In this paper, the research of reactive power optimization in electric power systems is analyzed. The optimal models are divided into several types and the development trend is analyzed. Then, the shortage of traditional algo-rithms is pointed out. Also, the advantage and disadvantage of typical intelligent algorithms are compared together. The advantage of combined intelligent algorithms is pointed out. The development trend of reactive power optimization is indicated in the end of the paper.
