A new intelligent algorithm for load shedding against overload in active distribution networks

To improve power system reliability, it is important to reduce the amount of load shedding when a contingency occurs. Along with a comparison of the conventional load shedding methods, this paper presents an intelligent approach based on a centralized coordinated algorithm using a set of influence coefficients. The proposed method divides power system into a set of subsystems with the minimal mutual influence to minimize the amount of considered disturbances. A 28-bus test system is used to study the applicability of the proposed approach. A case study shows that the proposed algorithm can reduce the complexity and provide a high level of fault tolerance while keeping the required accuracy.
