Determination of Optimal Unit Start-up Sequences Based on Fuzzy AHP in Power System Restoration
The reasonable arrangement of thermal power generating units starting-up sequence during black-up is very important for the fast restoration of the power system after blackout.Based on fuzzy AHP,a new decision-making method for units optimal starting-up sequence is proposed in the paper.Evaluation indexes of units starting-up sequence is determined by the thoroughly analysis of various factors that affect the units starting-up sequence,the hierarchy model for the units optimal starting-up sequence is established and the complementary judgment matrices using trapezium fuzzy numbers is built to calculate the weight coefficient.Then,the comprehensive evaluation value are calculated and the units optimal starting-up sequence is obtained.The method can combine the advantages of both AHP and fuzzy comprehensive evaluation,and help the dispatchers determine the units optimal starting-up sequence quickly.Finally,the effectiveness of the proposed method is validated by the optimization results of the New England 10-unit 39-bus power system.
