Abstract: Introduction was made to the improved genetic algorithm, and it was combined with the reactive optimization theory. In virtue of Matlab, this method was applied in multi-goal reactive optimization of wind-generation-set-contained IEEE-14 node and IEEE-30 node system. Algorithm example analysis shows that with the improved genetic algorithm, the active net loss of the goal function was reduced, calculation speed raised. There is theoretical application significance in reactive optimization of wind-powercontained power network.
Key words: improved genetic algorithm; reactive power optimization; wind power network; active power loss
