Optimal load shedding strategy based on particle swarm optimization

8th International Conference on Advances in Power System Control, Operation and Management (APSCOM 2009), 2009
This paper proposed a new optimization model to minimize power loss and the load curtailments necessary to restore the equilibrium of operating point. The solution algorithm is based on the particle swarm optimization (PSO) method in which the load shedding would be considered as the penalty in the optimization cost function.

Adaptive and optimal under frequency load shedding

, 2008
Power systems in many countries are stressed towards their stability limit. If these stable systems experience any unexpected serious contingencies, or disturbances, there is a significant risk of instability, which may lead to wide-spread blackout ...

Optimization of load shedding system

IEEE Transactions on Energy Conversion, 1993
An optimization algorithm is presented for an underfrequency load shedding system which is composed of several stages that are tripped at preset frequencies. The optimization of this system is considered with respect to a cost function that includes a dynamic part, which is the integral of the deviation from nominal frequency, and a static part which ...

Optimization of a Load Shedding Scheme

IEEE Industry Applications Magazine, 1998
An integrated process facility recently went through an update of its existing load shedding scheme in the context of process changes planned for the coming years. Transient simulations indicated that by changing the load shedding philosophy, the frequency profile during power shortages could be significantly improved.

Optimal load shedding planning with genetic algorithm

2011 IEEE Industry Applications Society Annual Meeting, 2011
This paper proposes a novel planning method using genetic algorithm (GA) to achieve minimization of load shedding. The frequency of a power system declines rapidly when generator outage occurs. The general solution is to install sufficient under-frequency relays to pull frequency back to normal range. In this study, a single machine infinite bus (SMIB)

Optimal load shedding with aggregates and mining queries

2010 IEEE 26th International Conference on Data Engineering (ICDE 2010), 2010
To 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

Load Shedding Optimization: A Scenario of IESCO

2018 International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET), 2018
In this paper, an efficient model for the load shedding optimization problem is proposed. Since it is nonlinear, for simplicity the model is relaxed by using Lagrangian relaxation technique along with the use of Karush-Kuhn-Tucker theorem to obtain an optimal solution.
