Abstract: Study was made on the reactive voltage optimization control method after wind farm with doubly-fed induction generator connected to distribution network. Via analysis to power conditions of doubly-fed induction generator set, the reactive power regulation capacity of doubly-fed induction generator set was given full play for distribution network. The problem to construct reactive
power optimization was converted to a non-linear mixed integer optimization problem which was solved by intelligent genetic algorithm. The IEEE 30-node system was chosen as an example for simulation. Calculation results can provide references of suitable reactive power distribution for distribution network containing wind farm. It verifies the validity of the control method.
Key words: doubly-fed induction generator, wind farm, reactive power optimization, genetic algorithm
