Abstract: The paper proposes a novel algorithm for optimal load shedding using fuzzy decision tree. In non-correctable emergency, the remedy is load shedding. The presented algorithm is computationally efficient and can be utilised for online voltage security enhancement. It is based on fuzzy decision tree. Due to the feature selection approach of decision trees the method is fast enough for online load shedding of power system. The scheme is based on the notion of the static voltage stability margin. The work presents the load shedding approach for all credible line outages. The result shows the fast and accurate conversion of 'insecure' cases to 'secure' cases for a credible contingency condition. The initial database is prepared by wide variations of loading conditions at all the load buses using traditional approach of continuation power flow method. The effectiveness of the proposed algorithm of load shedding is tested using IEEE-30 bus system.
