Load shedding strategy application using fuzzy logic

Abstract

As a perspective to ensure the voltage and frequency electrical network stability, the load shedding constitutes a desirable action to maintain the network service quality and to control its vulnerability. In this paper, we propose a new intelligent load shedding strategy applying fuzzy control algorithms. This strategy is based on the estimate, in real time, of the load quantity to shed. Calculation algorithms containing fuzzy controllers generate command vectors ensuring the load shedding of a pre calculated proportion loads in order to reestablish the power balance and to lead the electrical network to a new stable condition.
