Overload Control Strategy Based on Triangular Fuzzy Analytic Hierarchy Process

After the high-voltage transmission line is cut off due to a fault, bearing power will be transferred, which may cause overload. If overload cannot eliminated quickly and scientifically, it very likely that backup protection activated, trigger chain trip or even blackout accidents. In view of this, this paper proposed cross-voltage level optimization load shedding control strategy based on fuzzy analytic hierarchy process. Through step-by-step progression in three indexes degree, importance unit cost, lower-level lines are selected for optimal removal, thus achieving goal optimizing across voltage levels.
