be solved by formulating it as a 0/1 knapsack problem (KP).
