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 ...

Optimal load‐shedding using local information

Electrical Engineering in Japan, 1996
AbstractThis paper describes an optimal load‐shedding policy based on quadratic programming using only some power system state variables after severe generation outages. When generation outage is severe, the imbalance between supply and demand causes a declining frequency. Utilities generators cannot be operated excessively at frequencies above normal.

Optimal load shedding: An economic approach

TENCON 2010 - 2010 IEEE Region 10 Conference, 2010
In this paper an economic criterion based optimal load shedding algorithm has been developed. The objective is to minimize the sum of curtailed load and also the total system interruption cost within the frame-work of system operational and security constraints.

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 using Bacterial Foraging Optimization Algorithm

2013 IEEE 4th Control and System Graduate Research Colloquium, 2013
This paper presents an optimization technique for optimal load shedding in power system known as Bacterial Foraging Optimization Algorithm (BFAO). Load shedding is done by removing a certain amount of loads at appointed locations of a bus system. By doing so, the stability of the system can be improved, as well as the total power losses.

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)

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.

Optimal load shedding methodologies in power systems

Conference Proceedings '88., IEEE Southeastcon, 2003
The current status of research on load shedding techniques is reviewed and the importance of relay setting is discussed. Alternatives for the future are also proposed. Future schemes should be able to precisely identify overload on a system and shed the necessary amount of load.
