资源说明:In this paper, a new approach based on hybrid Particle Swarm-Based-Simulated Annealing Optimization
technique (PSO-B-SA) is proposed for solving under-voltage load shedding (UVLS) problem. Undervoltage
load shedding (UVLS) is one of the most important tools for avoiding voltage instability. In this
paper, the UVLS problem is formulated based on the concept of the static voltage stability margin and its
sensitivity at the maximum loading point or the collapse point. The voltage stability criterion is modeled
directly into the load-shedding scheme. In any UVLS scheme finding the global point is very important for
having cost effective economy. The proposed PSO-B-SA methodology is implemented in the undervoltage
load shedding scheme for IEEE 14 and 118 bus test systems. In addition to having better solution,
the global property of the proposed approach plays an important role in on-line applications. Simulation
results show the efficacy and advantage of the proposed scheme
