摘要：

The researches about the operation of distribution network with wind farms focus mainly on the active-power output of wind turbine and neglect its reactive-power output capability. The power limit curve of doubly-fed induction generator is analyzed and a coordinated active/reactive power dispatch model is built for the distribution network, which considers the randomicity of wind speed, takes the optimality and robustness of dispatch scheme into account, and is solved based on the limit relaxation method. Simulative results show that, the proposed method exploits the active-power regulation capability of wind turbine to improve the voltage stability margin of distribution network and reduce the investment of additional reactivepower instruments;the obtained dispatch scheme has better robustness. © 2017, Electric Power Automation Equipment Press.
