本发明涉及一种基于分布式潮流计算的风电汇集区域两级分布式仿真方法，属于电力系统风场汇集区域仿真领域。本方法提取前一时刻最后一步仿真计算得到的主干网络数据，作为本时刻第一步主干网络潮流计算初始值；提取本时刻第I-1步风场内子网络仿真计算得到的数据，修改主干网络中风场接入节点注入量；根据获得的数据进行第I步主干网络潮流计算，第I步计算得到的风电场接入点电压向量；将第I步计算得到的风电场接入点电压向量与前步计算的风电场接入点电压向量标幺化后做差值后求无穷范数，若满足最大容忍偏差或计算步数抵达上限时，则完成本时刻主网络和风场子网络仿真。本发明能够近似降低计算负担，提升仿真速度，并适宜于模拟较长时间内风电汇集区域的动态特性。
