Considering Security Congestion Cost of Transfer Capability Allocation by Y-Matrix Method

ZHANG Hong-liang1,WU Jie-kang2,CHEN Guo-tong3,ZHOU Ju2 (1.Guangxi Fangyuan Electric Co.Ltd,Nanning 530028,China;2.Department of Electrical Engineering,Guangxi Univeristy,Nanning 530004,China; 3.Wuzhou Power Supply bureau,Guangxi Electric Net Company,Wuzhou 543002,China)  
This text based on circuit parameter of the power transmission network uncertain characteristic,set up fuzzy optimization model that trade cut down.Restrain fuzzily safely through introducing in this model,has described more effectively that cuts down the question in trade,have realized within the range of permission that the power transmission network operated that optimizes less cutting down amount of trade of models more fuzzily,thus improved the economic efficiency that the electric market runs under congestioning the situation.To count and have work not to block research that cost assign less,have work is it cause voltage lose steady producing circuit loaded important reasonning to lack,we have put forward on the basis of Y-matrix one gains merit,has no work to block the mathematics model that assigns of the cost.Through transmit electricity to a lot of IEEE system some electric transaction of period block the cost and assign artificial calculation.The result indicates,this method has certain economical and practical value.
