Load Shedding Strategy using Fuzzy Logic

As a perspective to ensure the voltage and fre¬quency electrical network stability, the load shedding consti¬tutes 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 algo¬rithms. 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 shed-ding of a pre calculated proportion loads in order to reestablish the power balance and to lead the electrical network to a new stable condition.
