In general the traditional reactive power/voltage optimization is such a single objective optimization problem in which the decrement of active transmission power loss and the restraint of the least control variables are not considered at the same time, besides, the voltage constraints which are called as the soft constraint is not considered while the voltage constraint is processed. To solve this problem the fuzzy linear programming algorithm is led in and the mathematical model is derived by which the fuzzy multi-objective constraint can be transformed into crisp single objective constraint. The results of calculation examples show that the relation among the decrement of transmission losses, the restraint of the number of control variables and to ensure the voltage margin at the nodes can be well coordinated by fuzzy linear programming algorithm. Under the premise of adjustment of finite control variables the violated voltage can be corrected, the transmission losses can be decreased, meanwhile specified margins for all nodes can be ensured.
